The Lavochkin La-9 ( Russian Лавочкин Ла-9 , NATO reporting name Fritz ) was one of the last with piston engine powered fighter aircraft of the Soviet Union .
history
The La-9 was developed as a further development of the La-7 , taking into account the experience gained from the front. It was built with extensive use of duralumin and received new wings with a shorter span and an enlarged rudder . A 1,870 PS (1,375 kW) radial engine Schwezow ASch-82 FNW served as the drive . The cockpit has been completely redesigned. The La-9 was armed with four 20 mm SchWAK cannons arranged on the nose of the fuselage . On the La-9bis, they were replaced by four 23-mm NS-23 cannons .
The first flight of the La-130 prototype took place in early 1944. The La-9s were still in service with the Soviet air forces a few years after the end of the war , until they quickly became obsolete and decommissioned due to the rapid development of jet fighters. In August 1948, a small series of two-seat school hunters La-9UTI was produced.
The Chinese Air Force PLAAF also used the La-9 in the Korean War . More La-9s went to the Romanian and Hungarian Air Forces .
Five La-9s were delivered to the Aviation Technical School in Kamenz ( Volkspolizei - Dienststelle 500) for training purposes in 1952 to train personnel for the VP-Luft, but only for ground training.
Analogous to the La-7S (La-126PRWD), tests with Bondarjuk-PRWD-430 ramjet engines under the wings were carried out from the end of 1946 with a machine called the La-138 . This allowed the top speed to be increased briefly by 107 to 112 km / h. Experiments with pulse thrust tubes RD-13 (as La-9RD ) resulted in a speed increase of 127 km / h.
