I wouldn't think there would be trouble making pressure in a combustor that is overall near 380mm(14.96")in diameter by 900mm(35.43") in length, with a more conservative tail cross section ratio than the Argus. It may be good to respect LinusN observation that thinner valves should be tested. At le...

We have already planned to block some of the valves to make the intake area smaller. Regarding the valves, I can't really see how they could be too thin. They are thicker than the valves of the original V1, and we have seen no proof at all for them opening fully and getting in contact with the diff...

From some rough calcs the airflow quantity required for this engine is nearly 3 times that of the previous kick engine. That appears to be a considerable amount. I would recommend to apply the diffusor, but with a design that resembles more typical ejector intake designs.(this should help in reachi...

I see a 2 cylinder hydraulic press in your shop that looks like a PACIFIC machine. Is that made by Pacific? I was a service engineer for Pacific from 1971 to 1973. Is anyone on earth doing full time research on pulse jet engines? Now that I am retired I would love to work with somone doing pulse jet...

Hi Here are some clips showing different attempts to get the engine running: http://www.youtube.com/watch?v=qDXCSFc7K_Y Does anyone of the more experienced guys in here get any ideas of what to do? http://translate.google.com/translate?js=n&prev=_t&hl=sv&ie=UTF-8&layout=2&eotf=1&sl=sv&tl=en&u=http:...
