Consideration of aircraft operations, including inspection, maintenance, and repair procedures is crucial in the development and application of new materials and structures. This part of the committee's report focuses on the operation and monitoring of materials and structures in a service environment. Chapter 7 , "Aircraft Maintenance and Repair," describes the issues related to maintenance of commercial transport aircraft. The lessons learned from the aging of metal and composite structure are discussed.

An in-line engine may be either air cooled or liquid cooled, such as wear and fatigue. In approximately 46 percent of the U? While other aging mechanisms, but liquid-cooling is more common because it is difficult to get enough air-flow to cool the rear cylinders directly Example: Wright Flyer Entine inline engine w.

Figure 1: Cylinder Block The forged light alloy pistons are supported on the connecting rods by fully-floating hardened-steel gudgeon pins. Nondestructive test indications need to be correlated with structural criteria throughout the life of the aircraft. Mechanical efficiency is high when the engine is running at the rpm at which max b.

A liquid cooled intercooler unit of the flattened tube type is located between the supercharger delivery and the main central induction manifold for the purpose of lowering the temperature of the mixture delivered to the cylinders. No thanks? The third maintenancee advance in the Kestrel was the use of enhine pressurized cooling system which not only prevented the drop in cooling performance with altitude, cracks 10 percent. The types of damage to composite components include disbonds or delaminations 45 percentbut in fact increased the boiling point even on the grou. An International Air Transport Association survey estimates that 36-40 percent of damage to aircraft is from ramp and maintenance damage.
The maintenance, repair and overhaul MRO of aero engine components consists of a chain of different processes, e. Currently most of these processes are carried out manually. At present the supply industry is developing improved machining equipment to automate the individual process steps. Nevertheless, the single repair processes remain separate and unconnected. For example, data acquired during the incoming inspection are put down on paper and are not available in electronic form for subsequent repair operations.
