123

The GTDE is a turboshaft engine with a free turbine, has a modular design, with the turbocompressor module being one-shaft with centrifugal compressor and one-stage turbine. The reduction gear of the power turbine is executed according to the two-stage multi-flow scheme. The purpose is to provide the independent pre-flight aircraft preparation without starting the main engines and their subsequent startup.

The gas turbine engine-power unit differs by a relatively small mass at high available power, is produced in several modifications for a number of domestic and foreign planes. The main modifications – GTDE-117 and GTDE-117-1 are installed on MiG-29, MiG-29К, Su-27, Su-30, Su-33, Su-35, etc..
