Product overview
The Swiwin SW120B is a turbojet engine for aircraft propulsion integration. It delivers 12kg of thrust, measures 99mm in diameter and 241.4mm in length, and weighs 1280g. Associated components include power, throttle and signal cables, a display, an SWP30S fuel pump, ECU(V3), a fuel filter and a ball valve. These identify the fuel-delivery and electronic-control hardware associated with the engine, without establishing a complete supplied package. The dimensions describe the engine itself.
The engine uses aviation kerosene with a lubricating oil proportion of 3%–5%. Fuel consumption is ≤350g/min, rated exhaust temperature is 750℃ and the maintenance interval is 25H. Rotational speed spans 38000–125000, with idle at 38000. A single bus carries data between the engine and control system. The ECU provides constant-speed control and flameout restart capability, while the engine-start, engine-running and starter parameter table specifies flameout restart as off. That table also includes a ≥10V voltage setting and a 13V fuel pump limit.
