Congratulations! Sounds cool so far. And the pipes are definitely of good workmanship.

I am with "tufty": Figures would be nice to follow.

Keep up the good work!

Cool! Very cool!

Nice to see the topic developing! Still there is the 3-D pulse-jet illustration topic. You seem to be quite busy, Forrest?

Indeed, Mike! I hope everything is fine with you and yours! Lately I have not had much time to browse the forum. Only once in a while. Rarely I foundmyself in the position to comment on something anyway. Did you have an indication of the hot spot in the CC as a proportion of physical length? I have ...

Regarding: Rothenburg, "Days of Thunder", 2007-05-18 . Introduction Due I want to keep everything regarding the K-PT 07X-2 engine to a single thread, I decided not to encapsulate it under the "Days of Thunder" topic. At first it is worth to mention that I was able to demonstrate -07X-2 successfully...

Hey folks! So I have been to Rothenburg on Friday, 2007-05-18. It definitely was a funny and interesting time again. It appears like the whole event was organized more professional than last year, so at least I hope this is going to continue in one or the other way. So that the "Days of Thunder" eve...

Definitely. Taking it with me is not much of a problem, and I planned to do so. But it is in question whether I can do some changes to the injector till then or not. From memory: Starting has not been as easy as it should.

2nd Pulse-Jet Enthusiasts' Meet, FRG, 2007-05-17

Hello folks! If anybody is interested in R/C flying of pulse-jet and model turbine powered aircrafts, I would recommend to think about visiting eastern Germany in the end of May 2007. To be more exact: Rothenburg (postal code: 02929) in Saxony, near the Polish-German border. About 180 km south of Be...

Would not (hydro-)dynamic pressure or Bernoulli or gas pressure represent suitable keywords for a first search?

Sadly I cannot help you out immediately right now.
