摘　　要：本文介绍了利用旋翼试验塔进行全尺寸旋翼无地效试验的情况,包括试验系统组成、试验方案、试验内容及状态等,并将其试验结果与有地效试验进行了比较。试验表明,在旋翼试验塔进行试验能够很好的满足旋翼无地效试验的要求,所得结果有效反映了旋翼的无地效性能指标,并提示在同一地效高度下地面效应对单位功率产生的额外拉力基本上恒定而不随功率状态变化。This article introduced a full scale OGE(out of ground effect) rotary test on the rotor tower;include the system configuration,test scheme,test items and statuses,etc.A comparison to the rotary test rig result had been made.Based on the test result,it can be conducted that the rotor tower is a valid manner of OGE rotor test and the test result of OGE parameters are satisfied for engineering requirements.It is also shown that the ground effect produced almost the same extra thrust per power unit and is not varing with power or thrust.
