Abstract:

The importance of the research experiment of discrete fuel injection in aeroengine combustion chamber is briefly discussed. The experiment shows that it is able to maintain good atomizing quality at different flight conditions and increase combustion efficiency by changing fuel supply frequency. At the sametime, the problems about the discrete fuel injection test on the combustion chamber test bed, for example; the choice of nozzles, the discrete injection quality test and the test installations are discussed. Some significant conclusions are obtained.

Key words: aviation engines, combustion, test
