摘　　要：低速空降风洞试验的一个重要目的是研究伞降人员在离机初期的运动姿态和空间轨迹,考察伞降人员的离机安全性。从不带伞空降风洞试验出发,分析归纳单次出舱和连续出舱空降风洞试验中的一些关键技术,包括试验方法的选取、相似参数的确定、空降模型的设计加工和调整技术、载机支撑方式和支撑干扰的影响、空降模型出舱姿态的控制、空降轨迹捕获和分析技术等。进而初步探讨带伞空降风洞试验的一些特有问题,旨在为进一步发展低速空降风洞模拟试验技术提供支持。One important objective of airborne tests in low-speed wind tunnel is to obtain the model＇s moving posture and motion trajectory of the early stage of the airborne flight to analyze the security of the parachutists. The key techniques of airborne tests in single and continuous separating from the port are summarized based on the airborne test without the parachute on the model. These techniques include the selection of test methods, the determination of similar parameters, the processing and adjustment techniques of airborne models, the mod el support methods and the effect of support interference, the control of airborne models~ moving posture when they separate from the port, the techniques of airborne trajectory capture and analysis, etc. Further more, the problems of airborne tests with parachute on the model are preliminary analyzed with the aim of technique sup- port in further development of airborne tests in low-speed wind tunnel.
