Types and design features of aerospace fans

Types and design features of aerospace class fans include:

Air turbine with air pressure (RAT): This fan is usually installed in the lower part of the aircraft and is used to provide emergency electric and hydraulic support in case of engine failure . RAT system consists of2-4 of medium length blades, which can rotate in high -speed air flow, providing the aircraft with the necessary electric and hydraulic hydraulic energy .

Turbopropic (turbopropic) engine: the turboprop engine sets the front screw through the turbine, creating a pushing (traction) force . This design is more common in regional aircraft, since it is more economical .}}}}}}}}
