Air Turbine Driven Engine Starter-Generator

An Air Turbine Driven Engine Starter-Generator is a device used in aircraft to start the engines and provide electrical power. It combines the functions of a starter, which is used to initiate the engine's rotation, and a generator, which produces electrical power for the aircraft's systems.

The Air Turbine Driven Engine Starter-Generator operates by using compressed air from the aircraft's pneumatic system to drive a turbine. This turbine is connected to a gearbox, which in turn drives the engine's crankshaft to start the engine. Once the engine is running, the turbine continues to spin and generates electrical power to supply the aircraft's electrical systems.

This type of starter-generator is commonly used in aircraft because it provides a reliable and efficient means of starting the engines and generating electrical power. It eliminates the need for a separate starter motor and generator, reducing weight and complexity in the aircraft's design.

Air Turbine Driven Engine Starter-Generators are typically found in larger aircraft, such as commercial airliners and military transport planes. They are designed to withstand the high demands of starting large jet engines and providing continuous electrical power during flight.

Overall, the Air Turbine Driven Engine Starter-Generator is an essential component in aircraft, ensuring reliable engine starting and electrical power generation for safe and efficient operation.
