A turboshaft engine is a type of gas turbine engine designed to produce shaft power rather than thrust. It works by burning fuel to create hot gases that spin a turbine. This turbine is connected to a shaft, which can drive various types of machinery, such as helicopters or generators. Turboshaft engines are commonly used in aircraft like helicopters and in industrial applications. 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.
