Re: A necessary criterion for pulsating combustion

Whether you want will look true this expression? Whether value will lay in limits from 0 up to 2? I think that IF heat of combustion of fuel about 4*10^7 J/kg this inequality loses sense - expression will be obviously more than 2.0 And I do not see physical sense in the resulted expression. Probably...

In Russia in 1942 !!!

I saw the old book. See the pickture. This valveless PJ engine is similar to the engine of Lockwood, but has been developed and constructed in Russia in 1942 !!! These engines intended for increase in speed of planes (bombers "Pe-2"), but had bad efficiency (related to rocket engine). This engine wa...

Re: Scotland, pulsejets and freedom ! (and some help please)

So much for freedom. As if I looked like Osama! HI Petiot! :) freedom... :) Increase the charge of air. Use a usual torch (not an electric spark plug) in a tail pipe for Ignition. (cautiously! It is dangerous!). The torch should be long and strong. Good luck! I agree with Pieter :) WBR, Dima :)
