摘　　要：投放试验段是某超声速风洞的一个特种试验段,其投放机构是实现风洞模拟试验最重要部件。通过有限元分析对投放机构的强度进行了校核;采用双级伺服油缸驱动迎角机构,解决了投放机构安装空间小、气动载荷大、迎角范围宽、精度要求高的问题;标模试验表明,投放机构各项设计指标满足要求。The launching test section is a special test section of a supersonic wind tunnel. Its launching mechanism is the most important component to realize the wind tunnel simulation test. The strength of the placement agency is checked using finite element analysis. The double-stage servo cylinder is used to drive the attack-angle mechanism, which solves the problem of small installation space, large aerodynamic load, wide angle of attack and high precision. The calibration model test shows that the design indicators of the delivery mechanism meet the requirements.
