中国研究团队报告称，一款卫星发动机在测试中实现了14小时的连续运行。
这款升级版发动机由位于西安的中国航天推进技术研究院研发。它能够产生750牛顿的推力，原设计运行时间近10小时。
得益于一种新型抗热和抗氧化涂层，该发动机连续运行超过了14小时，且额外增加的运行时间并未以牺牲性能为代价。
相比之下，美制的R-42DM发动机和欧洲的Leros-1B等主流发动机的设计运行时间通常约为7小时。中国媒体于2026年7月3日报道了这一测试结果。

A team from Xidian University has developed a car-mounted microwave wireless power system that kept fixed-wing drones airborne for up to 3.1 hours. The system uses GPS positioning, dynamic tracking, and onboard flight controls to maintain alignment between the emitter and drone during flight. The findings were published on March 25 in the peer-reviewed journal Aeronautical Science & Technology.
