Re: Now It Can Be Told ... Cyclodyne Revealed

"" Did a working prototype ever get built? "" I had two thoughts when I saw the anatomy of your engine neither was the above. One was "oh that's what I invented that fan spray fuel injector for" * Two was "I am not immediately in love with this design, It MUST be good" * It started life as a low flo...

Just referring to the device in question, I long ago came up with a different geometry my self. Weight...

My current build uses head pressure to suck gas out the tail to increase blow.

Re: Anyone *build* a cyclical flow jet engine?

I suppose I should note at this point that my, {( very unproven ) but almost plausible}, own designs, require a reservoir to collect and cool ( cooling is vital ) the recycled gases, further I would make a point to say that in many if not most cases this added infrastructure is a big hit on the weig...

Re: Pulse-jet Thrust issues

I would have to agree.

It appears to barely idle. Not to thrusty like that.

Re: Anyone *build* a cyclical flow jet engine?

My current build will re-direct some of the compression chamber gases to improve engine performance. At my current rate ( read as pathetic rate ) of work first fire will be some time late next year. It is not a new idea at all, and many of my notebooks have designs that include this feature, sadly t...

Re: Will this work? Sudden brainstorm ^^

If you hooked every thing just rught, it might work, just long ebough to melt the can. Thin aluminimum placed under that amount of thermal load would melt in two seconds or less. I suppose it depends on your definition of Work . I would not do this. nor would I reccomend it. You would be creating a ...

Re: Please think of Mike Everman

I have been watching this fire closely. I some how missed this post until now. I was/am aware of your proximity and have been quite concerned. Glad you are well. I hope home will greet your return, intact and inhabitable. From our vantage point in the Sanfernando valley this looks like a preview of ...
