Development and design

In 1955, the Czechoslovakian aero-engine company Motorlet commenced design of a new turbojet engine to power the Jet trainer being designed by Aero for a competition to equip all Warsaw Pact air forces, the Aero L-29. The resulting design, designated Motorlet M-701 was a single shaft centrifugal turbojet and was the first jet engine designed in Czechoslovakia (although Motorlet had previously built the Klimov VK-1 under license).[1]

The engine was first run in 1958, and powered the second prototype L-29 when it flew in 1960 (the first prototype had flown the previous year powered by a Rolls-Royce Viper). 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, about 9,020 had been built.[1]
