Abstract

Experiments and numerical calculations were conducted on the flow field of a model ejector ramjet configuration to investigate fundamental fluid dynamic aspects of its pumping and mixing effects. Also a one-dimensional flight performance analysis program was constructed with a simple ejector modeling. After comparing the model with some of the previous experimental and numerical results, a flight performance analysis was conducted with the program. The present states of the program and some features to be improved are presented.
