Journal of Aircraft, 1972
Propulsion requirements for the next generation of civil aircraft are examined and some new and quite demanding needs are defined—larger engine sizes, higher takeoff thrusts, and much lower noise levels. The remarkable propulsion advances over the past two decades are charted and, from these, projections are made for the next round of improvements. All

The future of aircraft propulsion
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2000The 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.

Jet propulsion for quiet aircraft
The Journal of the Acoustical Society of America, 1974A novel method of jet noise reduction has been subjected to bench and wind tunnel tests. This patented method uses very small nozzles arranged on struts protuding from the upper surface of an aircraft wing. Bench tests included various arrangements of nozzles on each strut; tests with heated air; tests of noise power and directivity versus number of ...

Hydrogen for aircraft power and propulsion
International Journal of Hydrogen Energy, 2020Abstract Due to the fact that any type of aerospace vessel needs energy, and in the future, this energy must be nuclear and obtained by fusion, not by fission, this paper presents shortly a method by which nuclear fusion can be more easily achieved on an industrial scale.

Hybrid-Electric Propulsion for Aircraft
Journal of Aircraft, 2015Against a background of increasing energy demand and rising fuel prices, hybrid-electric propulsion systems have the potential to significantly reduce fuel consumption in the aviation industry, particularly in the lighter sectors. By taking advantage of both electric motor and internal combustion engine, hybrid-electric propulsion systems provide not ...

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 ...
