Aerospace Components: Air Management System
(Bleed Air and De-icing) Solution
Handling Comfort and Safety
An aircraft’s air management system is comprised of all systems that are powered with bleed air (highly pressurized hot air coming from the engine). The first area you see when looking from the engine is the bleed air system, made up of different types of valves that transfer bleed air from the high-pressure compressor section of the engine into pressure regulating valves, high pressure valves, over-pressure valves, fan air valve actuators and cross bleed valves.
The bleed air system transfers bleed air into the anti-ice system, which is an important safety feature. When flying at high altitudes in subzero temperatures, ice forms on the wing of aircraft and a deicing protection system destabilizes the ice using hot air coming from the engine, thus allowing the slipstream to dislodge it and remove it from the wing. Our OmniGasket™ part is mounted at the interface between the telescopic duct and the wing leading edge and protects the aircraft’s wings.
Bleed air is important for comfort as it goes into the air conditioning system by turbo-compressors.
What all these systems have in common is the need for reliable sealing control, wear and friction control and tolerance control. OmniSeal®, Rulon® and Meldin®7000 parts are used for their excellent temperature range, low coefficient of thermal expansion (a good option comparable to aluminum that is often used in these applications), low friction and wear resistance.
