摘　　要：电磁弹射是一种极具发展前景的新型弹射技术,现有的电磁弹射系统主要用于大型战机的弹射。为了实现中小型无人机利用电磁弹射起飞,本文提出一种双线圈耦合多级电磁加速弹射方案,并详细分析了双线圈耦合多级电磁加速的工作原理。针对无人机弹射的实际需要,分析确定了弹射系统加速轴轴长的计算公式和弹射系统的关键参数计算公式。基于上述原理完成了实验样机参数的确定,设计了相应的机械结构和控制系统,并进行了多组验证实验。所研制的样机采用8组400V680μF电容加速,2组400V680μF电容制动,弹射速度可达57km/h,发射效率达到24%,能够完成小型固定翼无人机的弹射起飞。Electromagnetic ejection is a new type of ejection technology with great development prospects. The existing electromagnetic ejection system is mainly used for ejection of large fighters. In order to realize the take-off of small and medium-sized unmanned aerial vehicles by electromagnetic ejection,this paper proposes a two-coil coupled multi-stage electromagnetic acceleration ejection scheme,and analyzes the working principle of dual-coil coupled multi-level electromagnetic acceleration. According to the actual needs of the UAV ejection,the calculation formula of the acceleration axis length of the ejection system and the calculation formula of the key parameters of the ejection system are analyzed and determined. Based on the above principle,the parameters of the experimental prototype were determined,the corresponding mechanical structure and control system were designed,and multiple sets of verification experiments were carried out. The prototype developed is accelerated by 8 sets of 400 V680μF capacitors,and 2 sets of 400 V680μF capacitors are braked. The ejection speed can reach 57 km/h,and the emission efficiency reaches 24%. It can complete the ejection of small fixed-wing UAVs.
