Lavochkin La-190
The Lavochkin La -190 (Russian Лавочкин Ла -190 ) was a Soviet supersonic interceptor. It came to the beginning of the 1950s as a parallel design to MiG- 19th It existed only as a prototype, but instead went to her competition pattern in serial production.
Development
After the La -176 was the first Soviet aircraft reaches supersonic speed, Semyon Lavochkin developed the pattern from the beginning of 1949 to the La -190 on. The fuselage was lengthened by about five meters. The wings were given a 45 ° elevated to 55 ° leading edge sweep, but possessed in contrast to the La -176 does not have a boundary layer fences. The tail had a delta shape similar to that of a short time later built Yak -1000. The chassis was carried out in tandem design, that is, the hull was located the bug and a frosted double main gear and the wing ends a wheel. Other differences to its predecessor were the mid-wing on the fuselage the fuselage and the use of much stronger Ljulka AL -5 engine.
As of February 1951, the flight test. Stability problems in high speed range as well as poorer performance compared to the MiG -19 their sheer setting of the program and Lavochkin turned his last fighter project, the heavy interceptor La -250, too.
