介绍了巡航导弹对转桨扇的风洞试验结果,对一个直径为0.62m的单排叶片和一排叶片后面带一排对转叶片的桨扇组合模型作了颤振试验。试验目的主要是研究当前排叶片颤振时,稳定对转后叶对前叶的影响,结果指出,后排叶片对颤振前叶有一稳定效应。
The wind tunnel test results of the cruise missile on the propeller fan are introduced. The flutter test is performed on a propeller-fan combination model with a row of blades 0.62m in diameter and a row of blades behind the blades. The main purpose of the experiment is to study the effect of stabilizing the posterior leaflet on the anterior leaflet during the current row of leaf flutter. The results show that the posterior leaflet has a stabilizing effect on the anterior flutter leaflet.
