摘要
等动力学取样火箭是按照等动力学取样原理收集高空大气中固体微粒样品的一类取样火箭。该火箭的设计需要考虑取样飞行马赫数、取样扩压器的流量系数和气动特性、取样过滤材料的效率等特殊要求。我国在70年代和80年代研制并发射成功挺进一号甲和挺进二号两种型号的等动力学取样火箭。
The Isokinetic sampling rocket is one kind of sampling rockets that collect solid par-ticles contained in upper atmosphere based on the isokinetic sampling principle. Some special requirements must be considered in rocket design, such as the flight Mach number during sampling flight, the flow coefficient and aerodynamic characteristic of sampling diffuser, the efficiency of filter material and others. In 70's and 80's two isokinetic sam-pling rockets named TJ-1A and TJ-2 respectively were developed and launched successfully in China.
