Turbine engines

[turbine_doc]

Anyone interested in building a gas turbine powered jet boat?
You donate the hull with jet pump.... I will donate the installation and the engine. He who has the most interest in it at the end can buy the other guy out.... or something!

[LaserModVee]

Someone better jump on that one!
That sounds awesome.
Don't turbines cost tons of $$$$$. I think I remember reading somewhere in the range of $100k USD on offshore applications.
Of course you wouldn't want that much money in a jet boat.
Can any jet pump handle the power a turbine produces?
How much HP?
Have you done this before? Pics?

I think this sounds like a really cool way to go!

[turbine_doc]

320 hp. turbine engine modified for marine use.(By me)
Yes done it before but only on the big (50ft) ones with the higher dollar engines.

No pics just yet.... give me a month or so... or wait to see us on Powerboat telivision..... the manufacturer tells me they are going to so a piece on the boat when we take it to Lake-X for trials.

(Twin 1500hp gas turbine engines in 50ft cat. Merc.#6 dry sump speedmaster drives etc. etc. LOTS OF FUN!!!)

As for the small boats... you can see an example of one (Squirt 1) at the Nye Thermodynamics web page. I didn't have anything to do with that one... but it will give you the general idea.

www.nyethermodynamics.com

I can do the engine for about $5000 USD

[eautosales]

i might be interested if i can go along to lake X

[Techno]

If possible I would use it in place of an OB. I'm assuming its light enough.
300 horse isn't that much for any inboard, jet or prop, Of course you don't have the major wieght they usually have. The boats are still built to take it so they are heavier.

It also has the changability thing. You take the OB and the other guy takes the boat.

[TTriton]

I have spent several hours on your web site before.. I never knew that you were here.. Didn't you make a turbine jet boat for river racing?? I belive I remember that one was made form all aluminum..


I've long dreamed of a large offshore cat boat for high speed reponce and to be able to tow with it... I would love to be able to cruse down to Cuba at 100mph and be able to tow back a 60foot hatteras or bertram...

Wanna put a turbine a a Hydrostream Valero YT. I just blew my motor. Looking for formula one v8 Can you give me some details?

[laser]

I love the idea of a turbine, but instead of a jet, how about an arneson (spelling?) surface drive?

Not that I have one, darn it. It just seems if your going to go to all that trouble, might as make something fast. :)

[filter]

they make the Arneson drives. Hey I think this combo would work on my boat!

[turbine_doc]

Makes a great combo. you need a crash box in between though or all you get is forward. (Realy fast forward... but just forward)

[FrenchPhil]

Found a great turbine site with marine applications : COol intro

http://marineturbine.com/turbine.html


What do you think of that outboard ?!

Phil

[timucin]

turbine doc;

how much does a complete system including 2000hp turbine engine+crash box /tranny + and arneson drive (asd-8/10 )costs? all used?
do you have acces to all necessary parts?


i am wondering too much about turbine engines and planning to have a turbine powered boat for future but i dont know too much about them.actually i know nothing about them except
''turbine engines are much lighter and powerful ''
what are the disadvantages of them?
are they hard to maintain?
is it hard to find parts?


it would be very nice to hear any idea or experience .
thnx in advance...

New Arneson 12,000-16,000 Used if you can find one about 5,000. Turbine will run ya about 15,000 -30,000 used if you can find one that is in good shape ( good low hours on blades ) gas consumption is a lot and the reinforcements to the standard hull are rediculously time consuming. Better to buy one already done.
Better of sticking with an outboard or jet for the money. ORrrrrrr go buy a Bat boat. Good luck and don't let the net bugs bite you in the ass.

[timucin]

filter ;
this is very strange look at the prices i get:
complete boat with 1400hp gas turbine:18,000usd
1300 hp gas turbine good condition :25,000 usd
1450 hp turbine : 270.000 usd ?!?

i think the best way to own one, is like you said ; to buy a complete boat

[filter]

motor and the outdrive. These Arnesons are expensive but they are built like a brick ****house. The turbines are from some gov. auction and someone probably got them ran thru by some company. If you do not maintain the blades they will stretch and touch the housing of the motor and explode. There is a lot to these than you might expect. Talk to someone who has rebuilt them and get the facts before you go down this road. this is a good idea but a lot of maintinance and risk in my opinion. I would be concerned with the rotor in the turbine as these can cause problems after so many hours of use. This is still a very reliable motor but remember the maintinance and who is going to do it.

[klem]

did this project ever get off the ground?
How much does 300 hp turbine weigh?
Tom

[Houston Propeller]

we also repair turbine buckets and segments, gas and steam power as well as props,and yes this is very expensive,as well there are so many more safety factors to be considered.

[hi strung]

he goes by laketrash

[Riverman]

Klem,

The turbine engine they are probably speaking of is the Allison 250-C18, available as military surplus under designation T63-A-700. This engine weighs 136 pounds and will produce 317 HP at 6056 RPM output shaft speed. These engines have been sucessfully installed in both jet boats (jet-jet??:) and with outdrives.

On http://www.turbineboat.com/ they have a video of a turbine powered cvx. Its pretty cool. Plus a Baja. Check it out.

[Boaterbum]

Hey, I wonder if I could get any deals on turbines!!?!?! I work for a company, doing Quality Control Inspection, we are, as far as I know, the SOLE manufacturer of the Compressor Cases on General Electric Aircraft, BMW Rolls Royce, Solar, Allied Signal, and several others! Maybe I could get in touch with them, I want one in my truck!!!!!!!!! hehehehehe Hey, who sells Turbine Powered Boats? Smaller, not tthe mega Yachts?? Just want some eye candy!!!!!!! Later all.....

[Rich Owen]

Check out www.turbineboat.com

[Boaterbum]

Thanks, gonna take a look there.... later.....

[Riverman]

For anyone interested in turbine boats, this website is a must see. An old jet boat converted to turbine, and a far more elaborate (and faster) purpose built unit.

www.nyethermodynamics.com

[mrcrsr]

i worked on the uss taylor(ffg 50) as a gas turbine technician and am federally certified on mainteneance on them- we had 2 ge lm 2500 engines(dc 10 engines adapted to marine use) they were rated at 21500 hp each, feeding one shaft(20:1 reduction), input rpm was 9600 rpm, output was 180 shaft rpm, speed was 44 mph in a 450 ft ship(3800 tons), the problems w/ turbines are poor fuel efficiency at low speeds and getting rid of the hi volume of the 1400+ degree exhaust temp discharge- the best source for a turbine are surplus helicopter turbines, there is a place in the midwest that sells themm for 5000$ and up- next problem- how are you going to reduce the high rpm to something that is useable- rpm output of these engines is probably over 12000 rpm so some kind of reduction gear will be required and turbines are most efficient at full rpm- it is an intersting proposition and one that i have been thinking about- maybe all of us working together could get this to work... any suggestions????

[Riverman]

Have a look at Mark Nye's site in the post above. He has built a couple of turbine lake boats. He also sells adaptor and braking kits to couple the engine to the jet pump.

The output speed on the Allison T63 is 6056 rpm if I remember correctly. This is reduced from an N2 speed of about 30,000 rpm. The N1 speed of the T63 is 50,000 rpm!!

So it is quite doable - for cheap too!

[rock]

Several months ago I spoke with Chub of Stroker Boats in Tennessee and he invited me to come see his Bell helicopter engine he was mounting on anoutboard exhaust housing and to my understanding running a stock lower unit. If anyone knows if that ever happened, it would be cool to know results. If I get a chance next week I will call and find out.

[mendo]

Here is a pic of one,

Looks good, they say it works.

[pumpshock]

From what you all have sayed these sound pretty amazing, they have power in both rpms and torque, how small do they come, could one be put under the cowling of a 40 hp outboard with a jet? lol

[Riverman]

No way you can put a cowling over a turbine - they need too much air and run way too hot. Don't forget that a turbine has no cooling system, if the turbine outlet temp (TOT) is 600 C, that could be the outside temp of the engine casings.

[pumpshock]

i was looking at the pic that mendo posted and it appeared to have some type of cowling. But anyway, is there a smaller turbine that would fit that type of application. I would be very interested in something like that.

[mendo]

From what I heard that one did not get the speed that they were hoping for. I hope that they keep trying, it is cool to see other stuff. Yes, the cowling is HUGE!

[pumpshock]

So what about my Q, is there a small enough turbine engine to work on a modified 40hp outboard?

[Rampager]

Back to the origional topic question, is this offer still up for discussion?
Im in the GTA and have just aquired a rather serious jetboat hull. I have a motor and pump but I'd be interested to hear more details about this ????

Cheers

[Riverman]

I have sent you a PM.

[filter]

can be cooled with pickup tube flowing water into exhaust stream with a electronic backup to flow when idling. Use a chemical spray nozzle from an implement company, these are low pressure nozzles. A 1996 lincoln mark 7 cooling fan (125 buck from ford)(switched) pulls 6,000 CFM and this could be modified to cool housing set to a relay also.

[Techno]

To answer how small. They make them for model aircraft so pretty tiny.
I think there is a gap and then the lawnmower size.

[Gas Turbine]

I paid 8k for the Lycomming T-53 shown here, and 9k for an Arneson 17-20 drive, that wasn’t new, but never installed on a boat. Another 7k for the out-of-stock Rogers hull, and about another 3k in miscellaneous expenses.

Labor was about 1200 man-hours.

Take care.

Tell me THAT thing doesn't look deadly! :O
Wow that is really in your face so to speak. What kind of #'s are you getting? Did you do all the fab yourself?
A driveshaft loop on the drawing board I hope? hehe

Very nice boat

Hello,

Took me a long time to find you. Yes I am interested in building a turbine boat. I have what I believe to be a good market for them if I can get one out and running. I need a turbine engine installed that is plug and play in nature meaning one that the average guy can get in and start and run without being a rocket scientist. What I need is something in the range of 400 hp with jet drive in a bass boat hull. What do you think? At least we can email for awhile and then work it out. I am willing to put up the hull and electronics and marketing expenses. Believe this to be very sellable idea if I can just get one out on the circuit. Will have someone who would take it out on BASS tour next year if I can get one going.
Kevin

[Kevinkirk]

I cant find the page anymore for that turbine in the outboard configuration. Did they ever get it up and going and is it available for sale? Does anyone know where that might be?
I need a 400 hp turbine for bass boat.

Marine Turbine Technologies.
http://marineturbine.com/marine.asp
Outboard is at bottom of page. I don't know if they are in production yet. I got a quote for a turn key package for a 21 foot boat 350 hp at 30,000 dollars last year.

[jamesbon]

Gas Turbine,
Nice work!

What has your experience been with the Arneson drive? The reason i ask, is I have one in progress of being rigged on my DOnzi Classic with 575 HP 502.

[2 fast]

I woud like to see some footage of that spectacular hole shot they talk about.

[mrcrsr]

i have some ideas but i would like to do it in a sterndrive package(bravo and uo), riverman, that turbine at 317 hp sounded pretty good, i am assuming that it used a power turbine and no reduction gear, so what would the availability of this turbine? i have worked on the allison 501 k17 turbine used in a generator application. any ideas about availability? what about torque output of this engine? any ideas of a 450-650 hp turbine? any info would be greatly appreciated, thanks

[Riverman]

Look here, they sell surplus unairworthy engines.


http://www.avonaero.com/allison.htm

[mrcrsr]

nice website riverman!!! thanx for the info, i emailed to get some idea of pricing

[Riverman]

Reduction gear in the Allison 250 is internal. Output shaft speed is 6000 RPM at 100% N2 (power turbine) RPM, perfect for a boat. At full power N1 RPM is 50,000, N2 is 30,000.

[jmc]

Heres a few pics of the turbine Stroker

[jmc]

A couple of more pics.

[jmc]

One more pic

[klem]

How fast can the stoker run with that set up? Is there a distance other boats need to keep clear?
