The Lavochkin La-200 (a.k.a. Aircraft 200) was a two-seater,
Design and development
In response to a requirement for a high performance
The La-200 was an all-metal, two seater, twin-engined jet aircraft, with a
The main and nose undercarriages were housed entirely within the fuselage. The nose undercarriage rotated 90° to lie flat under the forward engine, and the twin wheeled main undercarriage legs, with long travel levered suspension, retracted into the centre fuselage above the forward jet pipe and astride the fuel tank and intake trunking for the rear engine.
The swept wings were of constant
The "Toriy" radar was initially fitted in an ogival radome in the centre of the air intake.
Operational history
The La-200 incorporated many innovative systems, including powered flying controls, high capacity
For initial tests the aircraft was fitted with dual controls in the side by side
To help cure the problems the starboard wing incidence was increased by 1° 30', and the twin mainwheels were replaced by single wheel units. Spill doors were fitted to the rear fuselage, arranged to open automatically when the rear engine was throttled back. The flaps and wings were stiffened, and separate aileron hydraulic actuators were installed in the wings rather than a single actuator behind the cockpit seats. Cooling air was provided for the radio which was located close to the front engine jetpipe. To address the failings of the radar, it was decided to replace it with the Korshun -(Kite) radar also developed by NII-17. The single antenna was moved to the top lip of a redesigned air intake.
By the spring of 1951 Aircraft 200 was the only one of the three competitors to survive and pass State acceptance trials. Production was provisionally ordered as the La-17, but the production directive was not endorsed so production was abandoned.
While other OKB's were designing the next generation of all-weather interceptors, OKB-301 was tasked with fitting the new Sokol (Falcon) radar into the La-200. The result was Aircraft 200B, with a new fuselage nose housing the radar behind a large radome with three air intakes surrounding the radome. By mid 1953 the radar was working adequately but Aircraft 200B's performance was no longer good enough and further work was abandoned.
