The Lavochkin La-160 Strela ( Russian Лавочкин Ла-160 Стрела , German arrow, NATO code name Type 6 ) was the first Soviet jet aircraft with swept wings.
development
The work began in 1946 by evaluating captured German research documents. The 35 ° arrow wings were attached to a La-152 cell, whereupon the fuselage had to be lengthened due to the shift in the center of gravity. The tail unit was also swept. The drive was the RD-10 engine , a replica of the German Jumo 004 unit. Since this turbine was relatively inefficient, OKB Merkulow developed a suitable afterburner. The resulting combination was named RD-10F . The La-160 made its maiden flight in July 1947 and was presented to the public at the air parade in Tuschino on August 3, 1947. The flight tests were carried out from October 1947 to spring 1948 by test pilot Iwan Evgrafowitsch Fyodorow , among others , who for the first time reached more than 1,050 km / h at an altitude of 5,700 m. In the course of further tests, the La-160 provided important insights into aerodynamics at high speeds and the static structure of swept wings, which were used in the development of more modern aircraft types. The two boundary layer fences used for the first time on the La-160 and the swept wings were added to the development program for the MiG-15 that is currently being developed . Although the "Strela" was not built in series, it was used to train selected pilots in order to get them used to the propellerless jet aircraft. A version with a Derwent engine planned by Lavochkin was not approved.
