Turbojet engine BPS TJ100

The BPS-TJ100 turbojet engine is a small turbojet engine capable of rapid start (within 5 seconds), resistant to low temperatures and severe cold (-50°C), capable of high-altitude start (6000m), and stable operation at altitudes greater than 8000m.

The engine mainly consists of a 1-stage high-pressure ratio centrifugal compressor, an annular vaporizer tube combustion chamber, a 1-stage axial flow turbine, casings, and a fuel control system. The engine adopts a unique high thrust-to-weight ratio compressor design and, through an embedded generator mounting structure, achieves 1200W power extraction from the engine itself.

Simultaneously, the application of a 0-2-0 bearing support structure combined with direct fuel lubrication effectively shortens the shaft span, simplifies the lubrication system, increases the thrust-to-weight ratio. The engine overall has a simple structure and compact layout.
