Hi Ash a = Force divided by weight X 32.2 , so your acceleration will be 6 div by 215 by 32.2 equals about 0.9 feet /sec/sec , so after 20 seconds you'lll...
There have been 110v power systems available for decades that utilize the stock alternator. Many were marketed under the name Power Converter. These were just...
Hi Firstly, between 125psi and 250 psi fuel pressure , your fuel flow will only increase about 40% even though pressure has doubled . Secondly , are you...
John, thanks for info, Current i do have a jet nozzle on it, its size is 4 1/2" down to 3". Sound appropiate? I will try working up on nozzle size and see what...
Hi You really shouldn't be having oiling problems , the positive gas pressure on the seals means they're actually trying to stop gases getting in , not oil...
I know this topic has come up quite a bit, but I am a little confused. On free power turbines I have seen everything from complex gear reduction systems to...
Check out Don Giandomenico's site http://rcdon.com/html/experimental_projects.html look at the GR-5 and GR-5A. He uses a axial flow free power turbine with a...
Hi Matt Theres a few ways you can go about it . Firstly the complex gearbox route , which will provide the best horsepower for mass flow rate , pics of my...
Thanks for the replies. Don's site is good, but a little more involved than I would like. John, I really like your set up. My turbine is based around a T04. Do...
Hi Matt A TO4 would get you going :-)) The shaft I used is a very common Cummins wheel , about 4.7" overall dia , with a 3.5 inch exducer , nice thick shaft...
Thanks for the reply john, I am really getting the idea of it now. So you basically were just using another turbo charger, without the compressor side, but had...
John, thanks for that input. Ran a few more trial runs. Went from a 3.5 gph to 5 gph nozzle and was able to get around 22 pounds of boost, at 130 psi true fuel...
... A corollary that may shed some light: I am a little confused. On internal combustion engines, I have seen everything from a one cylinder two-stroke to a...
I had the same problem as you are. The problem is that the volume of fuel you are putting into the c.c. is not burning quickly enough and the flame front is...
Hi Russ, It has been a while since I have been to DIYGT but on my first GT i was starting it using LP gas. And also on the jet kart I am using gas as to light...
Hi all, Just got my turbine running, but I am having a few problems with it surging. It runs fairly well up to about 5psi but as it approaches 10psi it gets...
Pretty much have to use MHD for that, I think. It's been done, doing it well is a SERIOUS engineering challenge. ;-) (And I'm looking forward to the day...
For a power transmission, I was thinking could you not use the gearbox from a small scooter or moped and adapt it? Chop off the crank case and mount the small...
Hi Matt Yeh. its basically another turbo with a kart sprocket replacing the compressor wheel, the only problem with using a "brass bushed" turbo instead of...
Hi Our combustion is a fairly violent process at times and can give rise to slight "fluttering" of a P2 gauge , mine does the same thing at times , but because...
what angle is your fuel nozzle? i have used a 45o nozzle on mine and the combustion was very rough ,moving to a slighty wider nozzle seemed to reduce it. this...
jon, i've been using 80 degree hollow cone nozzles. I did try full and semi cone nozzles, but flames would come out the exhaust. I may need to look at...
John, my engines thrust is unknown at this time, but i dont think its over 20 pounds, but then again, thats just a guess. It takes about 40 to move my test...
If nothing else, it would have a decided "cool factor" to say we have a MagnetoHydroDynamic generator among out group! Fred ... From: Bruce Bostwick To:...
Hi Matt With TOT's of only 420 , "C" I gather , I doubt it would be surge , especially if it came off a diesel engine and it didn't have a wastegate attached...
Hi Monte Check your combustor to air delivery tube point , is there plenty of room for the air entering the combustor to move past the flametube . If you look...
Hi Sal Great minds think alike :-)) That was the direction I was going with next years project I was thinking of using the whole engine , perhaps a single...
Hi Ash, The Photo's section should be ok now. I had to remove someone's folder as it contained pics of humungous proportions which ate up the remaining space....
I added more pictures of the Solar T41 in pieces. These are from the orignal teardown/inspection before I ran the engine for the first time. You will have to...
