| 摘 要： | 过去已进行过多个机种的自由飞模型大迎角特性试验，但均为单一项目的试验，现介绍了将获取放宽静稳定度特性和气动导数两个项目综合于一个自由飞模型飞行试验项目中的情况，用脉冲升降舵激发起模型的纵向短周期运动，用参数辩识方法获取气动导数，试验结果表明这种方法是可行的，为从事本专业及相关专业的科研人员提供了参考。

| Abstract: | We have determined the characteristics of high alpha for many kinds aircrafts during free-flight models flight tests. But every flight test only includes one testcontent. This paper presents how to determine both the characteristics of relaxed staticstability (RSS) and the dynamic derivatives of an model in one flight test of free-flightmodel. The results indicate that the method is feasible. |
