Air Starter Market Share, Size, Growth & Trends Forecast Analysis 2018 to 2025
Air starters can be for vane motors or turbine motors. Vane air starters work on the principle of positive displacement, while turbine air starters consist of a radial inward flow or axial flow turbine. The compressed air for air starters can be provided by bleed air from a running engine, auxiliary power unit (APU), or a portable gas generator. When a limited volume of starting air is required for a short crank cycle, vane starters are used. On the other hand, when large amount of starting air is available for a longer crank cycle, turbine starters are used. Air starters in general have larger operational life compared to electric starters. They have higher reliability, lighter weight, and are easier to build. Due to their simple and modular design, turbine air starters are preferred for large turbofan engines used in aircrafts.
