Aircraft engine exhaust measurement

Air & Space Europe, 2001
Abstract Increasing consciousness of the potential impact upon the atmosphere of pollutant emissions from aircraft has focused attention upon the need for accurate measurement of such emissions. In this paper, the various constituents of aero engine exhaust which may be significant in their impact upon the atmosphere are identified and the current ...

Aircraft-Engine-Accessory Vibration

Transactions of the American Institute of Electrical Engineers, 1944
1. 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.

Optics in aircraft engines

Proceedings of the IEEE 1991 National Aerospace and Electronics Conference NAECON 1991, 2002
The authors describe optical IR&D (independent research and development) programs designed to demonstrate and evaluate optical technologies for incorporation into next-generation military and commercial aircraft engines. Using a comprehensive demonstration program to validate this technology in an on-engine environment, problems encountered can be ...

Magnesium and Aircraft Engineering

Aircraft Engineering and Aerospace Technology, 1960
MAGNESIUM, because of its low density, has obvious possibilities as an aircraft structural material. The useful magnesium alloys have densities in the range 1·76 to 1·83, compared with the aluminium alloys range of about 2·5 to 2·8. The melting point of magnesium is 650 deg. C., almost identical with that of aluminium (660 deg.

Aircraft Engine Maintenance and Digital Twin Technology in Aircraft Engines

Journal of Data Analytics and Engineering Decision Making
Aircraft engine maintenance stands as a critical aspect of aviation safety and operational efficiency. Traditional methods often rely on periodic inspections and scheduled maintenance routines, which may not fully capture the dynamic conditions and potential anomalies within the engine.

Lubrication of Aircraft Engines

Aircraft Engineering and Aerospace Technology, 1930
NO one interested in the question of lubrication can fail to appreciate the contribution of Messrs. Thornycroft and Barton to this subject. With the validity of most of the experiment and with the conclusions drawn from it, we can all agree, but a wider and more impartial view of the whole subject makes one hesitate to accept, at any rate in their ...

Space and the Aircraft Engineer

Aircraft Engineering and Aerospace Technology, 1987
EARTH is in space and it is no more extraordinary for man to use space to look down on Earth, as for centuries he has used Earth to scan the stars. Contrary to popular belief, man took to space and utilised it just as soon as he was given the means. When did the space age begin?
