ok, so here is what i have been pondering on... as i see it, there are two separate ways to arrange a dual turbine setup..( working in parallel, or in series)...
Thrust is governed by two variables: how much air mass flow we have and how hard we can accelerate this mass. Accelerating the air mass requires us to heat it...
Hi Justin No :-( Because in a series setup you only have one hole at the front "sucking" ambiant air , whereas with a parallel setup you have two holes at...
Wow John, You stun me once again with facts and figures! I always wondered what your take on an engine like that would be. Still intriguing from a fuel...
Hi Russ LOL... I'll give you some more data in the morning , its my bedtime :-)) Cheers John ... From: Russ W. Moore (USA) To: DIYGasTurbines@yahoogroups.com ...
Hi Russ Heres some more detailed info on a 2 stage'r To save complicating things with intercooling lets use a 2.5 PR across each stage , thats at generally the...
Hi John, Refresh my brain, what do you do for a living? Math teacher? ;-) You sure have a good handle on the theoretical end of how these beasts work. Not...
Hi John, Someday you will have to write down all of your equations for me in a way that I can decipher them and transfer the math to a program similar to...
I'm a high school student looking for something to do over the summer. Without a robot to work on (robotics team) or school, I am looking for a fun challenge....
Hi Rick LOL... I often wish I'd stayed at school a little longer than I did , rather than leaving as a 16 year old more than 40 years ago . Its a case of...
Hi Russ The only problem I found with "equations" , was , I didn't understand what the various components of the equations refered to until after I'd done a...
Hi Folks, New here... I was hoping to build a turbine with a small compact design. I see most people mount their combustion chamber on-end to the turbo...

Hi My name is Dan . I am at the point of my build when I need to attach the bung for a P2 gauge . What is the best location to place it ? On turbo scroll , on...
Hi Dan, I'm Dan too! From what I've heard, the best placement for a P2 pressure gauge is right after the compressor (outlet) on the pipe that goes to the...
I would say take a line from the CC itself at a point where the air is travelling at it's slowest. ... From: montesa321@... Date: 02/05/2007 12:44 To:...
Ryan - Just to give you more info to think about: I have a turbo (43 mm inducer) that ran for years (on propane) with a perpendicular mounted combustor (4.5"...
Hi Dan - Welcome to the group. The P2 take off on my kart is in the side wall of the CC nearing the output (hot) end, near the larger dilution holes. The air...
Hi Mike, Very interesting. Is the flame tube equal to the length of the whole combustor? It seems like that would force all of the air through the flame...
Ryan - The effective FT length (3.5") = FT length minus the length buried in flanges (1/4 + 1/8) for a total length of 3.75". Add to that the thickness of the...
Hi all- I'm new to the group but have been thinking about building a gas turbine for some time. My shop is well-equipped with a large lathe and Bridgeport but...
In the combustors that I have seen, the flame tube is either shorter than the combustor, or there are large (1/2"+) holes at the end of the flame tube. As I...
Hi everyone!! I have come back to build my first GT. I had begun to build one but I fell short of funds and time but now I am able to try again. Does anyone...
Hello all, Just built & tested a new engine. It seems to work well with no over heating problems. Did have problems with the ab but I can fix that. The flame...
Very nice Nick, Interesting design on the evap system, but it does appear to work well. What are you using to start it up by the way? Looking forward to more...
I was reading an article on modern diesel engines. It stated that the fuel pumps were achieving 26,000 PSI and the injectors were piezoelectric. It struck me...
Lookin good H. Certainly worth keeping a close eye on the integrity of the evap tubes after a couple of runs just to make its bearing the strain. Looks like...
