Exhaust details

Xerophobic · Posted: Mon Mar 19, 2007 7:01 pm Post subject:

And of course lastly I did arrange to have one of Howard's engines sent out to use for layout purposes before we committed to the hull design. This engine will run but is not a happy engine. It was run as a testbed for a Canadian military exercise where I believe it was run at 85% throttle for 1000 hrs non stop
The engine weighs 540 lbs and the 11 model I have been searching for makes between 900-1100 HP. A 13B model will make 1400+ but are a little more pricey and harder to find.
Overall I am stoked about the challenges and time will end up being very tight but the worlds only come to your backdoor once every 4 years!

If anyone is interested in sponsorship or knows of companies that may be interested please contact me. Without sponsorship this project will likely not happen in time for this years race.

Cheers

Just awesome.
I read that you are not going that direction but does the offshore gearbox still give CW rotation with the exhaust pointed backwards? What have you got in mind for the intake tract? Something damn tricky I will assume! Will the CG of the boat remain close to a conventional motor setup, looks like it will considering the length. Just wow, amazing, too cool. Wish I lived closer so I could go over and drool on it.
James, you have the coolest toys! (software, playground, resources)

Very cool....I was in there last week and meet/spoke with Xero on this very project.Felt kinda like a schoolgirl with some juicy gossip when I left,but I knew it was only a matter of time before it was announce'd.lol.On the inter-web he doesn't just act,seem or pretend to be a nice guy........he really is Cool

.By the sounds of it he has put countless hours of thought and research into this and it would be a shame for it not to make the Worlds.With that being said,I think that $100.00 dollar ride's would be in order and bring your own crisco or used oil to burn:D .

Xero.....Have you thought of talking to any helicopter company's for sponsorship?Kinda fitting and a good way for them to advertise... Cool

I'm just hoping the engine doesn't resort back to it's old ways and lift off...

P.s.-Below is a pi I took when leaving OE...Big truck on it's side 1 overpass north of the shop Confused

Jesse I spoke with the manufacturer about that gearbox and the cost was staggering. He wouldn't even consider taking on the project for less than 20K Shocked

as if that wasn't enough motivation to forget it right there!

He does make quality units and does alto of work for Mercury racing and delivers something crazy like 150 gear cases to them a year. He didn't much sound like he wanted the work to be honest and not knowing if he'd ever sell one again didn't help.

You can clearly see the disk brake setup on the gear case in that picture. Again this allows the output shaft to be completely stopped while the engine remains idling for docking/slow speed maneuvering purposes. it also will stop the pump for grate clearing without shutting down the turbine. Obviously the turbine takes longer to start/stop than a normal piston engine.

Ive also sourced a different drive shaft setup which is going to be tried by several guys from the looks of it. Not a single engineering/ drive shaft guru type I spoke with said a typical drive shaft yoke setup will be reliable over 3500 rpm. Above that the yokes start to separate due to centrifugal force and that in turn throws the h bar/shaft off balance.
The new system is true CV and is rated to 8000 rpm and 4000 ft/lbs of torque Shocked

Not cheap but may solve the nagging vibration issues a few guys have had in the high HP boats. I don't have pics of that yet but will post when I have a lil more info.

I had thought you must be connected to the mystery turbine boat , but I had no idea that it was going to be your project Exclamation

What a huge step up , so many unknowns . I was thinking the same as A2 on the helicopter sponsor , especially if you could a find engineer interested in helping sort out the vital systems and controls. Good luck and hope you can get it done for the worlds , if throttle response isn't a issue it will most certainly have huge potential . Shocked

XERO,

Aside from the guy back east,do you know of a "engineer"in AB?Reason I'm asking is buddy just went to school for that a couple of years back and never pursued a career in it.Maybe he can help you down the road?This is a guy that went for one ride in my boat and got it in his head that he would own one asap.He got the bank behind him and searched and searched and finally came up with a E6 late last summer.He too has a passion for boats and helicopters so he might be of some use in the tuning stage's...just a thought.

Thanks for the tip where is he located?
I was in engineering myself for 2.5 years and despite never finishing obviously know a ton of guys that did. In fact pretty much all my good friends back in Ont are pro engineers. I have consulted a fair bit with Mark Nye about his project (he initially short listed the T-53 as well) and of course the most valuable person I have onboard is Howard from Firestorm. Can't say enough about his contribution so far and his enthusiasm for the project. I guess part of that is due to the fact he's also going to get a chance to navigate for the race!
He has really made this rather easy in that I do not have to worry about learning turbine101 from scratch. My mind is at ease about getting a surplus engine running and all the details that go with that aspect of the project. Howard also has the connections in the business and I certainly would not hesitate to recommend anyone looking to go this route contact him about his services and engines. He is currently servicing heliski choppers in Revelstoke

Jesse the intake will likely only consist of an intake screen to prevent debris front being sucked into the engine and a pan to prevent the lower intake from sucking water front the bilge area. Contrary to what most believe water in moderate quantities will not harm the engine and in fact I have been told water is often shot into the intake in significant quantities as part of overhauling cleaning procedure. of course it can injest considerably more water at WOT than idle. Part of the other reason I chose this engine layout is i can deck over the rear of the boat all the way forward to the exhaust if needed to prevent rear swamping in the event of a spin

Cheers

p.s. This pic should clarify any questions about shaft rotation. I do not know what rotation offshore guys want but I am pretty sure the gearboxes built all use gears not chains so I assume rotation could be made to whatever you wish.

Xero,
Talk to Westjet, their logo would look good on your boat! A few years back Dowell used turbines to run their frac pumpers, there may be a bone yard around with some parts unless they went back to the US for pasture. Contact Schlumberger, some of the old timers there may have info for you on this. Don't contact Air Canada, their motto is "We're not happy till you're not happy"! And your prices will go up if it is used on any day ending with "Y"!!

With all that air being processed through there, might be a way to have the proverbial totally dry bilge!
Still I say !WOW!

Xerophobic · Posted: Wed Mar 21, 2007 12:55 pm Post subject:

120-130 CFS

yes thats cubic feet per second
Only 1/3 of the air ingested is used for combustion, the rest is used to cool the internal parts of the engine

Cheers

WOW!

That is something else Xero. That is major horsepower there Smile

. Good luck with getting that project done, it would be interesting to see another turbine boat.

A2 the T-53 is still a very common engine in choppers but usually they are the more recent and powerful 13B models.

The reasoning behind the surplus of T-53's is the US military decided to take all of them out of service some years ago. The rule is no military engines may be used for civilian aviation so the engines pretty much sat with no use or value.

Of course that market has changed over the years as both power generation and the marine industry has created a niche and unfortunately driven the prices up! Its interesting to note that a brand new T-53 can be purchased from Kawasaki (I'm sure that's who Howard said had current rights to build them) for 1.8 million dollars! Shocked

Its very rewarding doing the research for this type of thing as you learn so many interesting facts. For example did you know that the intake casting on a T-53 is actually radioactive??? Engineers discovered the alloy was far more durable to the heat cycles of the engine if a mildly radioactive alloy was used so they went ahead and did it. Of course you could stand beside the engine continuously for 35 years and never see any ill effects but its interesting none the less.

By the way to put in perspective the air consumed by the engine: 125 cfs is equal to a cube with 5 foot sides entering the engine every second. Alot of air indeed! It is the sound of this air being sucked into the engine which creates the majority of the sound, not the exhaust itself.

Cheers
