I can see where Johansson is coming from - no real referance books etc out there.( as in modern ones - pulse jets as I
understand it have been 'frozen' in time since the 40s-50s).
My Turbine study books are absolutely chocablock with turbine who,what why, when stuff and theory etc etc.
The only reference to pulse jets is a few sentences that basically amount to...
" ..used by the Germans in WW2 ...very loud"-Yep that's all folks.
But I do find the 'very loud' bit rather cool... :lol:

So a book about a 'frozen in time' jet engine - in particular the valved pulse jet?
It would be nice to read about the Soviet developments mentioned in the book.
As it about pulse jets for model aircraft there perhaps would be no
mention of modern development of valveless pulse jets.
Still - it would still be a good read and any knowledge would be great.
Apparently if the book is successful they will translate it to english.

Yes, very nice. I know what you mean. Far too much voodoo to making a really good one. I don't think I'll ever understand it fully. Same goes for t-jets. Too much math.

Not quitting, I'm just on hiatus with the clock thing and some other more understandable endeavors. Twould be nice to do something meaningful with a pjet someday...
