摘要 对在 4m直径旋翼 /机身组合模型试验台上进行的非定常气动载荷试验结果进行了分析 ,试验完成了总距、周期变距突增对拉力和力矩的影响。本文还对试验结果和理论计算结果进行了对比分析 。 The analysis of unsteady aerodynamic load test carried out on a 4 m diameter model of rotor test tower is presented. The affect of the rapid increasement of the collective pitch angle and cyclic pitch angle on the rotor thrust and moment is shown. The contrastive analysis between the experimental and theoretical results is compared and an analysis conclusion is given.
