由于一个项目需要，核心非火箭发射，但是需要火箭发动机，时间紧迫无法自行设计制作发动机并做推力测试，希望圈内高手能够帮忙制作一个精美的发动机并帮忙测试录制视频后发给我。我不需要燃料，只需要测试过的发动机...

没问题吧，我之前做过一个用8gknsb的小发动机，在喷口还用的是粗制滥造的堵漏王的前提下，实测出近30N的推力，不过那时我还没有能收集推力的试车台，只能靠拍了视频目测，接近30N，理论计算出来好像是3...

经过四个多月多的设计，制造和测试，登天-3于2019年2月11日在中山市发射成功。火箭高860mm，箭体外径40mm，起飞质量750g 70gKNSB发动机地面试车，emmmm堵头有点漏气地面开伞测...
