Lavochkin La-150
The Lavochkin La -150 (Russian Лавочкин Ла -150, NATO reporting name Type 3) was one of several jet fighter aircraft projects Lawotschkins that were developed after the Second World War, and benefited from experience with captured German technology.
Development
The powerplant is a Jumo 004- unit, which had been rebuilt in the Soviet Union under the designation RD -10 made use of. Because this was rather underpowered, the aircraft was easily held and practically designed around the engine around. The machine was first flown in September 1946 with test pilot AA Popov at the wheel. Five more prototypes were built, with which one tested the flight characteristics of jet aircraft at high speeds. The increased occurrence of stability defects during these experiments led to the development of the La - 150M (La -13) with a modified vertical stabilizer, a steel sheet clad tail boom and 30 ° droop wing tips. She received the equipped with an afterburner RD -10F engine as the first Soviet jet aircraft. The testing was carried out in April 1947 by Ivan Fyodorov and Mark Gallai. She reached it a top speed of 950 km / h in 5000 meters altitude.
Next, the La - 152, La - 154 and La -156 originated with reinforced hulls for experiments with different laminar airfoils. These tests were completed alternately by the test pilots Popov, Fyodorov, Gallai in the summer of 1947. In contrast to La-150/La-150M these aircraft were mid-wing monoplane. Overall, about 15 La -150 were built until La -156. Based on the outcome of tests, it was decided next to develop models with swept wings, which led to the construction of the La -160.
Technical Description
The La-150/150M was a cantilever monoplane ( La-152/154/56 mid-wing ) in all-metal construction. The fuselage had a central air inlet and equipped with a tail boom so that the hot exhaust gases could leak undisturbed. The tail unit was running unsupported and in normal construction. The tricycle landing gear was fully retractable, the main wheels were laterally retracted into the fuselage.
