Turbojet engine TJ 100

Engine description

This small turbojet engine has been developed for light air vehicles, such as light and ultralight sports planes, sailplanes equipped with auxiliary engine, piloted vehicles of EXPERIMENTAL class and various unmanned air vehicles. TJ 100 is currently sold in several variants. Since 2008 about 200 units of TJ 100 have been delivered (state at December 2010). TJ 100 is completely newly developed driving unit with excellent weight/thrust ratio. In the development of TJ 100 latest know-how and technologies were used from the field of turbine engines. In the category of small turbojet engines TJ 100 with thrust up to 1200 N ranks among the best in the world.

Technology of the engine

Single-stage radial compressor, radial and axial diffuser, annular combustion chamber, and single-stage axial turbine. Rotor bearings are lubricated by autonomous oil system. The engine is controlled by an electronic system. Start of the engine as well as of the fuel and oil pump is electrical. Power supply is ensured by integral generator and DC-DC converter. Ignition system is a low-voltage system.

Engine variants

Variants are created on the basis of specific customers requirements; as a rule they have the following differences:

  • installation – the basis are 3 fixing points, which, depending on application, can be extended by a stainless frame
  • air intake section – depending on aircraft type, various types of air intake sections; the engine can be equipped with its own cover or by intake section cover delivered by the customer
  • exhaust nozzle – standard nozzle can be modified or extended
