Type 206

Does the Type 206 have forward dive planes?

Yes it has one of

Yes it has one of the most clever -and strange- forward planes designs. You can see them in your picture. They are called spoons due to the shape they have. They don't pivot. The plane on one side is concave while the plane on the other side is convex. If you want to go bow down you expose the convex plane, if you want to go bows up you expose the other one.

As more and more of the plane is exposed, due to the increasing curvature and area, the higher the angle you can obtain.

This planes desing is a landmark of IKL desings. You can find it from the Typ 201 to the typ 209.

One thing to bear in mind: both planes are never deployed at the same time.

I always wondered if they also had a function in
countering the torque of the large prop.
in that case, they should be both (partially)
extended.

anybody know ?

Thanks

I have since noticed the scribe lines on the hull indicating the shape of the opening for the planes

That's a good question. I know a planesman of a 209. I will ask him but IIRC they always told me they never go out at the same time. I think the torque compensation is done using the stern planes. The bow planes are only usable up to a few knots.

I noticed something in the plans. The flags are pointing forward. When I was in the army i learned that flags on the uniform etc. always should be pointing bakwards like you are going towards the enemy. But on the plan the flags are poining bakwards like you are running from the enemy.
I guess this has to do with old traditions when the warship was wind powered.

Can someone confirm this theory?

Or maybe it was just

Or maybe it was just more expedient to depict the pennant flying forward so it wouldn't interfere with the mast directly behind it in the drawing?

Type 206 bow planes

The drawing shows that both planes are concave which I assume is incorrect. My Engel boat has the lines scribed for the planes , in the correct manner, but because the entire hull is the pressure hull, it would make it difficult to employ the planes operation. I plan on converting the hull so that it will have a WTC.
I have found various Type 206 models on the net and so far I have yet to see one with any deployed planes. I am considering making mine operational. Has anyone actually a Type 206 with this arrangement and did it work very well? I have some ideas on how to do it. I would like to see if anyone else has done it.

Those drawings are from the Revell's 1/144 Typ 206. As you say they show the same curvature for both planes (I never noticed before!) but the actual model is correct. The model is very detailed and I think it is a good reference for a bigger model since there is a lack of good plans of the type. I'm almost sure that the 206 model followed the same design path that the 212 model. HDW gave Revell the real plans (with some censorship) and the model was approved by HDW board later.
