Ahhh ! Thank you
I've got a bunch of reading to do I see
the 2 PJ's side by side and useing the intake pulse is close
to what I had in mind so I've got some studying to do !
thank you for the help!

Bob....

So No body has made one of those "T" shaped Pulse jets UH ? wow with all the PJ's out there being home brewed I figured someone would have tried to make one or two at least! ... I guess I am in virgin teortory then and will have to wing it hehehehehe I figure a few basic ideas of CC /2 for the exhos...

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 .... h...

Ahhh ! very good ! thanks for the Info Larry ! My Ramjet looked at one time almost exactly like steves ! ... But I used the conical flame holder and still have it in there... Well, obviously I'm not going to get 200mph air out of my tiny blowers, they don't even come close to a shop vac. so I will h...

Great info there guys thank you ! Ben , I used a blower to blow into the intake of the ram jet but I simply don't know what to look for , to be honnest! I don't know if it will get real loude like a Vlaveless Pulse jet or if it will just have a purdy flame and be running just fine , I am asumeing it...

Hay Bill ! correct me if i'm wrong, but it would seam to me the Augmenter 's dimentions would be directly calculated from the Resonant frequency of the engine ... it just seams natural ! ..but I am wondering how much thrust can be added to an engine by adding an augmenter ??? reason tells me it won'...

But Augmentors require Good quality Cones ! their almost impossable to make out'a scrap pipe ! HAHAHAHAH (perhaps I will finish the Roller I started a while back to bend sheetmetal...) ... Right now I shifted gears and am trying once again to make my ram jet work, knowing what I know now I should be...

Very Cool Hinote !
do you have any pictures of it yet ?
Keep us Posted Please !
Can't wait to hear all about it ! <grin>
C ya !
Bob........

And the 3rd and final , best running of the lot.

...

Here is the 2nd one I built.
....

Howdy All !
here id the 3 Valveless Pulse Jets I have built so far
they all run, but are not State of the Art engines by any means.

Here is the first one.

Mike ! a question for ya ! when running this engine at full blast it sort'a hunkers down like the other engines a bit and realy roars deeper, but after about 1 minute it stops dead.... its easy to re start so I ran it again at full throttle and it ran for about a minute and stopped again, I re start...

Here is the Dimentions of this engine.
C ya !
Bob......

here is a better pic of the girl runnin flat out. I did my calculations and trimmed up the intake and exhost pipes and man does it run good now ! it likes alittle air to get it going, so it won't self start but add the air and crack the propaine and she fires up ( with the sparker going ofcorse) it ...

Seeings as how little thrust can be obtained from these pulsejets I think your right Mike. its like fighting a loosing battle, if you build the Jets big enough to supply the needed thrust then you can't haul enough fuel ! almost pointless ! but where there is a will , there is a way ! .... Yah Bruno...
