【Abstract】 A flame holder for aircraft afterbuner proposed for t h e first time is a V-shape bluff body with a slit. Two types of the bluff body w ere investigated in an open wind tunnel to get their drag force features and the ir wake structure at different slit width. By comparing the results, it is prov ed that the “streamlined” flame holder has a better drag feature than the “no n-streamlined” flame holder, but its reverse flow zone is smaller.更多还原
