Along with the Alouette III, the Cheetah was a key product for HAL; experience from manufacturing the type aided in the later development of more advanced indigenous helicopters such as the HAL Dhruv. [5] During the 1990s, HAL developed an armed light attack helicopter based upon the Cheetah, which was given the name Lancer. [6] [7]
The Lancair 200 was initially called the Lancer 200, but the name was changed due to a naming conflict. It was first shown at AirVenture in Oshkosh, Wisconsin in July 1985. Now out of production, when it was available the aircraft was supplied as a kit, for amateur construction.
In early 2017 the company, including all the older aircraft designs, was sold and moved from Redmond, Oregon to Uvalde, Texas under the name Lancair International, LLC. The newest model, the Lancair Evolution was retained by the existing company, Lancair International, Inc, which changed its name to the Evolution Aircraft Company.

Since the Northrop F-5 was named the winner in November 1970, the primary market for the Lancer was lost, and the project was terminated with no aircraft completed. The X-27 was an experimental designation assigned by the USAF [1] to a proposed high-performance research aircraft derived from the CL-1200 Lancer project. The X-27 was to have ...
Proper maintenance of the helicopter's damping system components can prevent ground resonance from taking hold. When it does occur, recovery is often possible if action is taken quickly. If sufficient rotor RPM exists, immediate takeoff can restore rotor balance by allowing the airframe to move and help dampen the oscillation freely. [ 1 ]
[1] [2] Unlike fixed-wing aircraft, of which the stall occurs at relatively low flight speed, the dynamic stall on a helicopter rotor emerges at high airspeeds or/and during manoeuvres with high load factors of helicopters, when the angle of attack(AOA) of blade elements varies intensively due to time-dependent blade flapping, cyclic pitch and ...
TSR-2 XR220 at RAF Museum Cosford, 2002. Ferranti developed the first terrain-following radar specifically for the TSR-2. Terrain-following radar (TFR) is a military aerospace technology that allows a very-low-flying aircraft to automatically maintain a relatively constant altitude above ground level and therefore make detection by enemy radar more difficult.
