The PBS TS100 is a small turboshaft engine produced by a Czech turbine engine manufacturer PBS Velká Bíteš. The engine with a maximum power of 241 hp (180 kW) has been developed for light helicopters weighing up to 2,204 lb (1,000 kg).[1]

PBS TS100
Type	Jet aircraft engine
National origin	Czech Republic
Manufacturer	PBS Velká Bíteš
Major applications	Curti Zefhir

In 2022, the PBS TS100 engine was acquired by the Korean Aerospace Research Institute (KARI) to develop new hybrid propulsion system.[2][3]

Design

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.[4]

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 6,560 ft (2,000 m).

Two versions of the PBS TS100 engine are available based on the number of rpm:

• PBS TS100 ZA with 5,978 RPM
• PBS TS100DA with 2,158 RPM

Applications

• Curti Zefhir[5]
