WP120

Full specification

The WP120 sits at the entry to the heavy class: 120 kgf at 62,500 rpm, 14.5 kg dry, 585 mm long. Specific fuel consumption is 1.25 kg/kgf/h at maximum state and 3.2 at idle, where thrust stays at 14 kgf or below. The TBO is 20 h, acceleration and deceleration are within 15 s each, and the start ceiling is 5,000 m with a 50 s ground start. The integrated ECU reports over RS-422 at 115,200 bps. Fuel is RP-3 with 5% lubricant at ambient pressure plus 30–50 kPa.

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.
