摘要: 介绍了在航天空气动力技术研究院FD-10低速风洞中建立的风洞虚拟飞行试验系统,和对风洞虚拟飞行试验技术进行了验证性研究的情况.研究的目的是探索风洞虚拟飞行试验技术的原理和关键技术,包括组合式滚转轴承系统和舵面作动系统的缩比模型以及悬挂支撑系统技术.分别进行了模型滚转运动和偏航运动的风洞试验,对模型姿态随舵偏角变化的实时响应进行了风洞试验研究,验证了虚拟飞行的可行性,为建立生产型风洞的虚拟飞行试验装置打下了基础.Abstract: lt is introduced that the virtual flight testing system built in the FD-1O wind tun-nel, and the test techniques was investigated for its validation. The purpose for this study is to pursue the principle and key techniques including combined roll bearing, fin actors and cable sup-port systems techniques. Wind tunnel tests are conducted to test the model rolling and yawing re-spond to the fin deflections. Thought wind tunnel tests. it has verified the feasible of virtual flight testing and some experience was accumulated, this, established the fundament for establis-hing test apparatus in the productive wind tunnels.
