    UAVs in Russian Armed Forces: News #2 - Page 3 Empty Re: UAVs in Russian Armed Forces: News #2

    Post  Cyberspec on Mon Jun 22, 2020 8:32 am

    I found the article I was reading a while back (March 2020) which has a lot of interesting info


    "Altius" is a heavy Russian long-range UAV with a maximum combat load of more than a ton. The UAV made its first flight in August 2019. In February 2020, the official website of the Russian defense Ministry reported that the final version of the drone was named "Altius-U". The deployment of production of a heavy reconnaissance and attack drone is planned to be carried out at the facilities of the Ural plant of civil aviation , which is currently engaged in development work on this topic.

    Soon, the Russian aerospace forces will have a new heavy reconnaissance and attack UAV "Altius", which will receive elements of artificial intelligence (AI). the UAV will be able to operate autonomously without the participation of an operator, as well as independently interact with the promising Russian fifth-generation fighter su-57.


    It is reported that the new reconnaissance and attack drone will be able to independently plot a route to a target or a given patrol area without the help of a human operator, bypassing the air defense zones of a possible enemy, as well as detect and attack important ground targets: missile launchers, communication nodes, headquarters. A device with such capabilities is not yet available to the Russian aerospace forces.


    As reported by the newspaper "Izvestia» with reference to its own sources in the military-industrial complex, the country has already begun work on creating an updated version of the heavy reconnaissance and strike drone "Altius-U". The new UAV will receive elements of the AI system, and it will be possible to remotely control the device from the su-57 fighter. It is reported that all the necessary equipment that will give the UAV its "brains" will be installed on the device until the end of 2020, after which the period of technical testing of the new product will begin.

    It is assumed that the elements of artificial intelligence will give the device new capabilities, including the ability to attack ground targets independently. Having obtained the coordinates of the target, the UAV will be able to use its onboard computer to create an algorithm for finding the optimal route to the target of attack, as well as calculate the most suitable point for dropping bombs.

    All this the drone will be able to do without the help of an operator, while the combat drone will receive all the information from the headquarters about the air situation and the location of enemy air defense facilities in real time and build its flight, processing the incoming data. After completing the combat task, the heavy UAV will be able to return to the base in automatic mode along the safest route or return to the patrol zone and continue to solve reconnaissance tasks.


    It is worth noting that currently military drones at all stages of flight try to control operators working from the ground. AI elements installed on Altius should help reduce the burden on operators of unmanned complexes, which is especially important for long flights and long patrols. For a large reconnaissance and strike vehicle, this is especially relevant, since such a UAV is able to stay in the sky for more than a day.


    At the same time, today, not all the technical data of the UAV is still known. For example, in February 2018, the official website of the Ministry of defense of the Russian Federation reported that the heavy UAV "Altius" will be able to carry up to two tons of combat load. But today in the press, including on the thematic site of the Ministry of defense "Zvezda", you can increasingly find other data about the payload of the device – up to 1000 kg.


    The new Russian unmanned aerial vehicle Altius is built according to a classic aerodynamic scheme with a high-placed wing of large span and a V-shaped tail. It is known that "Altius" is built with a wide use of composite structural materials. The power plant of the device is represented by two turboprop engines located on the wing cantilevers, the engines drive two pull screws. Apparently, we are talking about VK-800S engines developed in the Klimov design Bureau. This engine is designed for installation on light aircraft and helicopters (version VK-800V) and produces a take-off power of 800 HP. The approximate wingspan of the UAV is up to 30 meters, the length is about 12 meters, and the take – off weight is more than six tons.


    In 2019, the UZGA plant presented a modified version of the unmanned vehicle, which received a satellite communication system. With the use of such a system, the flight range OF the UAV "Altius" is limited only by the amount of fuel on Board. According to experts, the appearance of such a system allows a reconnaissance and strike drone to conduct reconnaissance and attack targets at a distance of hundreds or thousands of kilometers from its base. It is known that in the sky "Altius" can be from 24 to 48 hours, and the maximum range of its flight should be 10,000 kilometers. At the same time, the device will be able to conduct reconnaissance from a height of 12 thousand meters.


    The features of the device also include its equipment with an inertial navigation system SP-2, which should reduce the possibility of detecting the device in the air, providing the UAV with additional resistance to induced interference and work in the conditions of electronic countermeasures from the enemy.

    It is assumed that the UAV will be able to carry gliding bombs "Grom-2" with a total weight of 598 kg (mass of the warhead 480 kg) and a launch range of 10-50 km, or guided missiles "Grom-1" with a starting mass of 594 kg (mass of the warhead 315 kg) with a launch range of up to 120 km. This assumption was put forward by the journalists of Izvestiya.

    It is planned that "Altius-U" will enter service not only with the VKS, but also with the Russian Navy.

    From what I understand the main issue with this UAV is that the diesel engine (that is the same as on the basic trainer yak-152) is produced in Germany (even if the designer is a russian engineer and it was developed mainly from russian investment money...)...

    I already wrote in another post  (I don't remember if in this or in another thread) that there were plans to move production of such engine to Russia, but I do not know if there was any progress on this.

    The issue is not only the assembly but also all the supply chain and so the production of parts and engine subsystems...


    By the way even for large engine manufacturers many parts are only designed, but the productions are made by other companies, and the engine manufacturer is then responsible of checking them and  assembling everything together...

    But if that is the case then export to Russia should have been blocked in 2014 when the EU pretty much banned exports to Russia because of the Crimea...


    It now reportedly has the domestic VK-800S engines, which are also to be used on the L-410

    So will they be using the VK-800 engine in the Yak-152 trainer too?

    That is good news because isn't the VK-800 going to be used in the Ansat and Ka-226 helicopters too?

    Found this article from last year on RT:

    "Solves the issue of sanctions risks": how is the development of a new Russian aircraft engine progressing
    March 9, 2019, 01: 09
    Alex Sakusen

    In 2020, Russia plans to certify an aircraft with the latest VK-800 turboshaft engine. This was announced by the lead designer of the powerplant project Vitaly Loginov. In 2019, the unit should pass bench tests. VK-800 is a family of engines for light aircraft and helicopters with a load capacity of 1-1. 5 tons. Russian power plants should replace foreign engines. According to experts, the new engine will give an incentive for the development of the aviation industry and regional transportation, as well as reduce dependence on foreign manufacturers.

    In Russia, the development of a small-sized turboshaft engine VK-800 is being completed. This was stated by the lead designer of the powerplant project Vitaly Loginov, speaking at a scientific and technical seminar at the Central Institute of aviation engine engineering (CIAM) named after PI Baranov. According to him, in 2020 it is planned to certify the aircraft equipped with the VK-800.

    "A mock-up Commission has already been held with the participation of specialists from the CIAM certification center. This year, we expect to work closely with the Institute: we plan to use the CIAM and SIC CIAM stand base for conducting certification tests. Technical tasks have already been discussed and draft agreements have been sent out," Loginov said.

    VK-800 is being developed at the Ural civil aviation plant (UZGA, Yekaterinburg) and UEC-Klimov (Saint Petersburg). In the near future, the aircraft-type engine (VK-800S) will be assembled "in iron" for certification tests.

    "In 2018, the first prototype engines were tested, and more than 60 successful launches were performed on them. For conducting flight tests of the engine as part of the aircraft, two regional aviation aircraft have been allocated, one of them is being converted into a flying laboratory," the CIAM website says.

    Serial production of the VK-800 will be launched immediately after receiving the certificate. The engine Assembly will be handled by the scientific and production center "Shovels. Compressors. Turbines" (near Volokolamsk). This enterprise produces most of the components for VK-800. The rest of the units are produced by Omsk engine-building design Bureau, UEC-Perm motors, Metalist-Samara, and UNPP Molniya (Bashkortostan).

    "The development is focused on creating a modern reliable, lightweight and inexpensive fuel-efficient engine. The level of engine parameters is selected based on the application conditions of a used model of a centrifugal compressor and single-stage uncooled turbines. These features simplify the design of the engine and reduce the cost of its production and operation," the UEC — Klimov website notes.
    Switching to a new family

    VK-800 will become a turboshaft engine, which will be used to create powerplants for light-class aircraft and helicopters with a load capacity of 1-1. 5 tons. As Oleg Panteleev, Executive Director of AviaPort Agency, explained to RT, "this will be a family of engines based on a single gas generator."

    "All powerplants will have a common dimension, but for each machine our engineers will develop a separate engine modification taking into account the specifics, flight mode, etc. Such unification is widely used in the world, as it allows you to reduce the cost of development and mass production, " Panteleev said.

    At the moment, it is known that after the completion of certification tests, the VK-800 will be installed on the l-410UPV-E20 multi-purpose aircraft, whose production has been localized at the Ural civil aviation plant since 2016. This machine is widely used in the regions of the Russian Federation for transporting cargo (about 1 ton) and passengers (up to 19 people). The Ministry of defense also owns a small fleet of aircraft.

    The L-410 was created by the Czechoslovak enterprise Let (now Aircraft Industries) in the late 1960s for local airlines of the socialist camp countries. The main customer of this machine was the Soviet Union. Over 800 units were sold in the USSR.

    The L-410 proved to be an economical, unpretentious and user-friendly multi-purpose aircraft. Due to the high demand, it has been repeatedly improved. Currently, 100% of the shares of Let Kunovice belong to the Ural mining and metallurgical company.

    "The L-410 is an extremely successful aircraft, especially for Russian conditions. The need for it is still very great. When installing new avionics and replacing individual units and assemblies, this is a modern machine with a good export potential. It is quite logical that Russia has decided to localize production of the L-410 in the Urals, " Panteleev said.

    The development of the Russian engine is important, because now the L-410 is equipped with M601 and H80 engines of the Czech company GE Aviation Czech (Walter), which is part of the division of the American Corporation General Electric. The appearance of the VK-800 will save UZGA from the need to purchase foreign units.

    According to "UEC-Klimov", the VK-800 line is planned to equip light multi-purpose helicopters "Ansat", Ka-226, Ka-126 (Ka-128), Mi-54 and other domestic rotorcraft, which are now being put on foreign engines. Thus, the Ansat is equipped with an American PW-207K unit, and the Ka-226 is flown by Rolls-Royce (great Britain) and Safran Helicopter Engines (France).

    "Unfortunately, Russia was almost deprived of its own engines for light-class aircraft. These are echoes of insufficient attention to small aircraft on the part of the Soviet state and a consequence of the economic collapse of the 1990s. As a result, our industry was forced to create helicopters without domestic engines," Vladimir Popov, an honored pilot of the Russian Federation, explained in an interview with RT.

    However, the expert is sure that with the beginning of the serial production of the VK-800, the situation will change dramatically.

    According to him, the transition of domestic aviation to a new family of power plants will be completed during the 2020s. Western sanctions, according to Popov, will only give a positive dynamic to the process of import substitution.

    "Thanks to the VK-800, the aviation industry will receive an additional incentive for development. Now all light helicopters and aircraft can be fitted with domestic engines that are no worse than imported ones. We can expect that after this, the demand for light — class aircraft products will increase, including from state customers, including law enforcement agencies that prefer not to buy equipment with foreign aggregates," Popov said.
    "In fact, the new generation»

    VK-800S surpasses its foreign counterparts in a number of characteristics — takeoff power (900 HP against 850 HP in the Czech H80) and economy. As for the specific fuel consumption, the Russian engine it is 0.243 kg/HP per hour, while the H80-0.269, M601F-0.287. According to experts, the VK-800S meets all modern requirements.

    In the coming years, Russian engineers plan to develop more advanced modifications of the VK-800. Speaking at the CIAM conference, Yuri Ravikovich, Vice-rector for research at the MAI, proposed to abandon the oil system and create a " dry " engine — this type of unit is characterized by increased power and reliability.

    "If we talk about helicopter manufacturing, the VK-800 is actually a new generation for our country. UEC-Klimov has extensive experience and serious competence in the production of engines such as the TV2-117 and TV3-117. But these are Soviet-era powerplants, and the VK-2500 was created in 2001 in cooperation with the Zaporozhye "Motor-Sich". In turn, the VK-800 is being created, so to speak, from scratch. Moreover, all components, according to the developer, will be Russian, " Panteleev said.

    According to CIAM, " the creation of a family of engines based on the VK-800 gas turbine for aviation equipment has become a tool for solving the state task of developing the national transport network, in particular in the regions of Siberia and the Far East."

    The project is directly supported by the Ministry of industry and trade.

    Vladimir Popov is convinced that the appearance of the VK-800 on the market will stimulate the development of small aircraft and intraregional transportation in the Russian Federation. According to him, the new domestic engine will naturally remove the restrictions that exist for aircraft manufacturers due to their dependence on foreign products.

    "I think that the VK-800 family will be competitive and with proper state support will displace Western engines from the domestic market. The account will go for hundreds of units, which means that the funds invested in the development will pay off fairly quickly. In addition, we completely close the issue of sanctions risks. Great prospects open up for small aircraft, which plays the role of the circulatory system in the economy of our regions, " Popov stressed.

    A bit long but seems to cover most of my questions...

    Russian version: https://russian.rt.com/russia/article/609213-importozameschenie-dvigatel-vk-800

    I used Yandex to translate to English, but I would think the engine is a little too big for the Yak-152 so they probably still need to move production to Russia for that.

    The engine on the yak-152 is a 500hp diesel engine, while VK-800 is a turboprop engine of about 800/850 hp.

    They are not really the same...

    Of course the availability of that engine could allow Russia to develop a new large UAV with a single turboprop engine, but it won't be altius and it will require quite a but of time...

    Similar info to Garry's post...

    The VK-800 is intended for light-class aircraft: Ka-26, Ka-126, Ka-226, Mi-54 and Ansat helicopters, as well as aircraft for the L-410 and Altair UAVs. In addition, the engine will be installed on a new multi-purpose light aircraft, which is being developed to replace the famous "An-2".

    It is a very small looking engine... compact... especially compared with the propeller it drives...

    Last we heard about the replacement for the An-2 is was going to be a high wing monoplane scaled down a little.

    It would be interesting as a pusher propeller as a speed booster for a high speed helicopter...

    People for drones: training of crews of shock drones has begun

    Deliveries of serial UAVs "Orion" and "Altius" in combat units are expected next year


    For the latest reconnaissance and strike drones, Altius and Orion VKS began to train crews. It is expected that by the end of the year the first calculations will be able to independently carry out training and combat missions . Serial samples of air "hunters" will appear in the troops next year, experts say. Particular attention will be paid to the use of drones in conjunction with manned aircraft.

    Drone training

    The aerospace forces began training crews for heavy reconnaissance and strike drones, sources in the Defense Ministry told Izvestia. The first "Orions" have already entered the training centers. According to the interlocutors of the publication, the larger Altiuses are still on the industrial sites. Their crews study theory and train on simulators. It is planned that training on real equipment will begin next year.

    Earlier, the commander of the videoconferencing, Colonel-General Sergey Surovikin, said that the first serial production UAV complex of medium range at the beginning of the year was transferred to one of the training centers. According to him, the equipment of combat units with medium and long range drones is planned for early 2021. Particular attention will be paid to their integration into the reconnaissance and strike contours of the Armed Forces and their joint use with manned aircraft.

    In April, Nikolai Dolzhenkov, the general designer of the Kronstadt group of companies, announced that he had signed with the Ministry of Defense an act of technical acceptance of the first complex of three Orion UAVs and a ground control station for them. Thus, according to him, the stage of trial operation of the equipment began. The military department has already had additional wishes, in connection with which drones will be finalized.

    Russia’s latest Orion reconnaissance drones receive gunship’s navigation system

    MOSCOW, July 9. /TASS/. The Orion advanced reconnaissance and surveillance drones received the navigation system of the Mi-28NM helicopter that is capable of operating autonomously, the press office of Radio-Electronic Technologies Group (KRET) reported on Thursday.

    The strapdown inertial navigation system produced by specialists of the Ramensky Instrument-Making Factory (part of KRET) is designated to determine an object’s location, comprehensively process and issue navigation and flight information. The system was previously successfully employed on Mi-26 and Mi-28NM helicopters and was adapted for a drone, the press office specified.

    "The systems were successfully tested on prototypes of drones and showed a high level of their functionality and reliability. The navigation systems based on units with ring laser gyroscopes are unique precision instruments capable of autonomously determining the coordinates and parameters of an object’s movement even in the absence of ground, sea or space signals," the press office quoted KRET First Deputy CEO Vladimir Zverev as saying.

    the TVS-2-DT (An-2MS) is the aircraft and has a honeywell engine in it currently which produces 1,100shp and this new proposed engine is 850shp thats quite a drop in power, and the TVS is advrtised to carry 3.5tons will this new engine be capable? losing 250shp is a lot i dont see why they would damage potential sales by putting in a weaker engine making the aircraft less capable. and just to point out this engine is similar in comparison to the L-410 which carries 1-1.8 tons and the new TVS carries 3.5 tons thats pretty much double to L-410 so i doubt this new engine will be suitable for the TVS

    The article I posted says 900hp takeoff power, and the upgraded and modernised aircraft can carry a 3.5 ton payload, the original An-2s these aircraft will actually be replacing are designed to carry 12 people and cargo to a weight of about 2 tons.

    The last information I read on the subject suggested that they were going to radically reduce the size and weight of the new aircraft and go with a high wing monoplane... 900hp would be plenty of power for such an aircraft.

    3.5 tons payload sounds nice, but if it isn't actually necessary then a lighter engine could be more useful.

    Of course it would not take much to scale the engine up a little for say 1,200hp... wasn't there a 1,300hp VK type engine for Il-114 sized aircraft... a derated version of that would probably be fine.

    In terms of drones the numbers of engines in the range of 500hp to 1,500hp would be very useful...

    The last information I read on the subject suggested that they were going to radically reduce the size and weight of the new aircraft and go with a high wing monoplane... 900hp would be plenty of power for such an aircraft.

    3.5 tons payload sounds nice, but if it isn't actually necessary then a lighter engine could be more useful.

    Of course it would not take much to scale the engine up a little for say 1,200hp... wasn't there a 1,300hp VK type engine for Il-114 sized aircraft... a derated version of that would probably be fine.

    In terms of drones the numbers of engines in the range of 500hp to 1,500hp would be very useful...

    Nothing much has been said about the aircraft recently but I agree just like the Honeywell engine there is various versions with different power so to add 200-250hp shouldn't be hard. And although u most likely find aircraft rarely fly to its full capacity it's always handy to have that capability of 3.5ton. I really do think that the new IL-112 and tvs dts aircrafts will be great sellers on export market once they are for sale. Many countries have used, still using both An-2 and An24/26 and are looking to replace.

    The il-114-300 will have the TV7-117 ST engine with 2800/3000hp... however there is in development an engine with about 1650hp.

    It is not a problem the drop in power between the an2 and the new baikal aircraft, as there are limitations in the regulations for newly built aircraft with only one engine. That means that even with a bigger engine they will not be allowed to carry more than 9 people, unless a special exception to the rule is approved for it (not really useful, also because Russia has also no available engine currently in the exact power range needed by the old an2)

    It is always better to have the capacity and not need it than to need it and not have it...

    But to get that extra capacity makes the aircraft bigger and heavier and if you almost never use that capacity, then it can be a good design choice to make it have less capacity but fully utilise the capacity it has.

    I really do think that the new IL-112 and tvs dts aircrafts will be great sellers on export market once they are for sale. Many countries have used, still using both An-2 and An24/26 and are looking to replace.

    Cheap, simple, tough, reliable... but many of those Antonovs are getting rather old and worn out.

    Ironically the best engine for a replacement of the An-2 could possibly just be a new build model of the old wright cyclone engine it used originally... produced locally under licence... It was a very simple engine that was reasonably fuel efficient but easy to maintain... they will already have plenty of spares and guys who know how to keep them running...

    Any new engine is going to be a steep learning curve and parts and spares wont be plentiful to start with...

    For their own needs, to replace these planes in Russian military service they wont want to make them super cheap, they will want better performance, but a civilian version could be developed to suit existing users perhaps even to the point where the engine can use existing spare parts...

    It is not a problem the drop in power between the an2 and the new baikal aircraft, as there are limitations in the regulations for newly built aircraft with only one engine. That means that even with a bigger engine they will not be allowed to carry more than 9 people, unless a special exception to the rule is approved for it (not really useful, also because Russia has also no available engine currently in the exact power range needed by the old an2)

    If that is the case then if they need to carry more than 9 passengers to be useful then perhaps going to a twin engine design might be the solution.

    The twin engined An-14, -28, -38, were all suggested as replacements for the An-2 at various times, but never proved as popular or cheap or as capable as the bog standard simple An-2...

    This is a bit off topic so how about we switch tacks and wonder why for a low speed drone they don't use a biplane planform...

    For loitering at medium altitude over a target area having two wings for max lift, the extra drag not critical because you want time on station and endurance rather than outright speed... An-2 aircraft are cheap right now and the engines are just AsH-62 radials... looking at the wiki page they made over 40 thousand of these engines because they were also used on the Polikarpov fighters, and it mentions in 2015 it got a fuel injection management system that improved performance and also allowed alternative cheaper fuels to be used instead of avgas...

    The extra wing volume could be used for carrying more fuel and the large lifting area means it should be able to turn well and operate over a very small area for a long period of time...

    I would think the design would lend itself well to an observation drone that carries quite a bit of ordinance available for use when needed.... an An-2 sized aircraft could have a nose mounted standard engine for takeoff and climbing, but when orbiting a combat zone it could be shut down and the main prop feathered to minimise drag and a tail mounted pusher prop of say 150hp could be run to overcome drag and maintain height and speed with a much lower fuel burn and much longer endurance...

    This is supposed to be used as a naval UAV, so it makes sense to reduce wingspan. Structurally the biplane can be interesting, but nevertheless it is more frequent to see bigger monoplane wings, maybe because they have a bigger aspect ratio and that helps with induced drag and aerodynamic efficiency in the intended flight regimes...

    Well that is a brilliant design if, as I am guessing... those big propfans rotate to allow vertical takeoff and landing...

    And those wingtips look like the fold up for compact storage on deck too... the horizontal hole in the fuselage tail area probably has a fan for yaw control at low speeds... nice...

    Fregat UAV... in general, all I see from Kronstadt looks really nice

    Is that a rotating side-looking radar? It is huge...

    There was also a video on Zvezda TV last week which showed a small SAR radar. It can be fitted to the Orlan-10 or onto the outer pylon of the Ka-52 heli.

    Is the name of the UAV in the Photoshop "Helios"?

    Do we know its characteristics?

    Manturov made a visit to Kronshtadt today:

    https://vk.com/wall-67183197_18347

    In production, we were shown the diversification of technologies developed for civilian use, technologies for creating parts for unmanned aerial vehicles (UAVs), and also presented drones "Orion", "Sirius", "Thunder", "Helios". Also, a universal ground part of complexes with UAVs was presented here: a take-off and landing control system, information processing, artificial intelligence technologies.
