T shaped Pulse jet?
Posted: Sat Jan 26, 2008 12:42 pm
After studying Bruno's artical on improveing the Pulse jet
I got to wondering about 2 combustion chambers
and one tail pipe....
He mentioned that they made a "T" shaped Gas generator for turbines a long time ago that were of this configuration but they had valves in them ...
So I am wondering .... has anyone ever made a 2 combustion chamber Pulsejet yet ?
the idea Bruno had was to alternate the fireing of the Cumbustion chambers from one side to the other and use the explosion from one side to compress the fuel/air mix in the other side before it was ignited... seamed like a perfect way to up the compression on a Valveless Pulse jet
... though Bruno mentioned that the one that was built and ran, it didn't run as planned. sorta like a moped that backfired everyonce in a while HEHEHEH
....
but the idea is so sound I can't get it out of my mind.
its a perfect way to compress the fuel air and increase the thrust output of a valveless PJ... there has got to be a way to get one of these things to run!
...
So I am thinking just a simple "T" shaped PJ....
nothing fancy the top horizonal section would be the cumbustion chambers with their exhost faceing each other
and the lower extension of the "T" would be the exhost
if a simple "Ugly stick" approach was used and just get the thing to fire up perhaps cramming in enough fuel /air would get both sides to fire automatically... but I'm just guessing
...
it seams a waste to me to have the Answer to the ailing low thrust valveless Pulsejet right in our hands and not be able to get it to run ! or ...run correctly.
... anyone have any ideas on how to do this "T" shaped PJ
before I start welding again?
I figure I'll just weld up something and see if it runs if not then I will know what doesn't work and go from there
hehehehhe
...thats obviously not the most efficient way to go about it
but as far as I know the idea hasn't worked yet anyway.
so anything goes !
your comments appreaciated
thanks !
