一架太阳能无人机在四月底至五月初连续八天的破纪录飞行后在海上失踪。这次事故还标志着开创性飞机阳光动力 2 号的过早消亡,该飞机此前曾执行过世界上首次太阳能穿越大西洋和太平洋的任务,后来成为美国军事任务的无人测试平台。
池运行的情况下实现如此高的航空耐力,因为它的翼展长达 236 英尺(72 米),相当于波音 747 大型喷气式飞机的机翼,并且覆盖了 17,000 多个太阳能电池。 Skydweller Aero 公司购买并改装了最初的 Solar Impulse 2 飞机,使其成为“永久无人飞行”的测试平台,能够承载高达 800 磅(363 公斤)的有效载荷。
Skydweller Aero was conducting test flights for maritime patrol mission scenarios with the US military, and the company also holds contracts with the Navy and Air Force.因此,Skydweller 无人机在 4 月 26 日凌晨起飞进行最后一次飞行时,就是以这种能力运行的。
在海军
据 Skydweller Aero 博客文章称,Skydweller 无人机从密西西比州斯坦尼斯国际机场起飞后,飞往参加美国海军在佛罗里达州基韦斯特附近举行的年度舰队实验 (FLEX) 演习。 The Navy’s press release describes the FLEX 2026 event as testing AI and drone technologies for maritime patrols “in the fight against transnational organized crime.”
As part of the event, the drone used radar along with visual and thermal imaging to observe targets on the water during four days of continuous flight, according to Skydweller Aero. It also acted as a flying communications hub for Navy aircraft and warships while supporting AIS transponder-based tracking of ships in the area.
