Trends in Military Aircraft Propulsion

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 1989
The major factors determining the choice of engine cycle for a combat aircraft are the requirements of the design mission and those of aircraft speed and agility. The requirement for jet-borne flight in short take-off vertical landing (STOVL) aircraft imposes further demands on cycle and configuration.

Hypersonic flight [scramjet aircraft propulsion]

IEEE Spectrum, 2004
Current turbojet engines cannot propel an aircraft to hypersonic speeds -their spinning shafts and compressors would simply collapse. To solve this problem, groups in the United States, Japan, Australia, and other countries are working on a propulsion system that burns fuel combined with air flowing at supersonic speeds through the engine, which is ...

The future of aircraft propulsion

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2000
The next century offers many challenges to the aero-engine industry in both the civil and the military markets. The primary driver in both markets will be to reduce the cost of acquiring, operating and supporting the product throughout its life. Reducing the environmental impact will be an additional challenge for the civil sector.

Cycloidal Propulsion Applied to Aircraft

Transactions of the American Society of Mechanical Engineers, 1928
Abstract After reporting observations on the flight of gulls which indicated that the wing top moves with a cycloidal motion, the author proceeds to an analysis of this type of motion as it might be applied to the propulsion of aircraft.

ATOMIC POWER And Aircraft Propulsion

SAE Technical Paper Series, 1949
<div class="htmlview paragraph"><b>A</b>FTER outlining the fundamental physical background for the release of atomic energy, the author shows that the high concentration of energy and the high cost and relative scarcity of atomic fuels mark them for use where there is a high premium on performance, rather than on direct cost per unit ...

Scar tissue and aircraft propulsion development

The Aeronautical Journal, 1972
Involvement with the development of an aircraft engine can create deep mental scars. There seems to be an almost infinite variety of ways to encourage failure when considered in detail, and at the same time, there is no rule that will ensure success, except “Don't make any mistakes!”, a rather absurd bit of guidance.
