The invention discloses a method for designing a high-speed multi-rotor blade, which comprises the following steps of: firstly, limiting the approximate range of the blade size through known basic data and expected data to obtain a stress balance equation of an unmanned aerial vehicle, then, giving enough specific blade sizes which accord with the limited range, and comparing expected performance indexes to obtain the stress balance equation of the unmanned aerial vehicle. And screening data from the given blade size, performing adjustment in a random crossing manner, performing screening again, continuing for multiple times until an expected performance index can be obtained, and if the expected performance index cannot be obtained, increasing the initial specific blade size data size, reducing the discharge amount of screening each time, and performing the screening process again.
本发明公开了一种高速多旋翼桨叶的设计方法,该方法中,首先通过已知的基础数据和期望数据限定桨叶尺寸的大致范围,获得无人机的受力平衡方程,再给出足够数量的符合限定范围的具体桨叶尺寸,通过比较期望的性能指标,从给出的桨叶尺寸中筛选数据,经过随机交叉的方式进行调整,再次进行筛选,如此持续多次,直至能够得到期望的性能指标,若不能获得期望的性能指标,则增大初始的具体桨叶尺寸数据量,降低每次筛选的排出量,再次执行筛选过程。
