| 摘 要： | 建立了舰船甲板上直升机旋翼，机体耦合动力学分析模型，导出了其运动方程。无铰旋翼采用当量铰、刚硬桨叶模型，采用准定常理论计算桨叶气动力并计人旋翼动力人流的影响；假设机体是刚性体并在弹性起落架上作六自由度运动。舰船具有6个运动自由度，并考虑直升机在甲板上的不同位置及舰面流场等因素。

| Abstract: | An analytical model of rotor/fuselage coupled dynamics of helicopter shipboard on-deck was presented, and its dynamic equations were derived. The hingeless rotor was simplified as equivalent hinged rigid blade model. Aerodynamic loads were modeled using a quasi-steady blade element theory, and the effect of dynamic inflow on the rotor was considered. The airframe was assumed to be rigid, and its six-degree-of-freedom (6-DoF) model on elastic landing gears was established. Also, 6-DoF model of ship motion wa... |
