|| Re:Mini Myers Initial Tests -- Long Post
Thanks and congratulations! Great to see someone trying those odd ancient designs to see how they worked. Engineers used to be smarter back then because they had to be, without the amazing tools they can wield these days. Also, everything was on smaller scale back then and you could afford to experiment. Today, being too bold is simply too expensive.
Concerning your test -- it confirms my fear that there is no way that machine could have sustained self-ignition. Of course, with some simple electronics, this is not a problem. As for working only with forced air, well, so many proven designs will do that until you adjust them precisely, let alone something as far out as the Myers. It is probably due to the very inefficient shape of the jet.
Frankly -- even though I was the one advancing the theory that it works on teh choked jet principle -- I was amazed that the thing worked and that there was no appreciable blowback through the front jet.
Are you sure it was not due to the air pressure -- you know, ram pressure preventing the expansion of gas towards the front, like on a pressure jet?
Thanks again! A grand experiment!
