中国首次具备直升机垂直升降风洞试验能力

人民网西安11月16日电(记者王泓漓通讯员兰小红、胡兴雨)今天,驻川某所Φ5米立式风洞直升机垂直升降试验台研制成功,标志着我国已具备承担直升机型号的垂直飞行性能试验能力,这填补了直升机垂直下降风洞试验的空白,建立了开展旋翼复杂流动机理研究的试验基础,对确定直升机的“安全飞行范围”起到重要作用。

为建立与Φ5米立式风洞配套的直升机垂直升降试验技术,该所于2008年启动该试验台研制项目。直升机垂直升降试验技术是自主研制直升机不可缺少的风洞试验技术之一。课题组使用Φ2米旋翼模型完成了引导性试验,旋翼轴转速达到2100转/分。

通过开展旋翼模型垂直升降状态模拟、旋翼流场显示等工作,课题组解决了试验台振动、姿态角精确控制等问题。引导性试验结果表明:该试验台运行可靠,达到预期技术指标,部分性能指标优于国外同类型设备。

据悉,该试验台主要用于开展旋翼模型的垂直升降带动力试验,能够承担型号研制中的直升机垂直升降性能试验及机理性研究试验。
