直升机旋翼阵风响应研究

THE PRESENT ACTUATION OF GUST RESPONSE RESEARCH OF A HELICOPTER ROTOR

简要综述了当前直升机旋翼阵风响应的理论研究和试验对比研究的成果及发展方向，事实表明，旋翼的阵风响应是一个比较复杂的动态现象。它是研究旋翼在遭遇到一定形式的阵风后，旋翼由阵风诱导的响应参量的动态变化规律。它不仅影响直升机的驾驶品质，而且影响直升机的疲劳载荷和强度，其研究目的不仅在于进行理论分析和试验对比研究，而且还在于研究阵风减缓的机理和装置。阵风响应的研究对于具有较高动应力与振动水平的无铰旋翼的设计尤为重要。

In this paper the present actuations,efforts as well as development ofgust response of a helicopter rotor for comparison purposes in theory analysis and expe-rimental efforts are simply reviewed.The fact is that the gust response of a hehcopterrotor is a complex dynamic phenomenon.It is to investigate the dynamic law of severalresponse parameters of a rotor exposed to types of determinative gust input.It not onlyinfluences ride quality of helicopter but contributes to structural fatigue load andstrength.The objective here not only is to investigate comparision in theory analysis andexperimental efforts but is to investigate theory and devices of gust alleviation.It is spe-cific important that research of gust response for design of hingeless rotor configurationswhich have higher dynamic stresses and vibration levels.
