Would a like-impinging pintle be easier to machine than a liquid-gas pintle?Disclaimer: Static tested over 2000 hybrids, from H to O sized.
Definitely, you can have impinging injectors. One great thing about nitrous oxide is that it atomizes very, very easily because it flashes from liquid to gas in the chamber. I never saw that like-like impinging injectors were substantially better than the the two I described, other than making machining more difficult.
While we're at it, do you use unlike impinging injectors in your tribrids?
