Watch: Astrobotic's Chakram engine aces record 300-second hot fire

Astrobotic broke the record for the longest duration hot firing of an RDRE, with a 300-second burn of its Chakram prototype engine.

据太空启动公司称,其中包括破纪录的 300 秒燃烧–这是迄今为止 RDRE 发动机持续时间最长的热点火。在测试期间累计的 470 秒热点火过程中,两台发动机均未受损。

Chakram 的高效引爆过程

传统的火箭发动机利用的是减磨,而 RDRE 与之不同,它利用的是围绕发动机圆体旋转的超音速爆炸波的快速能量释放。

据 Astrobotic 称,这种引爆过程可将比冲或发动机效率提高 15%。它还能提高推重比,使设计更加紧凑。

在最近的测试中,Astrobotic 的 Chakram 发动机各产生了 4000 磅(1800 公斤)的推力,总运行时间为 470 秒。
