The Ship Model Forum

Oh, and BTW: still completed :cool_2:

Thanks!

These are the coverings of the companionways. They are not clearly to be seen on the photos (maybe they were added after the first sea-trials) but the half-model in the Museé de Marine in Paris has them also.

Egberth I am curious... What are those?

Well, it behaves like a drunken sailor: Very maneuverable but unable to steer in a straight line.

What a great looking model Egberth :thumbs_up_1: But, like Dave, I am curious about how does it behaves itself on the water?

Thank you Dave,

It was not seamanship more luck and knowing the quirks of handling a frisbee!!
She tends to crab about a bit rather than running a straight and true course.

The model in this thread is far better than my attempt, I was hindered by pre internet and accurate drawings for my model. which was started in 1988, and only completed to a half decent standard in 2007.
Since then i have managed to gather a lot of decent quality info on Novgorod from a friend in Russia,

I love the finished Kiev model by the way!

I remember 3 years back seeing a build of the Novgorod competing in the UKs national STEERING championships for scale ships. It was almost impossible to see how he could steer this vessel in a straight line let alone turn the vessel in any desired direction but he did and gained a first placing just an amazing bit of helmsmanship.

Hello!
Me the information on the ship Vice-Admiral Popov interests.
Who can help?

Great build, I've always been fascinated with the round ships. Wish I had those molds!

One of your props seems to be cavitating big deal.

Cavitation can be seen because of the bubbles behind the prop.

Not really. It's just because the props are only a few milimeters
underneath the water surface. As you can see in the pictures the ship is
propelled with two bell-shaped rotor motors. These are usually
slow-runners. With those it is absolutly impossible to get an
cavation-effect (unless of course the prop get's partially out of the
water - which may happen depending on waves - but that would result in
hyper-cavitation). Cavitation can appear at the propellers of RC racing-boats, where it lowers the speed of the boat. On the other hand hyper-cavitation is sometimes an appreciated effect (created by hydro-props that are only half-immersed) because it reduces the friction of the propeller.

That could destroy it in not all too much time.

Lord, no! That's a model-making-legend. Cavitation may cause destructive problems
with real-size propellers but not with the propellers of our little
ships. The bubbles and as a result the implosion-jet are just too small
to have any effect on the propeller's surface. It may cause a decrease
of effectiveness of propulsion but as far as propulsion ist concerned
cavatation is the most minor problem concerning a round ship without an
effective rudder.

It looks pretty good indeed!!

Cavitation can be seen because of the bubbles behind the prop.
Cavitation is water starting to boil because of low pressure at the suction side of the prop.
As soon as the pressure rises again at the other side of the prop the bubbles caused by the boiling water implode releasing quite a lot of pressure, which can damage the prop and anything else in the area.
I don't know how you can solve this problem, having it turn slower does help.
If you want to be able to maintain topspeed you'll need to try adjusting the blades carefully and test when the bubbles are gone.

I''ve always been intrigued by this ship. Thanks for pulling it out into three dimensions! A fine, fine build :thumbs_up_1: :thumbs_up_1: :thumbs_up_1:

This is also the first time I've heard of resin soaking paper for hard-to-reproduce items. Could you describe how you did that - what kind of resin, paper, etc? I'm itching to try that!

Thanks for the education :big_grin:

And last but not least a video of the ship on the water:
