Where is bleed air from a turbine engine taken from

Valves are incorporated into the system to provide the means to automatically or manually isolate parts of the bleed air manifold or individual components in the event of a failure. Some of these defenses include:. The electronic and mechanical defenses, as listed above, are essential to the timely detection and successful containment of a bleed air leak. However, many emergency or abnormal checklists for bleed air faults require some post action analysis to assess whether the action taken has been successful.

A critical part of that analysis is a sound understanding, by the pilots, of the pneumatic system and all of its associated functions and components. If the isolation has not been successful, diversion should be initiated and an appropriate balance struck between the time spent on analysis and the need to get the aircraft on the ground as quickly as possible. This prevents ice from accumulating, breaking loose, and being ingested by the engine, possibly damaging it.

MSM aerospace fabricators has developed a niche, specialist expertise in forming hydroforming , welding, laser cutting, laser welding and general fabrication of these often complex components and assemblies….. If you need more information or you would like us to get in touch to discuss a specific requirement please contact a member of the MSM team.

Our 80 year heritage in aircraft component manufacture allows us to specialise in complex forming and welding of high temperature metals. Carbon graphite is a popular choice for engineers in many similar industrial applications for its ability to lubricate rubbing components.

Without a proper bleed air distribution system, the potential energy that can be derived from bleed air is essentially lost. Considering all the systems within an aircraft that need to be powered, conserving any and all energy possible is of utmost importance to engine efficiency and optimal performance. Directing the flow of extremely hot, pressurized air is no easy task, and can't be handled by just any material. Bleed air valves must be able to operate at high altitudes, withstand extreme temperatures, and be as lightweight as possible.

With a variety of strict considerations and regulations in mind, engineers are tasked with a critical materials selection. Engineers look for materials like mechanical carbon graphite that have uniquely beneficial material properties:. One property of carbon graphite that is often overlooked yet is critical in aerospace applications is its weight.

Check the functionality of your engine bleed air valves. Be aware that the bleed valve can become stuck in a particular position, in which case, the following should be noted:. Above all else, always reference the OEM Maintenance Manuals for engine troubleshooting and repair, since engine and aircraft make and models vary with the operation. Related Articles.
