Modern military aircraft engines

Błaszczyk J., Chachurski R., Kozakiewicz A., Zalewski P.

Research Bulletin / Warsaw University of Technology, Institute of Aeronautics and Applied Mechanics

2000

nr 10

49-56

Propulsion systems of modem multirole aircraft are presented in the paper focusing on concept, requirements, state of the art. The requirements, imposed by the multi-role aircraft concept on their power plant are presented and discussed. This paper also highlights the problem of number of engines, survivability, etc. The turbofan engines of primary multirole aircraft both in service and at the development stage were compared and evaluated as well. Their essential parameters which have a direct impact on the aircraft performance: such as, specific thrust, thrust to weight ratio, specific fuel consumption, bypass ratio, mass and other were assessed. The comparison both contemporary engines and their parameters can reveal the development trends in military engine technology.

Analysis of the technical parameters and performance of modern military multi-role aircraft

Błaszczyk J., Olejnik A., Zalewski P.

Research Bulletin / Warsaw University of Technology, Institute of Aeronautics and Applied Mechanics

The paper presents an analysis of changes in technical parameters and flight performance of fighters flown after 1960. Analysed also some selected technical indexes and relative parameters, which decide about their functional qualities. As the result of the analyses made. the trends in development of this class of aircraft have been considered.
