Messerschmidt

I don’t had any problems with downloading it and unpacking it in windoze.
It put it up on this link temporary for every body who want it, just open it in your browser and save it.

Re: Suggestions

I wish I could come up with more, but old posts are really hard to locate. Larry if you Google for it and ad this (site:www.pulse-jets.com) in the Google box your only search this site. Or ad (site:www.pulse-jets.com/oldforum) to only search the old forum. Or just use the Advanced Search Option.

valves

I always wondered or a piston could be used as a valve, the same as a two stroke engine does. I have the materials but not the time,(and other priorities) to try it myself. The piston could be supported by springs (car valve springs?) of the right strength so its resonate at the same frequency as th...

thermoacoustic links

Milisavljevic you seem to be busy with some very interesting stuff, however I can not make out of your short description, what exactly you are discussing at Nasa Ames. Anyway here are some links about thermo acoustics. http://www.lanl.gov/mst/engine/ http://www.aster-thermoacoustics.com/results/p1.p...

thermo acoustics

Here is a link about thermo acoustics, and how promising this field of research is.
I have a lot more links about it, if anyone is interested.
I think it has a lot in common with the acoustics of pulsejets.

dyna jet fogger

Jerry is the noise off these Dyna jet foggers the same as from a Dyna jet pulsejet, or is it much less.
Is the noise a real problem for users or is it acceptable.
I ask you because I think you have a lot of experience with them.
Would it be a big improvement to reduce the noise much?.

Mark
This organ uses cryonic temperatures next to heat, only its not based on the Rijketube but on thermo acoustic tubes, also very interesting and maybe this tubes will be the cooling method of the future.

Pyrophone

I only imagined that Rijke tubes could be used for something like that.
Only find this links hours ago, its difficult to imagine something what not already was somebody’s thought before.

Hydrogen

I even read somewhere that by expanding the high pressure Oxygen from such a system, they ware able to use that energy and cooling to liquefy the Hydrogen, don’t can find the link so fast.

how i compress it is actually a secret at the moment untill i can get a patent on it and to store is simple one dive tank for the oxygen one lpg tank for the hydrogen You don’t have to compress it, it seems that electrolysis ask almost the same current and voltage under different pressures, so th...

Nudis

Hallo Graham I never could get NUDIS to run because I didn’t had a C:\ disk. This happened during a reinstall of windows, everything else worked fine, so find it to much work to reinstall again for NUDIS alone. Getting interested again after this post, I mounted a directory with the letter C. And ...

This can easily be corrected by implicating the chances I brought forward earlier. I don’t blame mike for just doing it, you never now if the changes are any good.
