TR-1
Type	Turbojet
National origin	Soviet Union
Manufacturer	Lyulka
First run	9 August 1946
Major applications	Ilyushin Il-22 Sukhoi Su-10 Sukhoi Su-11 Alekseyev I-21

The Lyulka TR-1 was a turbojet designed by Arkhip Lyulka and produced by his Lyulka design bureau. It was the first indigenous Soviet jet engine.

Development

In May 1944 Lyulka was ordered to begin development of a turbojet with a thrust of 12.3 kN (2,800 lbf). He demonstrated an eight-stage axial-flow engine in March 1945 called the S-18. In early 1946 the Council of Ministers ordered that the S-18 be developed into an operational engine with a thrust of 15.5 kN (3,500 lbf). The TR-1 was developed in early 1946 and had its first static run on 9 August. It was tested in the air on a pylon fitted to a Lend-Lease B-25 Mitchell piston-engined bomber.^[1]

The TR-1 was not a success, proving to have less thrust and a higher specific fuel consumption than designed. Its failure led directly to the cancellation of the first Soviet jet bomber, the Ilyushin Il-22.^[2] Lyulka further developed the engine into the TR-1A of 20.5 kN of thrust, but its specific fuel consumption was very high and it too was cancelled.^[1]
