T
he first jet fighter of the S.A.Lavochkin bureau. The La-150 had a straight shoulder wing. The engine intake was in the nose, the engine outlet ended after the wing, below thin tail, to reduce trust losses. Pilot was almost mounted on the engine.
Flight tests of the experimental La-150 and pre-production La-150M took place almost simultaneously in September 1946. First flight was performed by A.A.Popov. Tests continued until April 1947 by I.E.Fedorov, M.L.Gallai, N.I.Zvonarev and A.G.Kochetkov.
Small batch of La-150's was built, five of them were prepared for military parades November 7 1946 (cancelled due to bad weather) and May 1, 1947. It also was demonstrated later on Red Square parades and Tushino airshow (August 3, 1947).
General performance was satisfactory. High speed vibrations, too rear center of gravity, Pilot's cabin was too tight and fuel capacity was very small - only 553kg. TTKh (see bold numbers in the table) were not achieved, aircraft was not suitable for mass production yet.
More than five built.
