Web23 linhas · The typical air turbine starter consists of an axial flow turbine that turns a drive coupling through a reduction gear train and a starter clutch mechanism. The air to operate an air turbine starter is supplied … Starting of a gas turbine engine requires rotation of the compressor to a speed that provides sufficient pressurised air to the combustion chambers. The starting system has to overcome inertia of the compressor and friction loads, the system remains in operation after combustion starts and is disengaged once the engine has reached self-idling speed.

WebIf an airplane has more than one engine, it can get the air from another engine. Some high-pressure air is often ducted from an engine for other uses. This is known as bleed air, and bleed air is often used to help start a turbine engine. But to use bleed air to start a jet engine, another jet engine needs to be already running.
