Yakovlew Yak-41M Freestyle
About this creation












The Yak-141M project started In November 1973. It’s predecessor, Yak-38 didn’t live up to expectations, in fact it’s abilities were miserable. The future fighter was design around (specially ordered for this plane) lift/cruise engine Soyuz R-79V-300. On 26th June 1974 project was officially started. At first, designers wanted R-79 to be the only engine of new fighter, but quickly it became clear, that the plane would not be able to balance in hover mode. After many experiments with different configurations, designers revert to Yak’s-38 powerplant layout, with one main lift/cruise engine and two lift engines only for hover mode. The two lift engines were Kolesov RD-41 turbojets. The final design, was finalized in July 1980. Whole project had many delays, especially there were problems with R-79 engine – it was supposed to be the first engine in the world, to be capable of afterburner usage in both horizontal and vertical thrust mode. To enable the plane vertical takeoff, engine was capable of thrust-vectoring up to 95 degrees- solution used here by designers was for years a secret, and today F-35B is using exactly the same idea. General layout of new fighter wasn’t a revolution, it’s similar in general shape to the Mig-25 – Yak-141M was originally projected to be an interceptor, similarly to Foxbat. As a carrier fighter, Yak featured folding wings. The airframe was mostly made of composites (26% of aircraft weight) and . However in the mid 80’ Soviet military changed their requirements- they wanted Yak-141M to be a true multi-role fighter, what resulted in big changes in aircraft systems. Yak-141M used S-41M radar, it was a derivative of N001 Zhuk radar, used in Mig-29M. It was a multi-role radar, that permitted the fighter to carry , new advanced missiles, both air-to-air and air-to-ground. The airframe was ready in late 1984, but due to engine problems, the first flight took place on 9th March 1987. After another period of engine/airframe problems, in 1989 began manufacturer’s flight tests. Yak-141M hovered for the first time on 29th December 1989. The tests showed, that Yak-141M with full ordnance load, clearly outperformed the Harrier in similar configuration. However in clear configuration, there wasn’t a clear-cut winner. Yak-141M was viewed, as a replacement for Yak-38, on Type 1143 aircraft carriers (Novorossiysk, Minsk Baku (Admiral Gorshkov) and Kiev). On 26th September 1991 Yak-141M made its first landing on carrier. The same day, another prototype, made first, fully vertical landing. On 5th October prototype “77 Yellow”, during vertical landing, fell onto the deck and burst into flames, pilot ejected safely. Although the trials were resumed, with “75 Yellow”, this crash served as a pretext for ending Yak-141M project. Due to collapse of Soviet Union, Soviet Navy had to make cutbacks, and Yak-141M was one. In fact it wasn’t needed anymore: Russia scraped three Kiev-class carriers: Novorossiysk, Minsk and Kiev. Fourth one, Gorshkov was later sold to India. Without suitable carriers (Kuznetsov was able to carry more capable Su-33), Yak’s fighter lost it’s sense. Yak-141M was displayed at Farnborough 92 and MAKS 1991 and 1993 airshows, for few years Yakovlev tried to attract foreign investors but without success. Yak-141M in 1991 established many world records (taking them from Harrier) in its class. There were projects of new versions of Yak-141M, but none of them become real.

Nice work! Not many people know that this served as an aid in the development of the X-35. Nice work recreating the shape. Peace ~ Packie
