Product overview
The Swiwin SW300B is a turbojet engine for aircraft propulsion, rated at 30kg thrust. It measures 132mm in diameter and 331.4mm in length and weighs 2560g. Its associated equipment comprises power, throttle and signal cables, a display, an SWP50D fuel pump, an ECU(V3), a fuel filter and a ball valve. The propulsion architecture incorporates an in-house-developed brushless starter motor and electronic engine control, with a single bus carrying data signals between the engine and control system.
The four-port fuel pump uses dual inlets and dual outlets, with 6 mm inlet and 4 mm outlet connections, to break up bubbles that could cause flameout. The ECU provides constant-speed control and flameout restart capability; the restart setting is off. The engine uses aviation kerosene with 3%～5% lubricating oil. Fuel consumption is ≤820g/min, rated exhaust temperature is 750℃, and the maintenance interval is 25H. Its rotational speed range is 38000～98000, with an idle speed of 38000.
