In may, scientists at the Central Aerohydrodynamic Institute have completed the first stage of the research model promising short-haul aircraft.
The aircraft is to feature 2 main novelties...
The first innovation specialists TSAGI is a wing of low sweep, allowing to provide laminar flow, in which there isn't chaotic velocity pulsations and the surface pressure significantly decreases the resistance of the aircraft. The use of modern profiles allowed to keep the same speed as its predecessors — 830-850 km/h.
The second distinguishing feature of the new aircraft is the location of the engine over the rear edge of the wing - as a noise reduction measure
Interesting, I wonder if this would be the "new" "not-stretch-of-SSJ" 130-seater I had seen mention of... The over-wing engine has many more benefits than just noise reduction, besides facilitating larger fans and short/light landing gear, I believe there is also some aerodynamic efficiency benefits, or at least HondaJet touts that about their small bizjet of similar config...
Curious how this concept/project impacts potential SSJ developments, i.e. re-engine/re-wing/stretch/shrink/etc... Plausible that only small changes to SSJ will be pursued in short term (add a few frames, tweak existing engine, easy aero tweaks), but hold off on new wing, engine, until new 130-seater is done and it can either be shrunk or those elements "ported" to SSJ...?
That sort of engine location has been tried on the AN-72 and while found to be efficient in terms of flight and takeoff performance, it makes the engines very hard to service... perhaps a walkway building into the wing structure with access via roof hatches in the fuselage would enable maintainence at airfields not equipped with cranes or raised platforms...
The first medium-range passenger aircraft MS-21, which will be operated under the name of the Yak-242, will rise into the air in June 2016, said on Thursday Deputy Prime Minister Dmitry Rogozin.

Not quite sure what you mean by the bolded (were you thinking of roof hatches in the context of high-wing An-72?), that sounds tedious vs. existing over-wing emergency exits, though I wouldn't expect even those would be used because of hassle of entering plane and carrying tools thru, etc. I just don't think the rough-field maintenance (or even operations) you seem to be imagining are a design factor in ANY civil jetliner of this size nowadays.
Nacelle access via step-ladder and standing on wing does seem plausible enough, or else with hydraulically raised walk-ways... For engine removal I would guess that a standard fork-lift could be trivially adapted, if not a customized hydraulic engine cradle (which are used on larger engines now) Any location that has qualified staff to work on the engine will have the tools they need as well, so if it is forced to make emergency landing at unprepared field, it will wait for repair team+gear to be delivered, just like the other civil airliners it is meant to compete against...
Ultimately, where else are they going to get the aerodynamic, ground noise, and fan-size benefits this enables? Obviously the maintenance procedure will need to be tweaked vs. low-mount engines (likewise for HondaJet), but I hardly see that costing enough to out-weigh the benefits.
Anyhow, the point about enabling larger fan sizes in this segment of civil airliner obviously points to Geared Turbofan developments...

The roof hatches were in context of the An-72.
In terms of this new aircraft they should make clearly marked areas from the fuselage where technicians can walk on the wing so they can walk on the wing around the engine... a major part of the success of the podded engine design used around the world on civilian airliners is their ease of access to the engines... putting them on top of a wing makes access harder... as I said with the example of the An-72... there were plenty of good reasons for putting it there in terms of thrust and lift and drag, but the current development of the An-72 is basically called An-148 and is pretty much just an An-72 with pod mounted engines to ease maintainece access.

There are plenty of airfields around the world still where hydraulically raised platforms are simply not available. Being able to access the engines from both sides by being able to walk on the wing is all I was suggesting.
Ultimately, where else are they going to get the aerodynamic, ground noise, and fan-size benefits this enables? Obviously the maintenance procedure will need to be tweaked vs. low-mount engines (likewise for HondaJet), but I hardly see that costing enough to out-weigh the benefits.
I am not saying it can't be done... I expect their experience with the Coaler will be used in the formulation of this design...
KRET creates avionics for MS-21 airliner together with the Israeli company
WTF ?
http://tass.ru/armiya-i-opk/2023130
MOSCOW, June 5. /TASS/. The specialists of the concern radio-Electronic technologies (KRET, part of rostec) has discussed with Israeli partners from Elbit Systems ("Elbis systems) implementation of joint development of multifunction indicator for the MS-21 airliner, announced on 5 June at the press service of the concern. The Israeli side, said KRET, supplies Ulyanovsk instrument design Bureau computing module, which is part of the indicator. "The meeting was devoted to debugging of equipment and preparation for the start of mass production of modular avionics segments for the MS-21. It is important to compare notes before the beginning of a new phase of integration of the production, which will begin in June this year", - said the chief designer of the Bureau Alexander Vinogradov. The Ulyanovsk enterprise is developing a control system aircraft equipment SOSO-MS-21, a system for measuring air data SIVD-21, as well as indicators and remote controls integrated avionics system, which ensures the creation of a single information-control field of the cockpit. In the creation of medium-haul passenger aircraft MS-21 is attended by about 100 Russian and international companies. KRET, in particular, delivers up to 80% of the avionics. It is expected that the first flight of the airliner will make in 2016, and mass production will begin after 2020.
I would leave sponsoring of Israeli industry to US Keeping traditions is very important ). Russia should stick to import from Israel Jaffa oranges or onions.
Boycott the terrorist nation at all costs, period. Not to mention that it is right out hilarious and stupid at the same time to corperate with Israel on Aviation, since all their scientists were mostly from Soviet Union, so russia is corporationg with its own ideas and build up intellectual workforce... reminds me what we are doing here in germany. Bundeswehr builds up facilities and military bases, sells them after few years and then rents the place for decades while paying to private companies millions...that is what that is.
If the alternative is to cooperate with Europe or the US then I would say cooperating with Israel is fine on civilian aircraft... though that might lead to issues with some potential clients... hopefully there is an all russian Avionics version in that regard....
If Israeli technology will make the MS-21 more competitive than I'm all for it.
The Sukhoi Superjet involes a whole bunch of companies from all over Europe, the countries of some of which have worse relations with Russia than Israel has with Russia right now.
No-one's boycotting or sanctioning the Superjet, although I suspect it's a possibility if things keep going south. Therefore it makes sense to weave away from European suppliers and partners, and onto those from other countries. Those other countries can include other US allies too; but that Russia has good relations with - such as South Korea, Japan, Turkey, UAE, Jordan and Israel.

The Superjet has been very successful with its only Western customer, Mexican Interjet, which praises its high reliability (a bit higher even than the Airbus 320, Mexican pilots call it "el tanquito", "little tank"), fuel efficiency, and good hot-high performance. I guess what is preventing other airlines from ordering it is fear of an escalation of Western sanctions that may target this aircraft.

and Indonesian Sky Aviation. I mean contracts inked not options. China is in talks with Russia about 100 Superjets. If India will be next customer then SSJ has nice future.
Draft organization of serial production of Il-114-300
The business plan of the project "Organization of serial production of Il-114-300 at the industrial site of "Aviacor-Aviation Plant "(Samara) in broad cooperation with the enterprises of RAO "KLA" and of "UAC" posted on the website of the Tyumen MTU FATA.
The business plan has been prepared in fulfillment of a protocol meeting with Deputy Prime Minister of the Russian Federation of 10.10.2014 № RD-P7-58pr. Approved in 2014. Director of the airline business OOO "Russian Machines", General Director of JSC "RCD" and Vice-President of JSC "UAC".
The project is the organization of production of family aircraft IL-114-300 in the Russian Federation based on the following presuppositions:
• The needs of regional airlines in the Russian passenger aircraft for regional and commuter passenger capacity up to 64 people to replace obsolete fleet, especially the Yak-40 and An-24 decommissioned because of the development of resources and the replacement of aircraft fleet of foreign manufacture ATP-42; ATR-72 on the program of import substitution; • The needs of the airlines of the Russian Federation in the cargo airplane with a payload of up to 7 tons and a range of up to 1000 km; • Creation of the aircraft on the ski-wheeled chassis for operation in the Far North and Antarctica in the framework of the "Strategy of development of the activities of the Russian Federation in the Antarctic for the period up to 2020 and for the longer term", approved by the Federal Government of 30 October 2010. Number 1926 p .; • Creation of special purpose aircraft for the needs of the Russian Defense Ministry, the Federal Security Service, Ministry of Emergency Situations et al., as well as to supply to foreign customers.
The aim of the project is to start serial production of a fully localized civil regional aircraft IL-114-300 at the production site of "Aviacor Aviation" factory in Samara on the basis of modern high-performance equipment and the latest technology.
The main objectives of the project are: • Implementation of the ROC on completion of the IL-114-300 to market requirements; • Digitizing documents modernized version of the Il-114-300; • Modernization of power "Aviacor-Aviation Plant" • Training and development of mass production of IL-114-300, with full localization in Russia; • Restoring the serial production of engines TV7-117SM and works to increase resources up to 6000 hours. • Promotion of products to target segments of the domestic and world market; • Organization of after-sales service.
Characterization of the IL-114-300
IL-114-300 is intended for transportation of passengers, cargo, mail and should be used with paved runways Class A, B, C, D and GVPP with soil density of 7.5 kg / cm2 (5.5 kg / cm 2 while limiting takeoff weight), the outdoor temperature from -50 ° C to + 45 ° C. The scheduled performance should not be worse than the certified basic Il-114. The Il-114-300 applied modern Russian flight control and navigation system TSPNK-114M2. Turboprop TV7-117SM capacity of 2650 hp with low noise six-bladed propellers NE-34.03, provide high fuel efficiency and low noise levels according to international standard ICAO Annex 16 Chapter 4 as the auxiliary power unit used TA-14-114.
During operation of the lab IL-114LL in NPP "Radar MMS" was, in practice, confirmed the feasibility of creating a platform for the IL-114 family of aircraft special aviation patrol aircraft, airborne command post aircraft, and aerial photography.
IL-114-300 will have a range of up to 4,800 kilometers with a load of 1000 kg and 1000 kg to 3250 km., With a maximum fuel capacity - up to 5600 km. All fuel consumption during the flight with maximum fuel will be 550 kg / h. As shown in the business plan according to a comparison of competing transport capacity aircraft types indicates that IL-114-300 largest maximum capacity is intermediate between the aircraft ATR-72 and AN-140. The flight range of the aircraft IL-114-300 with maximum payload is comparable with the range of aircraft ATR-72 and O400. When flying at a distance of 1-3 thousand. Km mass payload aircraft IL-114-300 is almost equivalent to the specified terms of the An-140. However, on a more long-haul routes Il-114-300 is completely superior to its competitors. According to the compilers of the report, the transport capacity of the aircraft IL-114-300 fully competitive in comparison with the characteristics of the aircraft peers.
Assessment of the volume of sales of various modifications based on the Il-114
IL-114-300 is the only certified platform for the special Russian aircraft in the class of aircraft carrying capacity to 10 tons. The total market potential aircraft special modifications, created on the basis of Il-114-300, is estimated at 170 until 2030. Domestic demand for special class aircraft IL-114-300 is valued at 100 units until 2030. According to plans of the SDO in the period to 2020 the Russian Defense Ministry plans to buy 12 special class aircraft IL-114-300. Continued procurement in view of the objective needs of the Russian Defense Ministry, is expected after 2020. Potential foreign market is estimated at 60 special aircraft until 2025, and 50-70 in the period after 2025. The most likely customers in the global market may become the CIS countries, Algeria, Angola, Venezuela, Egypt, India, Vietnam, Ecuador, Cuba. Thus, according to the forecast of a moderate, shipments Il-114-300 in the period up to 2030 will be about 150 aircrafts. The total need for different versions of IL-114-300 is estimated at 228 aircraft:
State structures RF Ministry of Defense (Navy) - 35 FSB - 28 Russian Ministry of Emergency Situations - will be determined after 2015 Federal Fishery Agency - 4 OAO "Rosoboronexport" - 60 2025, 50-70 after 2025
Curious about status of PSV program, the image displayed seemed to be Mil's concept, if their design is having problems, wouldn't Kamov's pusher design be considered as alternative? Good to hear that Mi-38 and Ka-62 are still moving along, hopefully will see full production soon... I know Ka-62 had been sold to Colombian and Brazilian customers, hopefully they can fulfill those orders...
Meet Afalina: Russian manufacturer reveals the world’s cheapest helicopter
The Russian designers are about to fulfil the consumer’s dream of an affordable helicopter, with Afalina rotorcraft expected to cost about half than currently the cheapest offer on the market and run on car fuel as it goes into production in 2016.
HeliWhale, a company from the Siberian city of Kemerovo, revealed its unique helicopter at the HeliRussia 2015 exhibition, which took place in Moscow in late-May.
An ultra-light, coaxial two-seater is called Afalina, the Russian word for bottlenose dolphin, with the rotorcraft’s hull resembling the shape of the marine mammal’s body.
Afalina is designed as a multipurpose helicopter capable of performing a variety of tasks, including the training of pilots, maintenance of pipelines and power lines, aerial surveillance, police patrolling, transportation of personnel, farm work and recreational flights.
One of the machine’s key features is the customizable Enigma system, which allows the pilot to pick and choose his cockpit display layout from hundreds of devices and functions.
The coaxial positioning of rotors used in Afalina ensures that the aircraft is easier to pilot, more silent and more resistant to lateral wind gusts.
HeliWhale said that the patented new control system of coaxial rotors also provides the helicopter with high velocity of up to 250 kilometers per hour at max speed.
The aircraft, weighing 270 kilograms, is capable of carrying a payload of another 180 kilograms, the company said.
Afalina can also be refueled with conventional 95 octane car fuel, with the consumption between 12 and 16 liters (3 to 4 gallons) per hour
According to HeliWhale, the helicopter will cost $120,000, which includes heating and ventilation systems in the cockpit.
“Today nobody else produces aircrafts of this class, even the two-seater ‘Robinson’ is heavier than ‘Afalina’ and is, in fact, a completely different machine,” Jacov Kolesnikov, general director of HeliWhale told Russia and India Report website.
“The American Robinsons are also much more expensive. A two-seat helicopter costs $300,000,” he added.
Afalina has been built from scratch by the Russian designers, with HeliWhale producing all parts itself, except for the Austrian made engine, Rotax.
“We are looking for domestic engines, and if there is a quality Russian engine, maybe we'll switch to it,” Kolesnikov said.
Endurance test for the flying prototype of the rotorcraft are about to begin in short term.
The company says that its production plant in Kemerovo will be able to build from 10 to 15 machines every year.
They’ll be supplied to customers as kit-sets models for self-assembly in order to keep the price low, the developer said.
Besides Russia, HeliWhale is planning to engage with the US, Australian, and EU markets, saying that it already has orders for Afalina from abroad.

Or a safer option, such as having high-def cameras on the sides of the helicopter, pointing towards the bottom, with Plasma screens in the cockpit display showcasing what happening in the streets below.
Costs 120 grand and considered a consumer product for the future average joe?? This helo, although awesome costs as much as a fucking ferrari!! Wake me up when I can swap a ford,toyota or at least mercedes for this
