Product overview
The Sinohawk Power HJ50 is a compact turbojet propulsion unit for small and medium-sized UAVs and high-speed aircraft. Its physical architecture combines a single-stage centrifugal compressor with an axial-flow turbine, while an electric motor provides starting and the control system is integrated into the engine body. At 177 mm in diameter, 460 mm long and 5.5 kg, the engine provides concrete dimensions and mass for propulsion installation planning. Its compact construction supports integration, and its modular design facilitates routine maintenance and servicing.
The HJ50 has a maximum thrust of 58 daN and a maximum rotational speed of 83000 rpm, with airflow of 1.05 kg/s and an exhaust temperature of 750 °C. At maximum rotational speed, fuel consumption is 1.81 L/min and specific fuel consumption is 1.50 kg/daN·h. Its operating limits distinguish a maximum starting altitude of 4000 m from a maximum flight altitude of 12000 m. Maximum flight speed is Mach 0.9, the operating temperature range is -40 to 55 °C, and the maintenance interval is 25 hours.
