Open source confessions of an "Old Space" engineer.
Wednesday, February 10, 2010
I've been testing the Franken motor as well as another igniter for a different application. Finished upgrading the test stand hardware and software with flow meters for both oxidizer and fuel. That has already been very useful as I was able to accurately determine the O/F ratio the igniter is running. It will light as rich as 7:1 but runs very rough. Smoothest operation seems to be right around stoichiometric at 10:1 or a bit leaner.
I've also been working on an avionics experiment that is coming up this spring. More on that to come soon.
