    Some recent photos of the Yak-152 doing flight testing. Nice shot of the -152 sitting beside a Yak-52 which it replaces.

    i dont think this airplane engine is good choise for russia, air cooled is better then water cooled in freezing russian weather, maintenance is easier , damage tolerant ,and heats up faster.

    When compare data sheet of two engine versions of Yak-152, I see the Yak-152 with RED diesel engine has max range of 1,500 km while max range of the Yak-152 with M-14X radial engine is 1,000 km. Both of them use iternal fuel only and suppose they have the same internal fuel weight of 200kg. Does RED engine really save fuel more 50% than M-14X?

    I can well believe it.
    Years ago when Zoche was touting their aero diesel, one of the main selling points was that it was so much more efficient than many older aero engines.
    They had been touting their diesel at the general aviation market, where there are tens of thousands of planes equipped with radial/piston Continental and other engines of about 360hp and under.
    They were reckoning an improvement in range of between 50% to 80%, depending on type. The upper % figure is basically almost a doubling of range.
    And it isn't only its efficiency...it's the availability of avgas that is also an issue, with seperate delivery, storage, and pumping facilites required.
    Diesels run on jet fuel, and indeed, on a wide variety of fuels.
    I recall reading many years ago that many of the more popular/best selling light aviation piston engines are actually quite elderly in their design origins.
    It is amazing to think that the M-14, Continental O-300, and Lycoming O-320 are all designs originating from the 1940's and 50's, or between 65 to 75 years ago! Obviously they have been updated, but that fact remains.
    Many companies have been looking at aero diesels again in the last decade or two, among them continental itself, which has licenced a French aero diesel design.
    The Germans were big pioneers in the aero diesel field in the 30's and 40's in particular, with various airship and long range aircraft and flying boats powered by them for the good reason of their excellent fuel efficiency. They were used in combat too.
    For example, the B&V Ha139 was used to deliver mail across the Atlantic on 5000km flights.

    I think the diesel on the Yak-152 is a good idea.

    About training aircraft Yak-152



    The magazine «Air & Cosmos» published an article by Peter Butovo (in collaboration with Antony Angrand) "Premier vol du YaK-152", which provides some additional details of the program of development of the new Russian training aircraft initial training Yak-152.

    So, it is reported that various motors can be mounted on the Yak-152. Option for FSI six-cylinder diesel engine equipped with Russian A03T 500 hp, produced by RED Gmbh. To do this, the engine is a three-bladed propeller MTV-9-E-C. Another engine option may be a reciprocating engine OEDB M-14X power of 360 hp, which is used in Chinese training aircraft Hongdu L-7. The other two options can act diesel engine RED A05 300 hp Ukrainian and turboprop engine AI-450 (450 hp). The maximum fuel capacity is 175 kg of kerosene or other liquid fuels.

    According to the requirements of the Ministry of Defense of Russia, on the plane must be installed cockpit, similar modern aircraft, standing on the arms, and the Yak-152 is to teach the necessary skills with the purpose of better development of combat training aircraft Yak-130. In an embodiment, a light combat aircraft Yak-152 with engine RED A03T can carry up to 550 kg payload on four pylons. It can be NAR blocks, bombs, guns, or "air-to-air" missiles.

    The program itself was launched in 2001 to replace the Yak-52 aircraft, whose concept leaves in 1970. Two projects have been put forward - the Yak-152 and Su-49. The choice was stopped on the latest version, but the aircraft did not perform a deep study of the project.

    Therefore, the new tender was announced in 2007, this time within the framework of UTC TNG (The training complex initial training), but he had no success. At this time, the Yak-152 was created in accordance with China's needs. Under the contract, signed in June 2006, Yakovlev Design Bureau used for the development of the Yak-152 project of AVIC Hongdu L-7 (CJ-7) "Cadet / Sokolik", equipped with a piston engine. L-7 prototype was presented at the air show in Zhuhai in November 2010. However, the state of the Chinese program is unknown. The plane made only one flight and is currently undergoing static tests.

    UTC PNP program continued under the code name "Bird-Air" aircraft full-scale mock-up was approved by the Commission of the Ministry of Defense of Russia on December 23-25, 2014. The contract should be built two prototypes and two fuselage for static tests. Deputy Defense Minister Yuri Borisov in September 2015 stated that the Ministry of Defense plans to buy 150 aircraft of this type. And in June 2015, Deputy Director of Aviation Department - Head of the flight activity DOSAAF Andrei Lebedev said that DOSAAF intends to purchase 105 aircraft until 2020.

    There are some mistakes about RED engine. The RED A03 is V12 engine while the RED A05 is V6 and its max power is 350HP, not 300HP.

    New take-off magazine issue
    http://en.take-off.ru/index.php/component/content/article/45/431

    Just downloaded and quickly read. I am so confusing about the final chosen engine for Yak-152. In the magazine they said the final chosen engine will be RED A03 V12 500hp and optional RED A05 V6 350hp instead of M-14X engine that has been stopped producing. However many sources recently claimed that the sanction and the priority using domestic products made 150 Yak-152s that orderred for Russian AF changed their engine from German RED A03 to domestic M-14X.

    So which one is the latest and updated news?
