Abstract：Turboshaft engines are smaller, lighter and have shorter shafts than large turbofan and turbojet engines. Due to their good high altitude performance and wide power range, turboshaft engines have gradually replaced piston engines in unmanned helicopters. However, piston engines are less expensive, so they still have the absolute advantage in small unmanned helicopters. Further research is needed to develop economical low power turboshaft engines. This study analyzed the design of a 300 kW turboshaft engine using Gas Turb, a thermodynamic turbine analysis software, with the blade modeling module of ANSYS used to design the impeller and blades of the centrifugal compressor. Three-dimensional simulations of the centrifugal compressor verify the feasibility of this design.
