摘要
根据影响螺旋桨式长航时无人机和喷气式长航时无人机续航性能的不同因素,分析了机翼面积(翼载)、展弦比、尖削比、后掠角等参数以及翼型对这两种长航时无人机续航性能的影响,所得结论可为长航时无人机的设计提供参考。
The endurance performances of propeller-driven unmanned aircraft and jet-powered unmanned aircraft depend on same factors. Based on these, the effects of reference wing area (wing loading) , wing aspectratio and sweep angle on their endurance performances are analysed. The results give a reference to design long endurance unmanned aircraft.
