Great Job

Wow Mike, that's awesome! Seeing that video almost made up for the fact that I drowned my truck tonight... Image
Great work, job very well done.

Bruno, you must have better sources than I do, I've been looking all over for more information on Tharrat's pulsejets. (Unsuccessfully) Do you have any more tidbits you feel like revealing? I'm planning to make my first attempt at a Tharratt-derived design this weekend.

Nice work! Pulsating w/ forced sounds like you're definitely headed in the right direction. I can't say that I've got any personal insight into your situation (still learning) but your situation DOES sound very similiar to a thesis I just finished reading. The author constructed a scaled down (4-inc...

Well apparently I can post, I just can't add attachments, and as soon as I try to add an attachment I can no longer make that post. (ie I have to start over and create a new post) Not sure what's going on, but I worked around it. Check out my post in the vavleless forum for some junkyard wars footage!

Lockwood Video - Pulseboat Action!

My roomate yelled at me to turn on the TV tonight, and look what I found. I missed the first leg of the race, during which there was some sort of mechanical failure, but during the second half the lockwood worked great, and propelled the boat to victory. Is it just me, or is combustion happening in ...

Can't Post

What am I doing wrong? I tried to post to the valveless forum, and I get the message "No Post Mode Specified." Heh, the real kick will be to see if I can post THIS message!

Okay, maybe four sentences next time, but any more than that and I think it would start making less sense. :-) Anyway, thanks for the info. I did come across the Gluhareff pressure jets while googling, the G8-2-130 doesn't look very big for the claimed 130lbs of thrust, what kind of fuel consumption...

THANK YOU!

Awesome!!!!!!! That would be so great! If you want to contact me off-board my email is pj AT dipsomania randomtexttofoolthestupidspambots dot net. I'm working on the paper now, and won't have a copy for review for approximately four weeks. But I'll give you a heads-up when it's getting close. In the...

How does it work?

Anybody have a three sentence explanation of how this works handy? A google search didn't help me out much. Also, couldn't the "flame holder" be just that? Can't you use a screen to stop a flame from propogating through a flamable mixture? Maybe understanding how this works will explain why the flam...

Valveless Pulsejet, 100% Effective?

I was browsing patents this afternoon and came across this one, in which the author claims to have working models of a valveless pulsejet with ZERO backflow?!? Interesting read, and I think enough dimensions are given to build one. Not to mention the construction isn't that complicated. Too good to ...

Technical Reader Volunteers

Greetings all, I am a pre-graduate student at the Oregon Institute of Technology (USA) and am attempting to write a technical report on valveless pulsejets. Although I haven't completely decided on a topic, I'm currently looking at exploring a particular pulsejet design, (Foa or Tharrat) analyzing i...
