The Recipe would produce something like this for a single body.

Using 2 blended bodies has it looking more like a typical thermo jet.

Hello Ganuganu

From an 5 inch dia. engine it must be possible to get 30 pounds of thrust I think. It looks like a scale-down of Metiz his design and that one was around 40 lbs. Try it and you will know :wink:
But I hope you will know after this time on the forum good fueling is very very important.
Why are you not going for one intake?
Why not chosing for a straight exhaust?
If you could answer those questions, I think you're more on the way in your learning-process than scaling other designs.
(Not trying to blame you, I've also some scaled drawings, which I tried to run In Nudis and Uflow, but that didn't work well for me :| )
...It's better to generate heat efficiently, than recover it efficiently...

yes thats the scaled down version..and my answer for your questions now..i WILL say whatever i know..if we use multiple intakes there WILL be more proper mixing of air fuel mixture..more than straight pipes these conical types produces more thrust..i think this WILL be the answer..

I am trying to build a valveless...I have been using PyroJoe's recipes (Thanks soo much!) I like the valveless more than the valved ones. I don't really have much of an Idea of what to do for anything (Fuel systems, mounting, etc.) all I know is that you can use propane and brake line for the fuel and light it with a torch. also, what is the thickness of the steel, and is it black, galvanized or stainless? I really like this design of a thermo-type, and with 2 intakes facing backward. any help/advice would be much appriceated....thanks.
