The Yakovlev Yak-201 ( russian Яковлев Як-201 ) was a project for the development of the supersonic-capable VTOL - combat aircraft Yak-141 and the project Jak-43 . The concept was drawn up on its own initiative by OKB Jakowlew in the mid-1990s.
history
The design was launched in the mid-1990s on the initiative of those responsible at the Yakovlev design office. After the development of the Jak-141 and the stop of the Jak-43 project, the development of a new vertical take-off aircraft began with the Jak-201. The Jak-201 should differ from the Jak-141/43 by a larger radius of action and stealth ability . In 1996–1997, the aircraft was offered to the Russian Ministry of Defense, but the project was not taken, mainly for financial reasons and due to the Defense Ministry's lack of certainty under the LFI program. The Jak-201 is only a draft. Only a 1: 1 mock-up was built.
construction
The aircraft was designed according to the scheme of the Jak-141 and Jak-43. An elevator and rudder were attached to each of the two tail girders . In between would have been the thrust vector nozzle of the combined marching and lifting engine, which could be swiveled downwards by 90-100 ° . Both a rectangular and a round nozzle outlet were considered. In the aircraft, a single hub fan should be used behind the cockpit with mechanical propulsion via a shaft powered by the main engine. The ability to change the thrust vector would have made the aircraft very maneuverable. In the bow area only the radar and the generously glazed cockpit and the single-wheel nose landing gear were arranged. Other components such as the avionics or the GSch-301 on- board cannon were located behind the hub fan for reasons of focus.
The aircraft was designed for one pilot. Although the final engine version was not defined, the aircraft should reach an approximate speed of 1250 km / h near the ground and at an operating altitude of 1800 km / h. The projected service ceiling of the Jak-201 was 15,000 m.
Technology transfer
The thrust vector nozzle and the vertical flight control of the F-35 had been developed with the help of Jakowlew on the basis of technologies of the Jak-141. Lockheed Martin had agreed a collaboration with Jakowlew in 1991, which lasted until 1997 and financed the further development of the Jak-141. In a sense, the Lockheed F-35 can therefore be seen as a modified, realized version of the Jak-201.
