A turboshaft engine is a type of gas turbine engine designed primarily to produce shaft power rather than thrust. It operates by compressing air, mixing it with fuel, and igniting the mixture to create high-speed exhaust gases. These gases then drive a turbine connected to a shaft, which can be used to power helicopters, ships, and industrial machinery. Turboshaft engines are commonly found in helicopters like the Bell 206 and Eurocopter AS350. They are efficient and lightweight, making them ideal for applications where power-to-weight ratio is crucial. Their design allows for smooth operation and quick response to power demands.
