TJ80 Turbojet Engine

TJ80 is a small turbojet engine that has been designed for missiles, target drones and UAVs.
Main features:
• Compact design
• Excellent weight/thrust ratio
• Low fuel consumption in the given output category
• Uniform fuel for both the engine and lubrication
• Maintenance-free operation
• Electric start, possibility of in-flight restart
• Integral generator and inverter
• Startability at high altitude and at high speed

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.
