CEF Designs Doors for Auxiliary Power Units (APUs) in Aircraft

APU in aircraftDid you know that CEF Industries, LLC designed the doors for auxiliary power units (APUs) on many aircraft in operation today? An APU is a small jet engine housed in the tail of an aircraft used to provide a source of electricity to power the aircraft when engines are switched off. APUs are also used if there’s an emergency that’s faulting the main engine or power sources.

An APU is needed when an engine-related emergency happens while an aircraft is in flight. If this happens, an APU will start mid-flight. APUs play a critical role in aircraft safety and operations. CEF contributes towards these safety measures by designing the door on the housing that encloses each APU engine. The door plays a critical role in the APU’s operation, because, in simple terms, if the door doesn’t open, the APU won’t run.

The APU doors that CEF designed can be found on the APUs on many regional jets, business jets, military aircraft and commercial aircraft. Some include the Canada Regional Jet 700 (CRJ-700), Bombardier Global 5000 business jets, Lockheed-Martin C-130 and Boeing C-17 military aircraft, Embraer 170-series and 190-series regional jets, and other aircraft, as well.

At CEF, we always work behind-the-scenes to ensure aircraft safety. In fact, we’ve been designing and manufacturing mechanical and electro-mechanical products and systems for our aerospace/aviation customers for 70 years now.
