Rotary valve pulsejet?

[dominik]

Hi John,
interesting finding. Due to my experience with those noisily tubes I guessed it would have instantly died.
Maybe on a very late point I give it a try, but no real planning to do so.

EDIT: After further consideration I wonder if a turbocharger turbine can also be considered as normally
driven in a "pulsed" mode? E.g. a 4 stroke 4 cylinder engine driven at (lets say) 5000 rpm would 
(depending on the crankshaft) create a more or less pulsed exhaust stream with a frequency of 333hz.

I’m much more interested in the resulting thrust (and fuel consumption) of the controlled valve version.

Small update:
The parts for the rotary valve have arrived and look nice:

   Hi Dominik,
     Have a look at this book,

  www.scribd.com/document/142357899/German-Jet-Engine-and-Gas-Turbine-Development-1930-1945

 It has loads of information on the pulse jets that the Germans developed during WW2 including details on a rotary valve version.

Hi,
that book sounds very interesting. Thanks for the advice.
I found some general information about rotary valves on page 253.
Is there futher information on rotary valves in the book?
