Keep up the great work and the excellent photos of each stage of the rebuild  ;)

: Re: Tugboyben's Smit Nederland
: sea.mariner February 03, 2010, 12:20:12
Thats a good idea regarding your korts but if you are using just a straight piece of pipe, you might find you will loose some thrust ?

Those Becker rudders look great  :)

Regards, Dan.
: Re: Tugboyben's Smit Nederland
: sea.mariner February 03, 2010, 12:27:01
A better photo here showing how the shape of a Kort allows water in (from the direction of the camera) then creates more thrust exiting the smaller diameter 'outlet'.

I am sure you are aware of this but some members might not be so this is why I am showing the photos  ;)

Forgot to say in the last post, you are making really great progress  :) You obviously have a warm workshop to be modelling in the current UK weather !!

Regards, Dan.
: Re: Tugboyben's Smit Nederland
: tugboyben February 03, 2010, 12:54:14
hi dan

cheers for that i will have a look at that tomorrow may put some plastic card on the inside of the korts i will get back to you

yes the work shop is warm i when out three weeks ago & got a gas heater 8)

jason
: Re: Tugboyben's Smit Nederland
: sea.mariner February 03, 2010, 13:07:27
Maybe a coating of car body filler from Halfords, applied evenly about 5mm thick, then once it is set, using sandpaper, sand it down to shape ? This would only be easy if the korts are not fitted, its much easier to do this by holding the kort in one hand and sandpaper in the other  ;)

Again just a suggestion but I think plastic-card may not be the soloution  :)

Regards, Dan.
: Re: Tugboyben's Smit Nederland
: chipchase February 04, 2010, 01:01:38
Coming along great Jason, I like those decaperms I was thinking about a pair of these for my new build but I donít think they will have the power that I will need. (Possibly two car fan blower motors like the ones in the link you put on).   You could put a small section of plastic drainpipe on the inside of your nozzle and shape the ends with car filler; you would have to shape your props as I donít think you have a lot of room.


Brian
: Re: Tugboyben's Smit Nederland
: Model Tug Man February 04, 2010, 07:03:58
Don't sweat it too much Jason. While the airfoil cross section increases intake, like Dan mentioned, the nozzle also acts like a fan shroud and directs the prop flow directly astern with none being lost laterally. Back in the day--early 80s--I had a 45" Shelly Foss hull and made korts out of 4" PVC pipe. There was considerable difference with the nozzles installed and they had not been shaped much. You are doing a great job and I am sure your tug will perform well which ever way you end up going. Keep those posts coming. :) :) ;)

 8) 8) 8) 8) 8) 8)

       Hi Jason
                     By having a circular aerofoil section the prop creates a positive pressure at the inside narrow end of the kort
   and a negative pressure on the outside rear of the kort , the resultant pressure  difference causes a lateral force to be
   applied to the kort which in turn is transmitted to the hull through the kort pintle on steerable or through the kort fixings
   on non steerable korts. This aerofoil section is quite different to an aeroplane section where an upwards force is generated.

                     Full size korts increase the thrust on the ships hull up to 30% at very low ship speed and above 12 to 15 knots the kort
   nozzle drag negates  the extra thrust, so korts are mostly used on tugs, trawlers, etc.When kort  props go astern they have
   a distinct dis-advantage of generating an opposite and negative thrust, and that`s why korts that can turn through 360 degrees have props
   that only go ahead for max thrust on ASD tractor tugs

                     Hope it makes sense,and yes I would use an aerofoil section.

                                      regards      pompy boy

Looking better Jason  :) What did you use for the 'filler'' and I could recommend a 4 blade propellor which will be more efficient and gives more thrust.

Regards, Dan.

ps, obviously for the maximum thrust possible from a kort nozzle, you would need kort props, depending on the diameter you are left with within you kort nozzle you may need to order props or if you are lucky you could find some to fit perfect  :)
: Re: Tugboyben's Smit Nederland
: tugboyben February 05, 2010, 13:24:39
hi dan

my plan is to get a pair 4 blade kort props i will get some 50mm props in the korts as the copper pipe is 55mm (dia) if some one as some for sale they need to fit a M4 shaft the filler is car body filler with a strip of 5mm by 10mm plastic card

thanks jason

I am sure you are aware of the range of Kort props sold by the PROP SHOP ;

Also cornwall model boats ;

Looking good Jason, exhalent work on your nozzles. I bought two 70mm 4 blade kort props from prop-shop, not cheap at £60 but exhalent quality (you only get what you pay for)

How's this build coming Jason?? ??? ???

John:
If you're building a Carousel tug; I assume you'll be doing away with the original housework?

Is this a 'Billings' kit?

Here's an idea....why not install a Schottel drive up forward; perhaps a Graupner unit?
Keeping the twin 'Becker' rudder set up aft...she'd be quite the maneuverable unit :) :)

Just an idea.

I no longer have the smit i got it ready to paint & offered a good price so i sold it that way help me fund two new builds a few pictures
