On www.te-baumgart.de are a lot of beautiful home built jet engines, and I thought one of them had a shaft out of it for driving a model helicopter. JW ... ...
I guess I was very lucky to get my GT running on diesel for the very first time.. Well not the first time because the ignition wasn't powerful enough and the...
Attaching anything to the main gas producer shaft will alter it's balance considerably. No matter how well it is done, it will ultimately fail due to stresses...
Hello Nick, Tuesday, June 1, 2004, 10:05:06 AM, you wrote: N> Attaching anything to the main gas producer shaft will alter it's N> balance considerably. No...
Go for an oversized turbine and housing (like maybe half again over the gas turbine). The back pressure will be little more than that of a decent thrust...
hi there ,i took a pic and posted it in the photo section ,i agree it may be caused by the intake blowing onto the flame tube and blowing the flame across. the...
just a couple of quick quesitons.... has anyone got their mitts on a set of ceramic compressors/ turbines? if so, what're they like? also, is anyone using proE...
Hi JW Carbon will only buildup where the surface is relatively "cold" , if your combustion takes place too far down the flametube , either your fuel ...
There is a garrett turbo on ebay at the moment with a ceramic turbine...looks tempting!. I suppose that as it can handle a greater T.I.T, it follows that it...
Hi Mattie The backpressure (P4t) in the jetpipe of our "normal" thrust engines should be exactly the same totalpressure between the gasifier and freepower ...
Hi Jonboy Now thats carbon buildup :-)) A baffle would certainly be in order . 80 degree might be a bit wide , I use a 60 degree and feel its too wide an angle...
As you can see, the number of turbo maniacs attending next months, 2nd gathering of British enthusiasts is getting bigger all the time. It looks like there...
I am wondering if anyone can simplify the 555 timer ignition circut. All the drawings on here do not make any sence to me. I need to know what parts to use and...
I could build and sell you an ignition circuit if you want...do you have an ignition coil? If so, then about £4-5 should cover it, or I could get a coil for...
When i was shopping for my turbo here in Australia i was told by a heap of people to stay away from ceramic turbines. The reason being that they are more...
it seems the slight performance gain isn't worth the unmanageable failure mode. In a turbocharger they're used because of the lower mass, they spool up faster....
This site shows the engine I was talking about: http://www.technologie- entwicklung.de/Gasturbines/Jurgen_s_Turbine/jurgen_s_turbine.html This has indeed a...
Hi, I think that the atomisation is good, I used a brand new Danfoss 60 degree solid 1.75 gallon/hr nozzle, it sparys a very fine mist of fuel. the fuel...
But the ceramic material is a lot lighter that the super steels (Inconel 713 etc) that are used in the 'old fashioned' turbo's like everyone here has. So when...
I built the system with the automotive coil and the performance wasn't too great, just a low power spark (In my humble opinion). I use a HV trafo of an oil...
I'm in colorado springs, colorado. I have a coil and a few other things. I would much rather find an easy ignition circut copy it and then but an RPM counter...
If you'd like, we can supply you with a simple drawing of an ignition circuit using common / easily found components, ie flasher unit, ignition coil, relay...
The link below goes to a bbc interactive page concerned with renewable energy sources and similar topics. I couldn't help but wonder what goes through the...
It sounds like an interesting idea - but just that, an interesting idea, not a practical replacement. There's no such thing as free energy...my guess is that...
Hi all, Firstly, looking forward to Bovingdon on the 11th June. Secondly, follow the link that Nick gave (2 posts back)you will find a link to a website...
Actually, Chris, you would need more than 3000 hp at the engine to compensate for the losses created by changing the form of the energy. As the wngine's...
Rick, Very true. Nothing is perfect. I'm still learning! I always used to wonder why you needed such a huge diesel engine in a locomotive if all it had to do...
