Pressure gain combustion

John, Thanks for your reaction by PM and now in the thread. I already knew your PJ-prop project and I read your contributions to Luc's "pressure gain now proven" thread. Then I didn't know what pressure gain combustion meant though :lol: Now I know! Appearantly I designed it with this project! :D Bu...

Pressure gain combustion

John, I'll answer you but first let me show what I found the last hour or so: http://books.google.nl/books?id=Ksn4Z1_YQdAC&pg=PA234&lpg=PA234&dq=kentfield+pressure+gain+combustion&source=bl&ots=7N3AGn-wWv&sig=OBqpGWlE9PuiJrN6kNRFwYHYtrA&hl=nl&ei=i_UuSr7dDsSD-AbBiMSmDQ&sa=X&oi=book_result&ct=result&r...

Re: A pressurized environment for the PJ

O.k. can’t keep it to myself any longer. Here’s the idea. Note: If this is a new idea it is an invention of Fedde C. Bleijs, The Netherlands, don’t you walk away with it! :evil: (I’m not talking to anyone particular) pressurized PJ turbine.JPG As you see the pressure doesn’t cause flow in the PJ, if...

Re: A pressurized environment for the PJ

Now first come on with those 4 atm. PJ designs!! :evil: Anybody? :( So could we take two pressurized tanks, one enclosing the inlet side and the other enclosing the tailpipe side? Nop, the inlet also spews out exhaust gasses and the tailpipe also needs fresh air… :( So now what :?: I think I alread...

Re: I knew nothing!

I knew nothing...! but I studied the forum... :wink:

This is not a reaction to f**k you off but more one to encourage you. Most information you ask for, you will find on the forum. And you might learn some extra during the searching! :D

Good luck!!

Re: Calculating top speed on ice...

Hi Anders, I think that with E85 you don't have to worry about carbonisation at all (unless you generate extra extreem high temperatures) :D As stated by me (and challanged after) the carbon is a result of a cracking process. The ethanol though is extremely stable due to the chemical composition and...

Re: What would you pay for...

So I suppose the Thundequaker 5000 pro©! one million pound pulse-jet engine also gives only about 500.000 lbs of thrust?
Very disappointing :x

Re: Thermonese Thrust Test Troubles

M., Sorry. It is 4 bar , total pressure, as I used the word "immerse". Please insert coin and try again. :wink: O.k. you win :( Sorry. I do not use NUDiS . I have never used NUDiS . I will never use NUDiS . No .qsav is available. Makes me wonder. Uflow it is? Or is there more in this wonderous world...

Re: Thermonese Thrust Test Troubles

M., Not ever. Well, not ever, unless Fedde immerses it in his hypothetical 4 bar testing cell. :wink: Not 4 bar, 4 atm=3 bar (in fact 3080mbar), at least in technical terms: Zero bar (overpressure) is still 1 atm. Oh dear, how people can make life difficult… But entirely not important, the idea stay...
