A miniature “friend or foe” system has been created to identify drones
29.11.2023
A new small-sized transponder for identifying drones, presented at the Electronics of Russia exhibition by the Ruselectronics holding, is capable of revolutionizing the unmanned aerial vehicle industry. The device, developed by NPP Pulsar, operates on the “friend or foe” principle and automatically marks friendly UAVs at an altitude of up to 5 km and a distance of up to 100 km from the radio interrogator. This was reported in the press service of the holding.
One of the key features of the innovative miniature device is its ability to work with the Russian Password identification system. Such devices are widely used in aviation to identify differences between their own equipment and that of the enemy. With the development of unmanned aircraft systems and the presence of a large number of them in the zone of a special military operation, there is a need for devices that can determine the identity of the UAV.
The identification device is designed taking into account the requirements for mobility and versatility. Its light weight, not exceeding 150 grams, and low power consumption of 100 mV allow the device to be integrated into a wide range of civil and special-purpose drones, such as reconnaissance ones. This opens up new opportunities for the use of drones on the battlefield, where they serve as fire spotters, as well as surveillance and fire weapons.
General Director of NPP Pulsar Sergei Borovoy emphasized the importance of such identifications in modern conflicts, where both sides often use the same models of drones. This makes their visual identification difficult - often in the reports of Russian military officers, soldiers on the front line note that they hear a drone, but it is impossible to understand whether it is one of their own or someone else’s.
The use of a new identifier will make it possible to reliably distinguish the identity of a UAV, which will increase the efficiency and safety of the actions of Russian units.

If you watch carefully there is another helicopter drone with a four tube rocket pod mounted on the wingtips that appears to be able to be aimed up and down and I think I saw a spec sheet showing the four tube launcher was 57mm calibre. Edit: It called them unguided 57mm rockets with a range of 1.8km so they are just dumb unguided rockets for direct fire at targets.
If they have laser guided S-8 rockets that really would make these helicopter drones rather potent... on one of the spec sheets for the model with two four tube 57mm unguided rocket pods on wingtips it also mentioned a 7.62mm machine gun with 550 rounds of ready to use ammo... for use out to 1.5km, these things are getting more fun all the time.
The guided 80mm rockets could take out vehicles of all types with precision at 6km range, which is pretty much out of return fire range for most weapons, while the 57mm rockets could be used to hit enemy troops in bunkers and would probably be fired at targets at 1-1.5km where the machine gun would also be effective too...
With thermals they will be fun during winter.
For example, the American Institute for the Study of War, having analyzed available videos, believes that Russia has managed to create a “swarm of drones” capable of exchanging information and using artificial intelligence to independently determine targets.
also to add we had news reports like 2 weeks ago of new 80mm rockets in development of new highly efficient engines that might push the range farther than 6kms to maybe ranges passed hellfire missiles.

I am sure both versions will be produced and used.ALAMO wrote:Yes and no.
It will be 3x faster indeed, but now it will be possible to lock on with MANPADS.
It was Geranium advantage - no MANPADS in Ukro hands could effectively engage it, as there was almost no heat emission.

“An alternative to imported supplies”: Russian developer talks about new piston engines for small aircraft and UAVs, by Alexey Zakvasin and Dmitry Strakhov for RTRussian. 12.19.2023.
The developer told RT about new piston engines for small aircraft and UAVs.
By the end of the year, scientists from the Ufa University of Science and Technology (UUNiT) will produce a prototype of the DDA-160 aviation piston engine, designed to replace the popular Austrian Rotax. Doctor of Technical Sciences, Professor, Head of the Department of ICE (Internal Combustion Engines) Rustem Enikeev stated this in an interview with RT. According to him, the domestic unit should surpass its Western competitor in power and efficiency. The DDA-160 will lift large UAVs and small aircraft into the air. In addition, in 2024, the Ufa university, together with the Skolkovo resident “Engines for Aviation,” plans to launch mass production of four-horsepower piston engines, which were not previously mass-produced in Russia.
— When was the last time Russia produced a full-fledged piston engine for small aircraft?
— Still in the Soviet Union. These were engines of the ASh series of the Perm Design Bureau of Arkady Shvetsov for the An-2, as well as the M-14 engine manufactured in Voronezh - it was installed on the An-14 aircraft. Small engines for unmanned aircraft were created in Samara. In general, all this happened several decades ago, when the country had a developed aviation piston engine industry.
— Why does the country need a new piston engine, and not a gas turbine engine, which is mainly used by
aviation?
— In fact, we need different engines: gas turbine, piston, and electric. When we talk about civil aviation, we usually imagine airliners that can take us from Moscow to Beijing.
In the 1940s and 1950s, aircraft designers immediately switched large aircraft to gas turbine engines, which gave an incredible leap and surpassed their piston counterparts in power. In fact, there are small aircraft left that still fly on piston engines all over the world. They consume less fuel, cost much less, and are easier to maintain.
In the power range around 400 hp. With. the piston unconditionally outperforms the gas turbine. If we take it higher, then competition begins between them.
— What was the situation in the field of piston engine manufacturing in our country after the collapse of the
USSR?
— For the last 30 years, research and development have continued in scientific structures, design bureaus, and specialized universities.
In Russia there are now several crystallization points where engines are born, and we are only one of them. At our university, this work was initiated 25 years ago by Professor Boris Petrovich Rudoy, head of the department of internal combustion engines (ICE), my teacher and scientific supervisor. We continue the developments he started; the scientific team includes doctors and candidates of science, graduate students, master's students, students of UUNiT and even schoolchildren.
— When creating motors, did you initially think about which models they could be installed on?
“We worked for a long time without any specific connection to the aircraft. In general, this is wrong, since no one needs an engine as such, it should always be a part, the heart of a certain machine.
Unfortunately, until recently, our developers from the aviation industry did not show serious interest not only in us, but also in Russian ICE designers in general. They flew on engines of German, Austrian, Japanese, Australian, and American production. The attitude towards us was something like this: don’t stop us from flying on foreign engines. Although we knocked on many doors (including high offices) and said that the situation is bad: Russia does not have its own aviation piston engine and any disruptions in supplies will lead to small aircraft being left without wings.
— What has changed after 2022?
“We are now working closely with manufacturers and developers of aircraft—a wide variety of aircraft—to adapt our prototypes to their tasks. This is a very significant turn, because interaction with aircraft designers has been established and our models already have a specific purpose.
— What power are your engines and what do they run on?
— We have several lines of aviation piston engines with power from 4 to 220 hp. With. Each of them is in varying degrees of readiness - from drawings to a prototype. Some of our engines run on gasoline, others on kerosene.
We took kerosene into account when developing the engine, since aviation in general is highly dependent on this fuel, and building logistics taking into account only gasoline alone is irrational, and sometimes even completely unacceptable.
We were able to launch the workflow using aviation kerosene, but this is a problem for many scientists and designers. As a rule, they solve it by using diesel engines, achieving fuel efficiency, but losing to the gasoline version in terms of specific power.
Of course, today there are good Austrian and German diesel engines that can run on aviation kerosene. European engines are created using advanced technologies and modern materials, but they are too expensive and heavy.
- For which aircraft is your most powerful engine designed - 220 hp? With.?
— The DDA-160 engine is an engine with a volume of 1600 cubic centimeters. It will be presented in a kerosene version of 170 liters. With. and gasoline - in the range of 190-220 liters. With.
We created this engine as an alternative to the Austrian Rotax - a world classic, which is often used on American, European, Turkish UAVs and small aircraft. In Russia, these motors are used on sports and even homemade vehicles. However, it is almost impossible to buy a Rotax in our country today.
DDA-160 is more powerful than the “Austrian”, more economical and cheaper. The prototype gasoline engine is 60-70% complete. There are still difficulties with the remaining components, but we plan to assemble a prototype by the end of the year and put it on a test stand.
— Is UUNiT developing “pistons” of lower power?
— One of the Ufa models is a two-stroke single-cylinder liquid-cooled engine APD-200 with a power of 32 hp. With. This is a 200cc engine. cm. It is manufactured according to aviation regulations, but is now being tested on sports cars - this way the engine runs hours in real operation, and not just on a stand.
To date, the APD-200 has worked for about 300 hours. In terms of external speed characteristics, this is a lot, and the engine has proven itself to be reliable. Tests on the ground will continue for months and will provide even more information about the capabilities of the motor.
After this, we will be able to offer a prototype to aircraft developers. I think that in the future the engine will be in demand both in motorsport and in aviation.
We proceed from the fact that the aviation industry needs engines with the highest possible power and minimum weight. The same APD-200 just meets these requirements.
Also, our specialists are now coordinating the terms of reference for an engine for their aircraft with a potential customer. One of them is an unmanned civil helicopter for transporting goods. It will receive a V-shaped four-cylinder two-stroke gasoline engine with a capacity of 108 hp. With.
The motor will be able to lift loads of several tens of kilograms into the air. Its key feature is that it will be made on the basis of an engine already mastered in production by the Russian Mechanics company (Rybinsk). Our customer has a serious business of delivering cargo by drone throughout the country, including in the North.
— When do you think Russia will begin mass production of piston engines to meet the demand of UAV and light aircraft manufacturers?
“I think it will happen soon enough.” As for our engines, we have developed as a scientific school, creating new solutions and prototypes. However, now we have gone further and finally started interacting with end consumers.
There are chances that in 2024 our two-stroke kerosene engines DDA-4D and four-stroke gasoline engines DDA-4CH in 4 liters. With. will be the first to go onto the assembly line. Such light but powerful engines, as far as I know, have not previously been mass-produced in Russia.
The country really needs these “pistons”; many UAV manufacturers are waiting for them. The most popular aircraft-type drones fly on similar engines - drones perform various tasks: geodetic surveys, pipeline inspections, aerial photography. I am sure that in the next year or two our other colleagues will shoot with serial piston aircraft engines and offer a worthy alternative to imported supplies.
“Russia today also needs military drones. Can your motors lift them into the air?
“There are drones that take off from your hand, and there are huge devices that can only be lifted by a powerful motor. We work with Russian companies that need motors for civil UAVs. And so we are open to any cooperation. I can only say that the well-known Geranium, judging by open sources, flies on a conventional 50 hp piston engine. With. This figure fits into the range of our motors.
—Your university does not have production facilities. When you need to launch a conveyor, where will you produce engines?
— We have a long-standing and key partner - the Skolkovo resident “Engines for Aviation”, who participates in both development and production of prototypes. By the way, the name of our flagship engine DDA-160 comes from it. The company is located next to us, in Ufa, and we expect that we will mass-assemble jointly developed engines at its facilities.
— Are the developers of “pistons” ready to help in the development of small aviation in the Far North?
— Russia still lags behind other aviation powers in the development of small aviation. In Canada, Alaska and the Nordic countries, communications with remote areas are provided by light aircraft. There the sky is the road. You look up and something is always flying.
I think this is the path of Russia, which vitally needs to develop the Far North. And for this we need different aircraft: two-, four-, eight-seater, unmanned. And each requires a piston motor. In my opinion, Russia is gradually coping with this task.
