文中着重介绍了投影图像法在立式风洞中的应用,伞弹稳态扫描试验的试验方法、试验设备、图像采集与处理方法、以及伞弹稳态特性研究。研究结果表明:实验系统工作正常,测量系统测试到了伞弹系统的弹体姿态及扫描角等参数,弹体平均转速的测量结果和外场试验的测量值基本一致。

This paper emphasizes on the application of projection image method in vertical wind tunnel, and the test methods, testing e-quipment, image collection and processing method of Parachute-Bomb stable sweeping tests, and the study on the steady state characteris-tics of parachute-bomb. The result of the investigation indicates that the system of experimentation can work properly. The parameters such as the missile body attitude, the scanning angle of parachut-bomb system and the measurement results of the average rotating speed of pro-jectile which were tested by measurement system were consistent with the results of outfield.
