Product overview
The HJ150 is a propulsion engine for integration into medium and large UAVs and other aircraft platforms. Its physical architecture pairs a single-stage centrifugal compressor with an axial turbine. The engine integrates a fuel pump, solenoid valve and temperature sensor, and supports electric and pyrotechnic starting. External electrical generation provides 2000 W for other aircraft equipment, giving the engine an electrical supply role alongside its thrust output. Its maximum thrust is 155 daN.
For installation planning, the engine measures 250 mm in diameter and 735 mm in length, with a weight of 24 kg. Maximum rotational speed is 56200 rpm; at maximum speed, fuel consumption is 4.20 L/min and specific fuel consumption is 1.30 kg/daN·h. Operating limits include a 4000 m maximum starting altitude, 12000 m maximum flight altitude and 0.9 Ma maximum flight speed. The operating temperature range is -40 to 55 °C, with maintenance scheduled every 25 hours.
