【摘要】 为了满足型号研制需要,在Φ1米高超声速风洞中开展了动导数试验技术研究,研制了一套自由振动动导数试验设备,可进行俯仰/偏航动导数试验。通过10°尖锥标模试验验证了设备的试验能力,结果表明:试验数据与国外文献结果吻合较好,该装置是可靠的,可以满足需要。更多还原

【Abstract】 In order to meet the needs of project development , we carried out an investigation of dynamic derivatives test techniques in Φ1m Hypersonic Wind Tunnel and developed a free oscillation derivative testing equipment , wich can undertake the pitch/yaw dynamic derivative test . Then the capacities of the equipment is verified by the 10-deg sharp cones standard model experiments. It shows that the results are in agreement with the literature , and the device is reliable to meet the actual needs.更多还原
