近年来,在军民用应用前景强烈刺激下,多旋翼无人机已经成为航空航天领域的研究热点~([1-2])。六旋翼无人机是多旋翼无人机家族中的重要一员,它可以悬停和垂直起降,还具有控制简易、维护方便等优点,适用于非常复杂的任务环境。旋翼无人机气动特性研究是无人机设计过程中的重要环节~([3-4]),目前对旋翼式无人机气动特性的研究主要针对直升机,对六旋翼无人机气动特性的研究少见报道。本文首先发展一种基于动量源方法的计算流体力学方法,
In recent years, under the strong stimulation of military and civilian applications, multi-rotor UAVs have become the research hotspot in the field of aeronautics and astronautics ([1-2]). The six-rotor UAV is an important member of the multi-rotor UAV family. It can hover and take off and land vertically, and has the advantages of simple control and convenient maintenance, and is suitable for a very complicated mission environment. The research on the aerodynamic characteristics of the rotor UAV is an important part of the UAV design process ([3-4]). At present, the research on the aerodynamic characteristics of the rotor UAV mainly focuses on the helicopter. The aerodynamic characteristics of the UAV Research rare report. This paper first develops a computational fluid dynamics method based on momentum source method,
