2 kg以内起飞质量的无人机超长续航策略

An Ultra-long Range Strategy for Unmanned Aerial Vehicles(UAV) with Less-than-2 kg Take-off Weight

根据2016中国机器人大赛空中机器人组无人机续航挑战赛项目规则,提出一种新型电动无人机超长续航策略。依据"大马拉小车"的原理,设计更高效能的螺旋桨驱动系统、更高能量密度的电池组以及降低结构质量所占比例的方案,选取更为优化的材料与结构和制造工艺,采用SolidWorks 3维建模软件进行仿真,并通过多次实验验证。实验结果表明:该策略能大幅提升无人机续航时间,有效解决目前电动无人机续航时间短的难题,为电动无人机的设计制造及在更广范围内的应用提供参考。

Based on the UAV Range Challenge,Aerial Robot Team of the 2016 Robocup China,the thesis puts forward a new ultra-along range strategy for electric UAVs.In order to meet the requirements of the contest and address the problem between the range of multi-rotor UAVs and their take-off weight,we design better screw drive system,high-energy density battery pack and a proposal to reduce the proportion of structure weight in accordance with the principle of a big horse drawing a small cart.We have used better materials,structure and manufacturing technique,simulated with SlidWorks and conducted experiments and comparison tests,the results which indicated that the strategy had greatly increased UAVs’flight range.In this way,we have addressed the issue of short range of electric UAVs,providing reference for their design,manufacturing and application in a wider scope.
