Lavochkin La-200
The Lavochkin La -200 (Russian Лавочкин Ла -200) was a Soviet fighter plane, the end of the 1940s, was developed and tested in the early 1950s by Lavochkin, but not went into production.
History
The Lavochkin OKB received in 1949 in addition to the design offices of Mikoyan, Sukhoi and Yakovlev the contract for the air defense of the USSR to create a twin-engine all-weather long-range interceptor.
Thus, the La -200 was built with swept wings and a central air inlet, whose center was the radio measurement visor Thorium -A under a disguise. To obtain the lowest possible resistance front, the two jet engines were arranged in a most unconventional way after the other: one in the bow with the corresponding exhaust nozzle under the bow and one in the rear fuselage; the advantage of low brow resistance but was bought with an unnecessarily complicated air supply duct for the rear engine. The crew sat side by side in a pressurized cabin. The first, La - 200-01 prototype called, took on 9 September 1949, the Test Pilot Team S. F. Maschkowski and A. F. Kosarew flight testing on. The tests lasted until October 1950 and were also completed with a designated as La 200-02 second machine in which they had moved the radio meter from the center of the air intake duct to the top.
The Scientific Institute of the Air Force had now issued a revised specification in which a greater range was required for both the aircraft and the replacement of the built-in radio measurement visor thorium, which is now being developed newer Sokol, which is why from April 1951 planned series production of the La - 200 in the first embodiment, did not materialize. Subsequently, the model has been revised because the air intake had to be completely redesigned for the engines due to the now larger parabolic antenna of the radio instrument. To the lining of the Sokol were now bottom and sides of three Luftansaughutzen grouped, the lateral sticking out of the fuselage contour and the rear engine -powered, while the lower inlet for the front engine was. The cockpit has been redesigned and the machine received great droppable auxiliary tanks.
The resulting aircraft was designated La -200B and was introduced on July 3, 1952 by Andrei Kochetkov in the factory testing, which was completed in September. The state test series began in April 1953 and only now noticed you the possibility of errors on the drive of the hydraulic flaps which could be solved, however. In mass production, the La -200B was not transferred because they did not reach the one hand, the required coverage, on the other hand, the completion of the new Sokol radar further delayed. Then served but for a time as a flying testbed of this device, which was eventually incorporated into the Yak- 25, which already belonged to the modern generation of Soviet fighter planes.
