240A

Full specification

The 240A is a 24 kgf turbojet for UAV and target drone airframes. Speed range is 38,000–116,000 rpm with a 750 °C rated exhaust temperature and a maximum fuel flow of 780 g/min on aviation kerosene with 3–5% lubricant. Starting is one-touch electronic from a 3S LiPo pack, and the service interval is 25 h. Maximum operating altitude is 10,000 m, maximum flight speed 1,100 km/h and maximum start altitude 4,500 m. The engine weighs 1,740 g; with the ECU V3, brushless fuel pump and cables the complete set is 2,160 g.

Rated values from the model datasheet; factory test performance can vary by 2–3%. Altitude, Mach and temperature limits are operating limits, not guarantees of airframe performance.

Fitment notes

1. 01Fuel is aviation kerosene with the lubricant ratio stated above. Fit a 20–50 µm filter before the pump and keep supply pressure inside the datasheet range.
2. 02Ground starts follow the ECU's automatic ignition sequence. Stay within the stated start altitude and temperature limits; a start that times out is aborted by the controller.
3. 03Keep the intake and exhaust clear during runs. The manuals specify 3 m in front and 5 m to each side as a safety distance for ground operation.
