Wow, how about that polish?

Polish is shiny !
How in the world , you made that polish shiny, Bill !?

I don't know. Maybe it's just me, but, the forum doesn't feel the same anymore. There's been lots of misfires, lately. I'll bet M. is really impressed with the massive yawn he got, when he offered to post dimensions for an efficient alternative to the L-H valveless type. Also, my effort to try and ...

Larry, That must be misunderstanding. I have never used UFLOW and was damn confused how could you guys get it going. It was a simple inquiry and request for clarification. Speaking for myself I greatly admire your work, design and testing of new concepts. Your participation in this hobby is essentia...

Mikhail,

Pretty impresive list of projects and acomplishments !
I am glad you are OK, once before I inquired about you
and found no response.

I think pressing two halves of these engines is the way to go.
I am also going to build some valved jets soon.

Ed

Larry, or anybody else, knowlegable in UFLOW ! I have few questions. Where do all these input data come from ? Like wall temp, initial temp and initial pressure ? Friction is set to Zero !? They all differ for each individual pipe section, why ? Are all these estimated values ? How could the output ...

This is the finest engine I have seen so far !

Are the idividual sections spot welded ? It looks that way.

Hybrid motors are lot safer than solid boosters. Almost any solid combustible matter can be used as a fuel grain. I.e. rubber or paper tubes, standard ABS and PVC plumbing drain pies, asphalt - just name it., high density PVC is the best. I helped to launch 8 ft tall rocket on ABS 3 inches pipe and ...

Luc & Viv,

It appears that you, guys have a serious ego problem.
How old are you ?
Need help ?

[quote="Al Belli"] The center seam is high temperature brazed, and should be welded over for operating at pulsejet temperatures. Al Belli I have used these cylinders for different purpose and found that brazing at the bottom and the mid section was a problem, since the brass material contaminated TI...

I have built five diferent engines with chinese style tail pipe, and all of them run very efficiently with strong steady roar and always adequate thrust. I mix scaled first two than I went on my own, with different designs and never failed me. Larry, I thing scaled aircraft with pulse jet is a pipe ...

Relax, Ed. We're doomed anyway. Have a beer. That's what I'm doing. My daughter has brought me a sample case of 12 different Belgian beers from the trip to the European Softball Cup. Damned if they don't compete with good Czech beers. Different, but just as good. Life is nice. Short but nice. Bruno...

What realy gets me now, that Army Corps of Engineers pumps that filthy water back to the lake, creating more ecological dissaster. That water need to be treated and detoxed before it goes back. But, NO ! It is political expedient just to "drain and clean" New Orleans to report fast progress after su...

Larry,

You need to start cutting stainless steel, CR built engines will never last
more than few runs. It is a vaste of valuable work time.

Ed

Bill, I would give it rear intake .94 times the mid section diameter, terminating at one third of total length and the thing shuld run just fine. Just looking at it, I am pretty confident that would do the trick. I have a similar engine running w/o problem. Otherwise you would have to change the len...

Larry,

Sorry, I dropped the ball on this one, for obvious reason -
Annular engine.

I have one more thing in the mill and right after that I"ll get going
on your FWE desig.
