Thanks for the help. I'll keep trying. The rotor freed up when it cooled - some sort of expansion problem - could well be the problem Good luck with the...
Hi all, I am building a alcohol fuel based gas turbine, so my question here is: What can i use as fuel nozzle? I have many ideas: Buy a carburetor from a...
For powering wheeled vehicles...the best option for GT power is the series hybrid...drive the genset with the GT...drive the vehicle with the electric...
Hey guys, I made an ignition controller using one of the schematics on the ignition circuit link (sixth one on the list : "Ignition circuit using the 555 timer...
A 2N3055 transistor takes a lot of current, at the base, to drive and I don't think that the 555 can drive enough current to saturate the transistor. You would...
Gas turbines are fuel hungry creatures. A carb will not work as it pre mixes the fuel and would not keep up with fuel requirements. Look in the rule of thumbs...
you could always try a heat sink. but i agree it shouldn't get too hot with that circuit. -Grant ... schematics on the ignition circuit link (sixth one on the ...
Hi guys i was looking for parts that you listed and have hard time locating any of them , could you provide me with any links beside ebay? or i would be...
Not sure if these guys will have exactly what you want but its worth a shot. Avon Aero US Everett Aero UK Akron Turbine Group US Turbine By Gateways US I know...
Thanks i been sending emails to multiple turbine sources :) hopefully i will find something :) i will check german ebay (i speak some german i grow up 20 miles...
hi can anyone help me in the quest to find an appropriate pump for the turbocharger i have been looking all over and can not seem to find something that suit's...
Hi Mark :) Any chevy 350 pump will work only problem is that has to be mounted inside tank , it has bypass valve build in it so it will pump 40 psi at 500 rpm...
Why do you intend to use alcohol? It will take nearly twice as much alcohol as it would if you were to use either Jet-A, kerosene or diesel fuel. Also, as it...
Hi Tom Before you do anything you need to know exactly what the mass flow is and how much thermodynamic energy you have down stream of those two turbos . ...
hi oil pumps are the easy bit,driving them is the problem !!you can use a power steering pump or a hydraulic gear pump,just use a pressure relief valve and use...
Or you can bypass all that headache and go with the popular shurflo pump. Its a 12v DC diaphragm pump, and all in one package. Cheapest place to get them is...
Thanks again John :) I kind of thought that is what could happen if i get too small or too large turbine :) But choices are limited and i rather go with ...
Hi Tom, You will want to take compressor pressure/combustor pressure, TIT, TOT, and if possible jet pipe P2. As for the water injection. This usually involves...
Hi Matt How would you meassure combustor pressure ? isnt too hot for any sending units to survive? ... TOT, and ... intake air ... too ... about ... im ... out...
well, you can get a good general idea of the pressure by placing a pick up in the diffuser tube before the combustor. It should give your a fairly accurate...
Thats exactly what i thought but i got confused for a while :-) ... pressure ... [mailto:DIYGasTurbines@yahoogroups.com] ... TIT, ... air. ... or ... first ......
Hi Tom P3 (pressure leaving the flametube ) can be several percentage points lower than P2 ( pressure outside/arriving at the flametube ) as we need a pressure...
Hi Tom LOL.... Yeh , we can always "fill" that extra capacity if we've got it :-)) Forget about water injection until your engine is well sorted , it...
The propane doesnt have a true nozzle. It's just a Pin valve that i threaded into the end cap. So its opening is just pointed straing at the opposite end of...
Hi guys: Today I spun my VT-50 conversion project up for the very first time; there's a story to tell though.......... Having just completed my oiling system...
No. you don't want the nozzle to spray the propane straight down the combustion chamber. You'll have problems getting ignition (and it pushes the flame further...
I read that part of the Started pack, but I thought that was for a propane setup only. I just plan to use the propane to ignite the Diesel fuel - then shut...
I don't know what country you are in. Here in the USA trigger coils used to be available from a number of sources. Radio Shack stores all used to stock them....
