ULA has the 5H25 engine and hydrogen pump on display at their Space Symposium booth:
All that hard work developing the engine and piston pump and they end up a permanent part of a ULA static display?!?? That can't be a good thing for the Lynx program..
Easy on the doom and gloom
. The 5H25 was a development engine that we tested in 2015, and while the technology is similar, it isn't part of the Lynx program. This engine and pump were built for ULA as a subscale demonstrator for the 8H21. Also, as I understand it, the hardware isn't a permanent display and we sent it to them just for the conference.
