Development and design
In 1955, the Czechoslovakian aero-engine company Motorlet commenced design of a new turbojet engine to power the Aero L-29, a jet trainer being designed by Aero for a competition to equip all Warsaw Pact air forces. The resulting design, designated Motorlet M-701 was a single shaft centrifugal compressor turbojet and was the first jet engine designed in Czechoslovakia (although Motorlet had previously built the Klimov VK-1 under license).
The M-701 was first run in 1958, and engine no.4 was tested on an Avia B-228 flying laboratory in December 1959. Engine no.8 powered the third prototype L-29 when it flew on 12 July 1960 (the first two prototypes had flown the previous year powered by Rolls-Royce Viper engines). The L-29 was selected as the winner of the competition, and was ordered in large numbers, with the M-701 entering production at Jinonice near Prague in 1961. By the time production ended in 1989, more than 9,250 had been built.
