There's sure one somewhere as you can't never get something totally right by simple thinking, but thanks for your comments Larry and Bill!

The first pic looks like it was taken with thermal imaging hehe. 153 pounds LPG bottle? Isn't that big? Anyway, the fuel consumption looks good to me. Congrats! No--the engine looked pretty much like that to the naked eye. The bottle IS big--BTW you can see it in the second shot--it stands about 5 ...

The result of my observations...

Note : This is purely a "guess", there's no theory in what I've drawn. We'd all like a pulsejet to be a simple tube, where air enters by a side and thrust goes out by the other. However, it makes no sense. ......... __________________ Air in |_________________| Thrust out So, an explosion has to hap...

Re: All New WIP Photos Now On Site

OK, I managed to get the minivan working again in record time, for a mere $703.50, and just now I got the Elektra I page updated with all the remaining 'under construction' photos: http://www.cottrillcyclodyne.com/ElektraI/ElektraI.html The next time I post pictures of Elektra I here, there will be...

Re: building lockwood

To roll your cones, make yourself a simple slip-roll. BTW for the doubters, here's a shot of my (now-retired) Kentfield-designed 4-tube project. This engine successfully duplicated Kentfield's efforts by producing 45lbf in an easy-starting, good-running project. The megaphone section was formed in ...

I hope it's gonna turn out ok! Good luck! Avenger - Thanks much. We shall see what the Lord wills for me and Elektra. One important thing I need to do to that Web page is get a big warning box on there about welding galvanized / coated steel. That stuff is very nasty! I really had to be careful ton...

Is that like the SNECMA Escopette, with room behind the thrust recuperator and the main part of the pulsejet?

Yes, true, but I don't think one topic for each forum would be so long to do.

A single topic, with links to confirmed working pulsejets topics would be the simple yet effective way in my opinion.

OK, cause, being interested by model airplanes, I tought it'd be somewhat complicated to get fuel injected by the top of the aircraft (running a fuel line to it). Do you plan to build a prototype after your Elektra pulsejets? (You come up with a lot of desings lol). Actually, one of the best fuel s...
