TURBINES IN A BOAT!

Hello to all my Skater brothers!

After all the hard work I put myself through.
I realize that most of you must think that I should seek counceling.

Well I am! 12 ounces at a time:ernaehrung004:

Heres the plan.

Remove two good running PSI Blown chevys.
INSTALL TWO MARINIZED LYCOMBING T53,s L13B,s TURBINES in a 46 SKATER.
PROJECTED TOP SPEED 180MPH+



I took one final picture of the piston engine installation.

The removal takes place today!

Lets have some fun!:cool-smiley-026:

You always have the most interesting projects!
Ed

Everything disconected and ready.

Gotta love how easy it is to work on these cats.


Just waiting for a xtra set of hands.

met u @ Fall River poker run
 

Gerry/or/Jerry (1st 1 I believe). Anyways I was on Paul's 33-Sutphen "Outrageous" @ F.R. (the orange boat next to u-guys). Thanks for all the pics from yourself and Art. "Airtime" I think u-are correct a 30 pack may not even cure your endless desire to drive yourself beyond reasonable decision making :cool-smiley-011: best of luck jay "1CE"

Ed, your not that far away. The next time your heading this way stop by!

Theres plenty of fridge in the beer.

Whaz up???

The next poker run I gotta bring more beer Atleast two coolers
after the run Pete Nopper pretty much cleaned me out.:D

Say hi to Paul for me!
Why dont you guys stop by also I have the video here.
Not the best video however there is some decent footage of
outrageous.

Here is a picture of the Caliper controller.
This is activated by a micro switch in the shift which sends voltage to the coil and the onboard air system will apply air to the cylinder which mechanicaly pushes the master cylinder which squeezes the caliper stoping the N2 on the turbine enabling a shift in and out of forward neutral reverse.

Hello Gerry
Thanks for the invitation! Too bad I wasn't close by today, I could operate the backhoe.
Ed

Motors out!

Knot-Right, the name couldn't fit any better!!!! Great thread, I liked the first build, I think the next build thread will be even better. Good luck on the conversion, if I was closer I'd help ya with the beer, and the project.

In the end, you will be far better off doing this than you could imagine.

It just takes one major concern off your mind when boating.

Just wondering how are you going to control the N2 speed when the boat leaves the water? I am not sure if the standard setup on the T53 works quick enough.

I decided to use the mechanical governor and a frequency counter on the N2 shaft to operate the brake if the N2 went over a set speed, and an over-temp system to aid startup.
A Kevlar blanket is good insurance as a backup!! incase of any failure.

Hey, at least turbines don't leave belt dust everywhere! :D

Did you use the tach generator on n2 for the input
to the freq counter?

Sounds like a good idea.
Thank You!

The dust was actualy getting into the cabin via the 3 inch pvc
Skater uses for wire troughs.:hitfan:

The engine I used had a pick up on the free power turbine shaft before any reduction took place in the gearbox. You should be able to use the n2 tacho output.

Yessss! This is going to be a good thread!:party-smiley-048:

My Turbine builder seemed interested in your idea.
Another thought would be to ride the govenor.
For explanation sake you would lets say have two throttles one would add the fuel and the other would set the govenor
limit.

So you throttle the fuel then you just take the govenor and limit the Rpm via the govenor.
Boat leaves the water it is already on the govenor.


Here is a schmematic of the fuel system taking from the
T53 Work book.

All of the above could be applied mechanical
Via shift cables/Perhaps fabricate a multi stage shift lever
so when applied the throttle would come in and then later
in the mechanical throw the second (Govenor) would
come in and limit the amount of Rpm.

Now that I spewed all that BS Im gonna go watch Mcgiver:D

all that B.S. Mcgiver
 

GERRY U-can't fool us and bet your reading every blue print u-can find right now, even if knot u-will make it "right". Anyways if you want Paul and I would love to stop by and lend 2-sets of hands. :circle: J 1CE---for the beer ? & learning curve too !

I cant read!

Paul knows how to get here.

Let me know when your coming so I can run out and get enough refreshments to satisfy you animals.:D

Ok this just in.


I made the mistake of telling the turbine builder that
the PSI,s had more bling.

Well enough said.

Whos your daddy now Beotch????

These are my actual turbines going together.

Stainless steel compressor housings.

The original t53s I beleave had magneasium.
Which salt water loves.

One of the features which was built into the original
rigging was a sound elimination device. This was used
around the dock so you dont have to scream at your wife
or girlfriend to grab the freakin dock line.

Stay tuned for the details.

Sounds feasible to use the T53 Variable governor to alter the maximum load. I would still use a pulse counter to activate a relay closing the fuel solenoid + brake in case of any shaft or gear failures this will stop the N2 over-speeding wile under full load.
Then use a temp control system to close the same fuel solenoid if the engine over-temps at any point this means you don't need to watch the EGT all the time, as any over-temps that take place will shut the engine down automatically before any blades are damaged.
These units are widely used in commercial temperature control and have more than one alarm set point that can trigger relays/lights ect.

I gather you don't what to cover those nice shiny hot sections with a containment blanket!
Ever wondered why the hydroplanes have blankets on there hot sections?

Maybe you should have a look at this

http://www.youtube.com/watch?v=5F-I0...elated&search=


I know it a bigger motor but there is still a huge amount of energy in those T53 N2 turbines at 100%+

T53 Containment test
http://www.tc.faa.gov/its/worldpac/techrpt/ar98-22.pdf

Go down to the pics at the bottom.

A little Kevlar is worth its weight in gold

Normal operating range for a T-53 is between 900 and 1150 degrees F. Normal cruise operating( TIT, turbo inlet temperature) temperature range at altitude for a turbo piston plane is 1650 degrees F. My plane has not melted down yet and has no blanket.

Never had a hot section problem in any motor other than the PT6 and those will scatter and when they do it puts holes everywhere.

Yep I agree they are generally very reliable, but for the price of containment blankets its cheap insurance to have. If one does let go be prepared to loose your boat and anyone around it!
Don't get me wrong I am not against turbines but you need the right safety measures in place when using them in boats otherwise the unlimited hydroplane and tractor pulling teams wouldn't use containment would they?

Airliner engines are supposed to stay together also but here's one that didn't.

Let's put the racers in perspective.

Both the unlimited and the tractor pull guys are over speeding the turbines. Way different scenario than that of the pleasure boater or 99.9% of turbine users.

Blankets are cheap, use them but be realistic about why things happen and don't be fooled into something for the wrong reasons.

Gerry, Boy have u-got them all going ! Thought you just wanted a couple of new popcorn makers. But as you know if the foil gets torn you have one helllllll of a mess and all that iced down beer will not kool it off ! Will talk to Paul about shooting down sometime as always best wishes J 1CE:food-smiley-007:Be safe I know u-will.

Menace. Which 46 Skater is yours?

HOLY SHT!!!!

This is going in your boat! AWESOME!!!!!

When are you going to have it on the water?

Wraping it with some kevlar would be cheap insurance.



Ok how about wiring.....Pictured below is a voltage regulator for the 24 volt anyone care to comment on how this is wired?

The rest is pretty straight forward.
The picture with the three contactors The middle is the reverse current relay the two outsides are 600 amp
start contactors.
I will have a switch to throw to engage the 24 volt charge
wired to the reverse current.
The start relays are easy they can go right to the crank
Key ignition.
Some other features we will employ will be a seperate switch
for the start fuel. This willl help in the event of a hot start
if the pyro is climbing to high on startup you will have the ability to cut the x-tra start up fuel. This should reduce the
pyrometer temp.

Shooting for January 08.
There should be snow on the ground here by then.

Gerry, change your avatar That one is history already.

Wait until you start those puppies up the first time on a hose. You will be looking for some open water to splash that thing in January.

This is a cool post keep it going

Here are some shots of the inlet housings and compressor.



These are Stainless Steel housings.:cool-smiley-027:

Some pre machining was required. They will be sent out for metal spraying then remachined to tollerance.

This just in from our Cad design center.


Its basicaly what came to me while at a bar written on a
cocktail napkin with a crayon.


Anyone care to modify it?

It is the water setup for the engines.
I have got dry exhaust and the only water it basicly
needs is oil cooler and maybe power steering.

Im thinking this pump.http://www.jabsco.com/products/marin...2098/index.htm

Why not use a heat exchanger and make it a closed system ?

That way you can control the oil temp. and not worry about the salt water. Not sure on turbine how important that is.

CM

My thoughts at first was the same However,
The canton oil stats I used for the Pistons
run at 215 this is close to the Recomended Turbine
oil Temp.

This in combo of what I illistrated should work.
