Hi Guys I've just changed my email address , finally got sick of all the spam advising me on how to satisfy my women better whilst wearing a "genuine" gold...
Joined the gmail club now I see.....lol. Good to know your new address, I will be sending you some updated pics here in a day or two :) Matt ... [Non-text...
... hi mat looks very nice i was wondering how menny rev's you exspect of your powerturbine at it's output shaft ? enny HP calc's yet ? regards magnus...
Hi magnus, The power turbine max output RPM is 3200 RPM. She will be pumping out around 80HP and 250-290 ft. lbs of torque. Matt ... [Non-text portions of this...
Looks good Matt. Why the clutches on the jackshaft? Do you have an oil cooler for the free turbine gearbox? Am I asking too many questions? I’m hoping to...
hi Chris in the uk ,a proban boiler suit is ok to use,not very natty but cheap and quick to get hold of.do not know the regs in the usa ,but it is worthwhile...
hi matt very impressive layout,very well thought out. just wondering why you do not have direct drive from the freepower to the rear axle and cut out the jack...
John and Chris, I will try to answer both of your questions at the same time. The jackshaft is driven by the power turbine at a rate of 2:1. This set up allows...
hi matt that clears that up then :-),nice idea running a alternator.is the clutch pretty beefy to handle that power? regards jon ... jackshaft ... an ... ...
well...a single clutch can handle 12 HP, however, I have two of them paddled together. Even though the power turbine is producing 80 HP at peak, its not all...
Hi Matt She's starting look like she's ready to roll :-)) Just a coupla things I don't quite understand .... How can you be certain the freepower can't...
okay, lets see if I can explain a bit better :) The sprocket on the output shaft of the freepower to the jackshaft (clutches) is a 2:1 ratio. So if the ...
This morning I ran a new FT. To make a long story short, it ran up to almost max power! First time in 2.5 years! I only stopped short of max to take a data...
I have used copper for SI exhaust gaskets with great results. They do periodically require annealing after removal to continue to be serviceable, but that is...
... hold ... No he seems to have dissapeared for some reason, someone thought he had PC problems but that was a while back. Hope everything is OK, perhaps he's...
I don't know if its much help, but the last time I talked to Russ on the phone, he was moving. He was having some family problems. He did say he might "vanish"...
HI, I'm currently building my first turbo jet engine so please help me out. I read the starter pack, but it just talked about the flame tube saying that should...
Hi Matt Thanks for the extra info :-)) If your gearbox has a ~20:1 ratio (if I remember correctly) then that 1100 rpm output speed equates to ~22,000...
Hi Flametube wall thicknesses can be down to 0.5mm-0.020" if using stainless steel , but needs to be thicker if using mild steel and a decent lifespan for it...
Great news Mike! Remember the messed up mangled flame tube I made for my first engine and how good that thing ran? Remember how I could chop the fuel at...
John, Thanks for the input-compliments. I too thought about the problem of the clutches engaging even at low idle speeds. I am hoping that the free power will...
Chris - I think it is all Black Magic! Once I get everything sorted out then I try using a little "engineering" to transfer this "technology" to the T04 and...
Thanks for the information. I used the JetSpecsDesigner program and it said to use a 15" long 5" diameter flame tube. Then at the bottom it said to 1 to 1.5"...
I would not use any sort of "liquid weld" on your combustor. Even on the cold side of the combustor, temps can reach 300 degrees F or more. Most of those...
I agree, I tried a High Temp Epoxy Resin (Really wow stuff) and it didnt work. Took three seconds with the mig (worst bit of weld ever) and it just wont let...
I spoke to Russ today on his friends cell phone and he is still having computer probs . His phone is also web based . So no e mail and no phone. He is hoping...
hi mike looks like all that time and effort have really paid off.that combustion instabilty seems to what i have got on my current ft,but does pass at the low...
