Re: Tesla Compressor

Larry, I am not quite sure what you mean by “uniform strength” I think I should explain the design a little more as I left out a bit of info last time. They are not quite as flat as it would appear; they have a recess in the middle where I intend to put some air slots and to save weight. You can kin...

Tesla Compressor

After reading Nick’s thread I was inspired to experiment a little myself building a Tesla gas turbine. I decided rather than go strait for a gas turbine I would design and build a small (ish) compressor using disks like a Tesla turbine and spin it up with a rather nice hyperactive nitro engine I hav...

Re: Okay, I think I've lost it

Using electrolysis to create hydrogen would be the simplest way, you will have oxygen come from one electrode and hydrogen off the other (cant remember which is which though) so keeping the gasses separate shouldn’t be to difficult, if you use a sealed tank of some sort as the water split it would s...

Re: New A400M Turboprop engine

Ok, I know this is a lack of knowledge in aerodynamics on my part, but how the hell does a prop like that create any useable thrust? The rotational drag on those must be incredible! I suppose that’s why u need 10,000 horses? Humm, one of those, my nova, now were talking! Just as soon as I save up a ...

Re: A little help needed.

Thanks Viv, more books sound good to me, the more I read, the more I learn, the more chance I have of success. I find that although all the info I could ever want is out there some ware on the Internet, there are so many conflicting ideas and so much crap it is almost impossible to pin down somethin...

Re: Mini N2O gas canisters?

Nope, it’s not that one; the one I was told about is a prototype thing. Incidentally, I actually got to see that one in Farnbrough at an Engineering/Electronics show last year. Unfortunately it wasn’t whizzing up and down the runway, was just posing, hoping for inverters/sponsors I believe. There wa...

Re: A little help needed.

Already on that route, ordered the book from the library last week, could take up to 6 weeks to arrive though, I prefer to have a look for free before I spend any money. The same applies to the engine, I’m not about to go and buy a load of metal without having a solid idea of what I’m going to make ...

A little help needed.

I was hoping someone would be able to help me with a few things on the design of my turbine housing. I have a good idea of how I plan to go about building the engine, but there are a few things that I am unsure about. How much clearance should I have between the turbines and the casing, I understand...

Links?

Hi, it would appear that the link to the links section is a little out of order, when I try to click on it, it just says that it don’t exist. Is my computer being an ass or is it undergoing maintenance of some description?
Would like to see what it has to offer.

Re: Mini N2O gas canisters?

I thought about this a little today and I wouldn’t be quite so quick to dismiss it. What I am about to suggest is backed up with very little experience so correct me if I am wrong, but from what I can understand of a pressure jet and the idea you propose is, It is the rapid expansion of a gaseous fu...

Re: New Members

Thank you for the warm welcome, I mean re-welcome? I have a few other little stories like that, but I am a little too ashamed of to admit to right now, perhaps another day, after a few beers. My wife often asks me why I do such things, to which she generally gets one of three answers, sometimes to m...

Re: Mini N2O gas canisters?

I think there is a kind of dragster that is powered by something similar, from what I was told it basically has a tinfoil tube, at one end N2O is injected and mixed with old chip fat, then at the other end there is a specially shaped steal cone of some sort that stops the fiery bit advancing up the ...

Re: Mini N2O gas canisters?

Ok then? My point was has anyone tried to use these before? Seeing as they are quite cheep and easy to get hold of I thought they might make a good source of N20 for testing of an idea or something along those lines. Or perhaps should anyone one day attempt to send something skywards, an easy compac...

Mini N2O gas canisters?

Hi This may be subject already well covered but being new here and without spending several hours going threw the forums its hard to tell. Basically I was talking to a friend of mine today who mentioned something that gave me an idea. You can get these little 8 gram bottles of gas that are used to w...
