Hi John, remember i have that gear pump i can send up to you if you want to test it out and have a IC leaf blower motor i think it works. That motor could be use to drive the pump Cheers, Mark.

Nice run there John. How do you think this run went? I notice one of the top right black face gauge was bouncing a bit on shut down.
Cheers, Mark.

Hi Mark Yep , sure did , well onto a second go around the dial , LOL, I couldn't find the needle the first time I looked , I wasn't expecting that much increase in thrust :-) I've pulled the engine apart and alls well inside , still the original soot on the front wall and not much combustion happening any earlier than before , the evap tubes have a tad of "colour" . Good to see 55,000 on the tach , so a tip speed ~1640 ft/sec , my "design " 1700 ft/sec if we use tip speed squared for increasing P2 it should give another 7.4% ,1.074 X 3.75 = 4.02 PR ,.......just right :-) I'll make a new flametube thats more sympathetic towards the evap tube placement , currently a number of tubes have "cold" air blowing onto them , it'll also have the "thimbles" in the front wall to get air and fuel mixing earlier , I'll have a think on the thimble desiogn to see if I can make something thats easier to manufacture . I think I can call it a successful testrun, a few more steps forward towards her 250 lbs of dry thrust, she's rumbling nicely . Cheers John Good for you John Your hard work will pay off eventually looking forward to see that 250 lbs of thrust and then with AB OH MY Cheers, Mark.
