摘要

结合动态入流空气动力学，对多旋翼无人机进行了实时飞行仿真。目前的组合程序包括旋翼/机身空气动力学和内饰分析。旋翼空气动力学是建立在动态入流空气动力学基础上的，适用于多旋翼无人机的分析。本仿真采用了合适的机身空气动力学公式。对爬升和前飞进行了配平分析，确定了无人机的物理约束条件。在此基础上进行了仿真，并与飞行试验进行了验证。结果表明，将动态入流空气动力学与飞行仿真相结合可以提高飞行仿真的精度。利用该方法对影响无人机性能的动态特性进行了研究。

Real-Time Flight Simulation for Multirotor UAV Integrated with the Dynamic Inflow Aerodynamics

A real-time flight simulation for multirotor unmanned aerial vehicles (UAV) is performed in combination with dynamic inflow aerodynamics. The present combination procedure includes rotor/fuselage aerodynamics and trim analysis. The rotor aerodynamics is based on dynamic inflow aerodynamics, which is appropriate for the analysis of multirotor UAVs. The present simulation uses an appropriate formulation for fuselage aerodynamics. Trim analysis was conducted for climb and forward flight to determine the physical constraints of the UAV. Based on this procedure, a simulation was performed and validated against the flight test. It was found that the accuracy of flight simulation increased if the simulation is performed in combination with dynamic inflow aerodynamics. Using this methodology, the dynamic characteristics that affect the performance of UAVs were investigated.

期刊介绍： The Journal of the American Helicopter Society is a peer-reviewed technical journal published quarterly (January, April, July and October) by AHS — The Vertical Flight Society. It is the world''s only scientific journal dedicated to vertical flight technology and is available in print and online. The Journal publishes original technical papers dealing with theory and practice of vertical flight. The Journal seeks to foster the exchange of significant new ideas and information about helicopters and V/STOL aircraft. The scope of the Journal covers the full range of research, analysis, design, manufacturing, test, operations, and support. A constantly growing list of specialty areas is included within that scope. These range from the classical specialties like aerodynamic, dynamics and structures to more recent priorities such as acoustics, materials and signature reduction and to operational issues such as design criteria, safety and reliability. (Note: semi- and nontechnical articles of more general interest reporting current events or experiences should be sent to the VFS magazine
