Product overview
The Jinpengda LF150 Thunder turbojet engine provides propulsion for small and medium UAVs, civil light aircraft and gliders. It delivers a maximum thrust of 150 kg with a thrust-to-weight ratio of 7.5. Its flight envelope covers speeds of 0–0.95 Ma and altitudes of 0–15000 m above sea level. The engine uses RP-3 or JET A fuel, with specific fuel consumption of 0.12 Kg/(N·h), and has a rotational speed of 55000 r/min.
The LF150 combines a single-stage centrifugal compressor, a reverse-flow annular combustion chamber and a single-stage axial-flow turbine with a fixed convergent exhaust nozzle. Its annular intake incorporates internal supports, a one-piece cast casing, four support struts and a flow-straightening cone. Equipment includes electronic control, a compressor-front starter-generator, one igniter plug and independent recirculating oil lubrication. Generator output is 2000 W at 28 V. The engine measures 707 mm long and φ272 mm in maximum outside diameter, with a dry weight of 20 Kg. Starting covers 0–6000 m and 0–0.6 Ma; the first overhaul interval is 50 h or 200 starts.
