Yakovlev Yak-43
The Yakovlev Yak-43 was a Soviet VTOL (vertical takeoff and landing) fighter designed as the ground-based version of the ill-fated Yakovlev Yak-141, which failed to reach production. Like the Yak-141, the Yak-43 did not reach production.Gunston, 1997 The Yak-43 would have been the third-generation VTOL/STOL fighter, to follow and eventually replace the Yak-141.Gunston, 1997 Design and development Like the Yak-141, the Yak-43 would have had only a single main engine, as well as two dedicated vertical-lift engines. The main engine would have been based on the Samara NK-321 three-shaft augmented turbofan with a takeoff rating of . This same engine is used to power the Tupolev Tu-160 Blackjack bomber. The engine would have had a large air bleed leading to an auxiliary combustion chamber located in the nose, though a separate lift jet would have been retained.Gunston, 1997 A new integral layout use stealth technology which is a single whole of the fuselage with the wing.

VSTOL
A vertical and/or short take-off and landing (V/STOL) aircraft is an airplane able to take-off or land vertically or on short runways. Vertical takeoff and landing (VTOL) aircraft are a subset of V/STOL craft that do not require runways at all. Generally, a V/STOL aircraft needs to be able to hover. Helicopters are not considered under the V/STOL classification as the classification is only used for aeroplanes, aircraft that achieve lift (force) in forward flight by planing the air, thereby achieving speed and fuel efficiency that is typically greater than the capability of helicopters. Most V/STOL aircraft types were experiments or outright failures from the 1950s to 1970s. V/STOL aircraft types that have been produced in large numbers include the F-35B Lightning II, Harrier, Yak-38 Forger and V-22 Osprey. A rolling takeoff, sometimes with a ramp (ski-jump), reduces the amount of thrust required to lift an aircraft from the ground (compared with vertical takeoff), and ...

Yakovlev Yak-201
The Yakovlev Yak-201 was a planned Russian vertical takeoff and landing stealth fighter/ interceptor aircraft for the Russian Navy, as a follow up to the Yak-141 and Yak-43 aircraft. The design was carried out in the mid-1990s Yakovlev Design Bureau. The project was cancelled and no prototype was built due to a lack of funds and interest by the Russian Ministry of Defense. Development The design was started on an initiative basis by the Yakovlev bureau officers in the mid-1990s to allow the Russian Navy aircraft carriers to operate state-of-the-art vertical takeoff and landing aircraft. After the Yak-141 and Yak-43 were developed, the engineers from the Yakovlev Design Bureau proceeded to the Yak-201. In 1996–1997, the aircraft was offered to the customer, but the project remained unclaimed, primarily for financial reasons, and also due to the lack of certainty of the Russian Ministry of Defense under the LFI program. No full size mock-up nor prototype were built. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
