WP-20-23

Full specification

The WP-20-23 is a one-touch electronic-start turbojet for small fixed-wing airframes. Rated thrust is 20–23 kgf at sea level, with a 46,000–108,000 rpm speed band, acceleration under 8 s and a 4,000 m start ceiling. The kit arrives as a complete installation: engine body, ECU control box with fuel pump, ground support unit, throttle and start-stop cabling, engine power cord, spare parts, fuel filter and four fuel hoses. Fuel is aviation kerosene with 3–5% lubricant, and the rated exhaust temperature is 850 °C. Thrust varies with ambient temperature; the design point is sea level, Mach 0, 15 °C and 101,325 Pa.

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.
