doi:10.7523/j.issn.2095-6134.2011.3.003

Abstract

Abstract:

By using CFD technology, the flow field of a blockerless thrust reverser experiment model with the bypass ratio of 9 was simulated. Variations in reverser efficiency, cascade flow ratio, and the injection flow ratio with the injection parameter was described. Based on detailed analysis of the thrust reverser flow characteristics, we found that the location of secondary injection, slot angle, and slot width have great impacts on the performance of thrust reversers. The optimum value of injection parameter can then be obtained.

Key words: blockerless thrust reverser, numerical simulation, secondary flow injection, turbofan engine
