Aircraft-Engine-Accessory Vibration
Transactions of the American Institute of Electrical Engineers, 19441. The overhang-moment limit, or still better a limit on the moment of inertia of the accessory about a line through the center of the accessory mounting surface, would be helpful by limiting one of the two factors which control the natural frequency of the accessory-rear-cover combination.

Aircraft Engineering and Aerospace Technology, 1930
THE subject of aircraft engine installation has not received as much attention during the past as it should have done, particularly from an engineering and service standpoint. Many of the failures of power plants in the air have not been caused by engine failure, but by engine installation.

Enhancing Aircraft Engine Condition Monitoring
IFAC Proceedings Volumes, 1994Abstract Engine Condition Monitoring (ECM) plays an important role in the day-to-day business of modern airlines. It ensures efficient on-condition maintenance, contributes to increased safety and improved (dispatch) punctuality, while yielding important operational cost savings.

Heat recovery from aircraft engines
Collection of Technical Papers. 35th Intersociety Energy Conversion Engineering Conference and Exhibit (IECEC) (Cat. No.00CH37022), 2000The paper deals with the problem of heat recovery from aircraft engines, with specific reference to jet engines and turbo propeller engines. In actual propulsion systems, the trend for cycle maximum temperatures is for very high values, with a consequent increasing of discharge temperature, due account also given to operative modalities of the ...

Aircraft engine acoustic liner
The Journal of the Acoustical Society of America, 1999A middle layer (22) having partitioned cavities (28) is sandwiched between an imperforate sheet (24) and an optional perforate sheet (26) to form a low resistance acoustic liner (22). A preferred method of manufacture of the low resistance acoustic liner (20) uses aspects of the buried septum technique including placing an uncured imperforate septum ...

Titanium and Aircraft Engineering
Aircraft Engineering and Aerospace Technology, 1959TITANIUM, with a melting point of 1,660 deg. C, higher than that of nickel or iron, a density little more than one‐half that of steel, and a corrosion resistance in certain environments superior to stainless steel, is evidently a metal of significance to aeronautics.

Alloy design for aircraft engines
Nature Materials, 2016Metallic materials are fundamental to advanced aircraft engines. While perceived as mature, emerging computational, experimental and processing innovations are expanding the scope for discovery and implementation of new metallic materials for future generations of advanced propulsion systems.

CORROSION 1977, 1977
Aircraft engine cleaning, either by treatment of individual components after disassembly, or field cleaning of entire engines, is designed to accomplish several things. Dirt, oil mist, salt and other atmospheric contaminants are deposited on engine parts such as compressor blades during operation as well as when the engine is shut down.
