# Lyulka TR-3

The Lyulka TR-3 was a Soviet axial turbojet designed after World War II by Arkhip Mikhailovich Lyulka.

## Development

The Lyulka TR-3 was a single-shaft turbojet with a seven-stage axial compressor. It had an annular combustion chamber with 24 nozzles and a single-stage turbine. It had a fixed exhaust nozzle and had a pneumatic SV-3 starting unit, although this was later replaced by a turbine unit. It had a thrust of 46 kN (10,000 lbf). It was used in the Ilyushin Il-30 during 1949, but was superseded by later versions. The improved TR-3A version was redesignated as the AL-5 to honor Lyulka in 1950.
