| Abstract: | A unique supersonic wind tunnel facility using resistance heaters has been built to simulate the operation of a scramjet over a range of Mach numbers of 3.0 to 4.5.A number of preliminary experiments results from calibration of both the facility and the various components were introduced.Based on the previous experience and the experimental results published worldwide,a new combustor configuration using cavity flame holder to create recirculation and promote the fuel/air mixing has been developed.And the co... |
