I checked that, 148mph is kinda wimpy I think I could get that in the 1/4 mile pretty easily. As for a record I'd just petition Guinness directly. FIA rules need a serious overhaul and as my friend says- why the hell do we care about some Frenchmen in a Winnebago and their opinions on our performance? Outlaw racing spoiled me. I would only run front wheel drive on the salt. I'll stay where slicks work  Record for the cheapest 150 mph dargstrip ride. Imagine the fuckery you could pull grudge racing this thing! |

   Hi Chris, Good to see you back on this project, i to have one of these starters my plan is to use for a free power gearbox project for my jet bike. Is that air brake (comp wheel) press on the shaft? my thinking is to remove or machine off the turbine wheel and hook up a 4th stage turbine wheel onto that shaft and machine up a bearing carrier for the output shaft on the gearbox side. Cheers, Mark.. |

Hi Chris
LOL......you'll piss it in using steam/water :-)
Could you give me the exit diameter of those 4 nozzles , you mentioned that the throats were ~0.125" are the exits ~0.375" for an ~9:1 A/a ratio ??
Cheers
John

Mark, me thinks they put those 2 together for keeps, if you want the shaft i would surgically remove the wheel ie no load it's spindly. Shaft and turbine wheel same piece
John, glad you asked was just getting ready to put it back together. Where the oval cross section starts it's about 1/4" and tapers out to about 11/32" on the other end of the oval. I think the day i drill the nozzles out will be a day when I'm desperate for thrills.

Hi Chris
Thanks for the size , sounds like the actual divergent portion of the CD nozzle isn't fully expanding the gases within the nozzle so as to prevent possible problems with shock waves, allowing the last bit of uncontained expansion between nozzle and turbine wheel inlet.
Have you considered "burning??" the air being pumped by the compressor wheel , if your actual rpm are down to around half original specs due to the slower steam velocity , that comp will be producing maybe 7 - 10 psi of pressure , just right for an afterburner ..................you'll have shaft horsepower as well as some flames ;-)
Can't wait to see this beast "steaming" along .
Cheers
John

Damn, that was a good idea, i wish i didn't cut the compressor off!
Honestly, for what I'm doing, i want to keep this balls ass simple. I'm starting to consider frame design, I'm set on one rear wheel, edge of traction acceleration 2 tires never agree where that is. Not sure if I want rear suspension it will be for drag strip use just not sure of th best tire yet. I don't want tire shake.
I would like to lay on my belly as close to the ground as possible, just enough room for a huge boner (not cast aluminum). I figure the steering will be a tiller on each spindle. Foot rear brake and foot throttle, hand brake up front. I want just enough flex and/or suspension to filter out the violence and really let me feel what the car is doing. Feel if it's getting light n whatever. I'm gonna go pretty fast on the cheap. cheap thrills!

this project is cut back a little, getting ready for Bensendays in wachula fl. Me n Richard are going, a few friends may follow . march 26-29 Gyrocopter junkies n propeller heads. I'm bringing the van, the jet bike and the cheap ass $6 chopper to putt around on. Big freakin airport party, don garlits museum not to far, orlando not too far. this show is building up, I need to bring something to look at. these guys treat me real well!

Hey Chris, love the drawing, like the idea of the aluminium box section. I would shift the tank back a bit if some thing goes wrong, you may want to have kids in the future... If it is going to the drags only, I would not worry about suspension. Why 2 wheels at the front? When you draw the steam off are you going to just fire super heated water over the turbine or draw live steam from the top of the tank or have some type of nozzle to allow expansion before it hits the turbine? Ian... |

superheated water right into the turbine is simplest. 2 wheels at front so we don't have to deal w roll, just yaw and maybe pitch. We're not competing so we can afford the weight 2 wheels w huge brakes as well as chutes. Some of the places where we may run this may have less than a perfect surface, we're considering sand dragging it too or maybe land speed. Also, even if I just mount some dampening between the motor pod and main frame, it will help bad stuff like tire shake from breaking things.
The tank will not breach, the valving and piping will. The body will be designed to keep the tank put and allow any broke lines/fittings to vent out the back. I'll design it so it will have to be a pretty bad wreck before the tank even gets a scratch.

Hello, everyone. My name is Keith and I'm a dragaholic. Specifically of the motorcycle persuasion. I've been invited to participate in Mr. Krug's little foray into the wonders of steam turbine power. I'll be providing some insight into the single traction wheel drag racing end of the machine by piloting it and giving him some feedback. He'll be keeping me safe from the hot, hissing spinning bits.
Honestly, he had me at the minivan.

Welcome human test subject! Me n Richard have a test subject! Seriously Keith is bringing great insight into being an external pilot and managing a one wheel rear drive. Keith will pretty much dictate overall layout, weights and balance and setup, We'll translate his desires into a plan that utilizes our resources. Richard will handle data recording/safety monitoring and some traction control experiments... I'm gonna make power until Keith says stop.

Hi Chris
Now you treat Keith nicely and don't put him in danger ;-)
