TJ400 Turbojet Engine

TJ400 turbojet engine is a highly reliable single-spool turbojet engine with a single-stage radial compressor and an axial flow turbine. Its simplicity and high thrust/weight ratio make it a suitable candidate for high-speed experimental aircraft and aerial target drones. The innovative FADEC-type ECU has a flexible communication interface and backup modes to increase flight safety.

Technology:

• Fuel metering unit: Provides stable thrust control and engine starting at high altitudes

• Brushless starter system

• Advanced igniter: Provides engine starting at high altitudes (above 20.000 ft)

• Starter/Generator option is on the way.
