摘要 为了解决搭载光电平台的无人机在飞行时受的阻力影响以及如何提高无人机的续航能力,增加无人机的飞行时间,针对此问题,设计了一种结构简单的无人机载光电侦察平台升降机构。光电平台工作时,通过升降机构伸出机外;光电平台停止工作时,收入机内,从而解决阻力的影响,另一方面,通过采用减轻升降机构重量,从而提高续航能力。升降机构采用碳纤维铝蜂窝夹层复合材料作为支撑板的主体材料,同以前应用的铝合金材料相比较,重量减轻4.5kg。经过多架次外场飞行试验,取得了良好效果,无人机续航能力有所加强。 In order to enhance the ability of continuous flight of the unmanned vehicle and solve the resistance of the aerial photoelectric imaging platform,a kind of structure to carry the aerial photoelectric imaging platform as it ascend and descend is proposed.The platform stretch out the outside of the airplane cabin when it begen to work and take back inside airplane cabin when it stop.By this way,the resistance problem of the unmanned vehicle from the aerial photoelectric imaging platform is be solved.On the other hand,it help to improve the ability of continuous flight of the unmanned vehicle by reducing the weight of the structure.The carbon fiber aluminum beehive mezzanine compound material has been used as the main body of the structure.It reduced a 4.5 kg weight compared with aluminum metal alloy material.Many flights experiment enunciation,the ability of continuous flight of the unmanned vehicle is strengthened.
