EDePro | TSE-200
Turboshaft Power – From Design to Testing and Certification


Used in applications that require a sustained high-power output, high reliability, small size, and low mass, the TSE-200 is representative of EDePro’s gas turbines family for light helicopters, UAVs, and auxiliary power units.

The maximum continuous power mode is 150 kW and the operating altitude is up to 7,000 m, both at low and high temperatures. It can be started at temperatures between -40°C and +50°C without preheating. The engine’s configuration is based on a back-to-back radial compressor and turbine gas generator along with a single-stage axial power turbine connected to the gearbox. The main technologies used are investment casting, laser welding, and CNC machining. Due to the unique combustion chamber design, it can run at almost all known fuels.

Digitally controlled with online condition monitoring, TSE-200 is equipped with an electric generator and a digital engine control unit (ECU), which controls the acceleration and deceleration, and provides cooling of the engine nozzle and turbine during the auto-stop procedure.  The Controller Area Network (CAN bus) is used for maintaining the communication between the engine control unit and other devices, as well as other purposes, such as data collection, machine state monitoring, real-time diagnostics, and many more.  

End-to-end design and production of TSE-200 are followed by engine testing at our turboshaft test stands and jet propulsion laboratories – where air-breathing engines and their components are assessed.
