摘要/Abstract

摘要： 在分析半转翼运动模型和翼面气流特点的基础上，建立了悬停和前进两种飞行状态下的半转翼升力计算模型。根据半转翼的运动特性，推导出适合半转翼运动的升力计算解析表达式。结合半转翼样机参数，应用导出的理论公式和基于CFD软件的数值仿真模型，分别计算不同飞行条件下半转翼的升力，获得半转翼悬停和前进两种飞行状态下升力变化规律。理论计算与数值仿真所得升力曲线的对比验证了升力估算解析法的有效性和可行性。研究结果可为半转翼飞行器的参数设计与升力预估提供理论指导。

Abstract: The lift models of HRW in hovering and forward flights were proposed based on analyses of the motion models of HRW and flow characteristics on the surfaces of the wing. According to the motion characteristics of HRW, the analytical expressions of lift were further derived. The lifts under different flight conditions were calculated using derived formula and numerical simulation based on CFD software respectively with same HRW prototype parameters, by which the changing rule of HRW lift in hovering and forward flights could be also got. The comparisons of lift curves between the theoretical calculation and the numerical simulation demonstrated that the analytical method to estimate lift of HRW is effective and feasible. The research results mentioned above may provide important theoretical guidance for the parameter designs and lift prediction of the HRW air vehicles.

Key words: half-rotating wing(HRW), hovering flight, forward flight, lift estimation
