采用改进的准定常气动力和能耗估算方法,对仿蝇布局微型飞行器的结构参数和运动学参数进行了优化,估算了不同尺度样例飞行器的气动力和能耗.结果表明:①仿蝇气动布局更加适合厘米级、毫米级的飞行器,翼展大于3.75 cm时,其性能相对于同尺度的常规布局飞行器不再有优势.②仿蝇布局飞行器的最优运动学参数为:对称转动模式的转动周期为0.2T~0.25T;扑动加减速周期为0.15T~0.2T;平动迎角取值范围25°~30°.增大扑动幅度可以降低扑动频率,但低扑动频率不能产生足够升力时,要减小扑动幅度,增大扑动频率.
The improved quasi-steady aerodynamic and energy estimation methods are used to optimize the structural parameters and kinematic parameters of the fly-layout micro-aircraft, and the aerodynamic forces and energy consumption of the aircraft of different scales are estimated.The results show that: The aerodynamic layout is more suitable for centimeter and millimeter aircraft, and its performance is no longer superior to the conventional layout aircraft with the same scale when the span is greater than 3.75 cm.② The optimal kinematic parameters of the fly layout aircraft are: symmetrical rotation mode Of the rotation period is 0.2T ~ 0.25T; flutter acceleration and deceleration period of 0.15T ~ 0.2T; translational angle of attack range of 25 ° ~ 30 °. Increasing the flutter amplitude can reduce the flutter frequency, but low flutter When the frequency can not generate enough lift force, it is necessary to reduce the flutter amplitude and increase the flutter frequency.
