As long as the valve moved to the middle of the motor to stop functioning, but because of inertia, motors exported to the valve will vary between the back pressure which increases the motor to stop functioning, it is possible to return to the pipeline route or valves destruction, must therefore be shown in Figure 5-23 shown in the system Zhongzhuang a brake relief valve.

只要将换向阀移到中间位置，马达就停止运转，但由于惯性，马达出口到换向阀之间的背压将因马达的停止运转而增大，这有可能将回油管路或阀件破坏，因此必须在如图5-23所示的系统中装一刹车溢流阀。

In this paper, experimental study (Ma=2.0 of cold flow) on a scramjet combustor model without combustion was carried on direct-connected facility. The effects of inflow parameter, length of isolator and back pressure on combustor and isolator flow field were analyzed and compared. The flow field of combustor was simulated with CFD software and the experimental results were compared.

文中在超燃冲压发动机燃烧室直连式实验设备上，对超音速燃烧室模型进行( Ma ＝2.0)冷流实验研究，比较了不同的来流条件、不同的隔离段长高比和不同的燃烧室出口反压对燃烧室内部流场以及燃烧室隔离段的抗扰动能力的影响，并利用数值模拟的方法对燃烧室内部流场进行了模拟。
