| Abstract: | Key technology in the design of combustion efficiency sampling-probe of scramjet engine was analyzed. A water-cooling sampling-rake with sixteen-point sampling- probe was designed and made. Flow character, chemical reaction frozen in the probe and the availability of the system was analyzed. This sampling analysis system can be used to test the combustion efficiency of scramjet engine. |
