Turbine rigging

[KnotRight]

great thread, now I seem to be able to get the drift tango, rik and knot. very interesting machinery and rigging. - jeff

What makes it neat is there are no experts on this.
Ya cant just pick up the phone and call someone.
Most of the rigging shown here could be done several different ways.
I guess what im trying to say is it really is pretty easy to do.
When ya drop it in the water and it does not sink and goes like hell
ya half way there

KR, no kiddin a side NO sinkin, ck.post # 140 a ?

KR, do you have 2-in or are those older photos ? Looks like your area may be hit with 10+ inches of the white cold fluffy powdery stuff between 2-night and into early monday AM. Get her tight to the weather, sure you do ! By the way, in general how often do you need to drain the purge tanks from the combuster chambers ?

Drainage of the tanks is different. I would say 5 to 8 shutdowns.
One bad start just about fills it.


How am I going to work on the tub with this?

You really are a "Fair Weather Sailor" aren't you!

[phragle]

couldnt you rig the catch can to a small electric full pump, set to run momentarily after shutoff?

There are a lot of ways to do this. A sensor could evacuate it or, Gerry could rig a siphon in the can to evacuate it through the exhaust.

McMaster-Carr has some chemical pumps listed that would work.

Not a bad idea.

Whats your thoughts on Venting the oil tank breathers into the exhaust?

Like Drag cars PVC system.

I think MTT does this.


The #3 seal was hanging allowing blow by. Jim replaced it for this season.
It left quite a bit of Oil residue in the engine bay.

That stuff is a ***** to clean and as you have learned by now, it stains everything it touches!

You can vent the breathers, just make certain you have one that will allow air in rather than letting the exhaust suck the tank dry You've obviously seen the old VW diesels and the problems they had when doing this.

So ya have to drain em @ least once or twice a wk-end of hard runnin. do ya think it's time for a re-evaluation of their size or as others have suggested a pump out solution maybe back to an isolated tank and then re-filter back to the fuel tanks. Rik, how U doin - ps: Rik, where on the t-53 is the compressed air port is there more than 1 and what is the approx. output air temp. does it need to be remotely cooled ? -- KR fire em-up that il-melt the fluff. ck. this, maybe overkill, but nice neat stuff; www.X-Change-R.com ck.out the model #922

[tango]

Ok, it is gettin near test and start up time, KR's tanks are full. a few fuel line modifications and the addition of a set of 2-micron filter system heads and them bad boys will be set to FIRE ! ck.this vid. it will get ya in the mood. http://www.vimeo.com/2214228 watch them duke it out.

Strip Poker and I replied on that vid, awesome run!

Knot-Right if I remember correctly, Fusco put that outboard jet motor on so he could 1) dock and undock w/o using the turbines which use as much fuel at idle as at WOT and 2) lessen noise and heat around the docks. I believe it's a 300hp Merc, not sure...

[tango]

Cat, whats up ? your right turbines use alot of fuel @ idle which is about 11k+ rpm, but @ full throttle they use about the same as a couple of over grown BB with blowers @ wide open throttle. then the 2 would be approximately equal and run @ the same GPH consumption rate.

[tango]

hey G, what is the gear reduction of the turbine engine is it between 4:1 or 5:1 do you have the spec. ?

[KnotRight]

N2 (Power Turbine) RPM at 100% is 21,074.

The output After the planetary reduction is 6,600rpm

Divide 21074 from 6600 you get 3.19

Here is picture of my planets.

[tango]

Ok N1 26,500rpm max. (gas Producer) N2 governed to 21,074rpm + - so gear ratio is 3.2:1 gutcha thanks ! ps: planetary gear oil and engine oil in the same sump or separate systems? if the same could they be isolated from each other or is it a single pump design for all rotational mechanisms

[KnotRight]

Yes same oil feed.

In this picture the Rdeuction gears are located right at the very end of
the Turbine. The 22 5/16 studs actualy hold it in. These same studs
is where the Crashbox Bell housing bolts too.

now THAT frickin rocks!!
