摘要
在单旋翼涵道尾桨直升机的非线性全量飞行动力学数值模型的基础上,提出了求解配平问题的一种混合算法,研究了地面效应对配平的影响。以某直升机为算例,在无地面效应和考虑不同悬停高度时,分别进行了初始参数进行了配平,配平计算结果与地面效应的理论相符合。
In this paper, a fixed numerical method is carried out to trim the helicopter based on a nonlinear numerical model of flight dynamics of a single rotorcraft with ducted tail rotor in horizontal flight. In hover, two situations: with ground effect and without ground effect are considered when the helicopter is trimmed .The result conforms to the ground effect theory.
