摘要
无人机电磁弹射技术是一种非常有应用前景的新型弹射技术,与传统的无人机液压/气动弹射技术相比具有一定优势。总结了电磁发射技术实用化面临的难题,归纳了无人机电磁弹射技术有别于一般电磁发射技术的显著特点:弹射频率低、弹射质量小、弹射速度低、弹射动能小等,列举了几种典型无人机的弹射数据,并具体计算了赫尔墨斯450无人机的电磁弹射数据。无人机弹射起飞具有的这些特点,是无人机率先实现电磁弹射的前提与保障。
Electromagnetic catapult technology of unmanned aerial vehicle（UAV） is a new type of catapult technology with wide use prospect.Compared with traditional hydraulic / pneumatic ejection techno-logy of UAV,the electromagnetic catapult technology has a certain advantages.The difficult problems confronted with practicability of electromagnetic catapult technology were summarized.Different from common electromagnetic launch technology,electromagnetic catapult technology has following obvious features： its launch frequency was lower,the launch mass was smaller,the launch speed was lower and its launch kinetic energy was lower.The catapult data of some kinds of typical UAVs were listed in this paper,and the electromagnetic catapult data of Hermes 450 UAV were calculated.Equipped with these features,catapult and launch of UAV are the premise and guarantee of initiative realization of UAV electromagnetic catapult technology.
