PBS-TJ-100
 
Development of the TJ 100 turbo-jet engine began in 2002, as a drive unit for MAE UAV and piloted flying vehicles.
The TJ 100 is single-shaft engine with single-stage radial compressor, annular combustion chamber, single-stage axial turbine, and stationary exhaust jet.
In the compressor intake there is a brushless starter generator, which enables the starting from the board network and power generating in course of the engine operation.
The intake air is compressed in the radial compressor wheel, proceeds through radial and axial diffuser into the combustion chamber, where it is mixed with fuel sprayed by several fuel nozzles. Combustion gases arising in fuel burning in the combustion chamber expand through the single-stage axial turbine and exhaust jet into the atmosphere.
The rotor of the engine is mounted on 2 ball bearings lubricated with pressure oil.
Several versions were produced, varying by length of output nozzle, mounting, and by power.
PBS produce TJ 100, TJ 100C, TJ100E, and TJ 100I of 100 daN (225 lbf) power. The TJ 100A and TJ 100S are produced with 110 daN (247 lbf) power.
