The role of fans of aerospace class

Aerospace class fans perform two main functions on airplanes: provide emergency diet and additional cooling.

Provide emergency nutrition
Pressure air turbines (RAT) in air -space class fans are an important system of backup power supply in extreme situations. Rat is triggered when an engine or auxiliary power system fails at the aircraft. He uses the power of the plunger, which occurs during the flight of the aircraft, to bring the turbine in rotation, thereby ensuring emergency nutrition of the cab and flight control system, guaranteeing that the aircraft can still perform basic operations when it loses power and helping the aircraft safely land.

Auxiliary cooling
In addition, aerospace class fans are used for additional cooling of aircraft. For example, in Airbus A320, fans are installed in the middle of the wheels for cooling. These fans will generate high temperatures up to 3000 degrees when landing aircraft. Installation of cooling fans allows you to exclude brake wear and avoid overheating of the niches of the chassis wheels, ensuring the safety of the aircraft in various flight conditions.
