| 摘 要： | 本文介绍了在北京空气动力研究所炮风洞 M 数为6、7、8的气流中进行具有高温喷流的模型底部热流和压力测量试验的有关试验技术。试验结果表明底部对流热流和压力测量值随外流 M 数增大而减小,他们都大于无外流时的测值。辐射热流不受外流影响。

| Abstract: | This paper presents the tests of base heat transfer andpressure measurements on a cone-cylinder model with high temperaturejet.They were carried out at the gun tunriel in BIA.The air was usedas test flow with Mach numlers being 6,7,8 respectively,total pressureof 5.9MPa and total temperature of ll00K.The high termperature jetwas similar to a solid rocket exhaust.Experimental apparatus andmethod of tests are descriled briefly and its results are as follow:(1) The base convective heat transfer and pressure varies inverselywith Mach number of the tunnel flow and were higher than the measuredvalues without tunnel flow.(2)The tunnel flow has no effect on the base radiative heat transfer. |
