The PBS TS100 turboshaft engine is equipped with an autonomous oil and fuel system, brushless electric starter generator and a digital ECU. The ECU controls the acceleration and deceleration of the gas generator to maintain a constant output shaft speed. The ECU also provides subsequent automatic cooling of hot components after the engine stops. The turboshaft engine can be controlled by an analogue or digital interface. The maximum continuous power mode of 214 hp (160 kW) is available up to . Variants
Two versions of the PBS TS100 engine are available based on the number of rpm:
