Hi Bill Hmmmmm......is right I've a feeling you're going to have to pull her apart to finally solve this one, perhaps its a ball bearing cartridge that hasn't...
So I am starting to design my afterburner for my VT-50. I am curious about what fuel nozzles you guys are using? I know A/B are fuel hungry and I've read where...
I am currently working on getting my spark plug ready to use, and I have built the circuit that is shown in the Starter Pack, designed by Bruce Simpson. I have...
John, One of the great things about this group is the willingness for people to help others. After reading of my plight, Matt has graciously offered to open...
Hi Grant The actual flow you require can be roughly calculated from the actual flow that your combustor is burning in conjunction with your TOTs . If TOTs are...
Hi Grant, Forget using a nozzle. On my afterburner (on a ST50) I used a simple 1/8" steel ring with 8 1/32" holes drilled into it. This allows the fuel pretty ...
Hi Bill Thats excellent news , its not something thats come up before , so I'm looking forward to learning about it :-) Cheers John ... From: O'Keefe, Bill...
That is a good idea. I know my hardware store doesn't have any steel tubing, would Mcmaster have the 1/8inch tubing to suffice the steel ring? I have to go to...
Ah, thanks so much John for setting me straight! It really wouldn't matter much if I use either the steel ring with holes drilled in it or an actual misting...
hi ,either way can be used to deliver the fuel for the ab,just adjusting the fuel pressure will give you the required amount of fuel,this can take a bit of...
Hi Grant LOL... generally I have to construct things that "I can construct", rather than try and make something beyond my capabilities , so make whatever...
Sorry, the video you are trying to watch is only available in Canada. Dang, maybe I'll try a proxy..... ... planet-ma ... with... ... intended ... is ... ...
Hi Nick Received your email , but all attempts at reply kept getting bouced :-( I keep getting told ......... This account has been disabled or discontinued...
Hi Can't help with the electronics :-(( ..... but the spark plug only needs to operate as long as it takes to get ignition of the fuel and/or pilot light . ...
Hi all: I've posted my first video of my project in action on Youtube: http://www.youtube.com/watch?v=FUS2wIXRWIg As you may recall this is a conversion of the...
Hi Bill Congratulations :-)) A "normal" idle temp for the combustor plenum would see ~ 40 deg C - 100 F, just warm to the touch . Just keep the temp under...
Nice Work Bill! Matt www.turbinebuilder.com On Thu, Apr 3, 2008 at 7:31 PM, John WALLIS (Racketmotorman) < ... [Non-text portions of this message have been...
I am not familiar with Bruce's design, but typically, the circuit will have its own (power ground) and a separate high voltage ground. If its a standard high...
Nice job, Bill. Sure is satisfying when you get to see the fruits of your labor in action. Keep a good eye on the temp when running it slow. These critters...
... will heat up real fast when run below several psi. I'm kind of surprised that you didn't see any compressor pressure, as it accelerated pretty well when...
Hi Bill With an "open" exhaust and a TOT of 745F , that then gives you around another 300 degrees of heat energy for making thrust when you add a jet nozzle ,...
John, flights are booked (finally!!!). Gonna be in Oz from 7th to 26th September. Based in Brisbane we'll make a trip to Sydney for a few days so we will...
Well, no worries John, I throw around ideas in my head for weeks before I build them. This is due to the fact that I am in college, and my workshop is at my...
i was just wondering what the applications would be for nitrous oxide injection in a diy gas turbine. i'm shure that it would make a difference in the rpm's...
Hi It'd make no difference whatsoever to rpm , egts or thrust , we already have enormous amounts of excess oxygen in our engines , adding expensive nitrous...
Hi Grant LOL.... what are you protecting the fuel line from ?? .....if its flames ......then won't the "flameholder" protecting the pipe potentially "hold a...
