Re: Spring Cleaning

Eric, Wasn't it Bruce S. who designed the home made cruise missile? You should send that to Masterplans, I mean, not the plans but the real thing :lol: Apart from intentions, would be a nice project! :D Back to the PrJ: You building a custom build for me will be way beyond my (very poor :? ) budget....

Re: Turbines driven by pulse jets

Viv, Really curious where we are going but please keep the last question for me. If I answer that one well the patent is mine!! :lol: :lol: :lol: Just joking I have a set of questions for you (or anybody else) as well: http://www.pulse-jets.com/phpbb3/viewtopic.php?f=6&t=4631&p=62889#p62889 If you a...

Re: Two stroke diesel, turbo compound engines

Viv, Kinda following up on your story: Let’s imagine two four stroke (preferable diesel) piston engines. For both we replace the first part of the exhaust system with a chamber. For one engine we install at the end of the chamber a nozzle. For the other we install a small turbine, or an adapted turb...

Here's a nice laser scanner setup

Think this one should be here to. Here's a nice laser scanner setup. You can get respectable results with the free version and a cheap laser from a level. You can even use a shadow line for a scan, so you could probably get respectable results outside using a thin, straight stick and the sun. http:/...

Re: Turbines driven by pulse jets

....., now take off one nozzle, looks a bit like a valveless pulse jet in simple form Viv Is that a question again? Even if it's not, lets try.. gasses traveling in both directions but more to the open end, the following vacuum sucks in fresh air through the nozzle while gasses are still leaving th...

Re: Lockwood simulations, wow

But you have to admit that they are nice as simulations, even if they were simulations of my bowels! :P
Although its looks like my bowels are pulsating a bit more :?

I've sent the guy a comment on youtube, hope he reacts

Some more about PDE, but the first one looks like PJ to me?

Re: Spring Cleaning

Hi Eric,

Are you selling the pressure jet as well? Any idea about the price?

Btw, I bought a cd on Ebay at Masterplans, it has your PJ calculator on it.

Re: Turbines driven by pulse jets

Viv, Is that a "to be continued" question or a "let see how many dummies there are on the forum" question? :lol: Let me try. I would expect a rise in pressure, thus and in temperature and this situation lasts longer. At the same time we will see an decrease of gas speed in the 3 inch pipe an increas...

Re: "Afterburners on valveless pulse jets

Take a look at Eric Becks website, Beck-technologies.com, if I remember well. You will find the answer, and pictures, there.

Re: Two stroke diesel, turbo compound engines

Hi Viv, I also have some nice ideas, that I will probably never execute, around regaining temperature losses from piston machines using steam and turbines. Already done etc, etc, but my ideas don't include an added steam engine/turbine. :?: :!: Thus it can be used in cars with minimun weight and eng...

Re: Caged Ball Valves

Hello all, Normally wandering on the valveless forum but this topic attrackted my attention because I've also been thinking about this problem (never build something though). Do you guys now that there are ceramic ball bearings? These balls are lighter :D and heat resistant :D :D :D Also there are (...
