Came across this 3-view in the July 1944 Air Trails Pictorial magazine, p. 43; there is not additional info provided. Anybody know anything more about it?

Thanks, Bailey -- so, it looks like a graduate paper study produced to obtain an advanced engineering degree. Interesting features.

Hello

Something like the Loch Ness Monster

A B&V patent was published in 1939 , Mr Isacson probably used it for a graduation thesis in Sweden ,the "project " was published in Sweden(and Germany) ,and later in England (Flight 1943).
I believe ,there's a model by UNICRAFT

A year ago on a French forum, I have found this nicely rendered Unicraft B u. V / Isaacson "Zerstoerer". They quite often post there various Luft '46-themed WIPs.

Hi,

Does any-one know which project this is?

The picture comes from a Vami model kit box.

I'm thinking about the Hutter Zerstörer project, but it isn't quite the same.

This is the German Blohm & Voss Zerstörer-Projekt.

I`m afraid that is not a german project. It is swedish. Please see our own thread:

Its not fake, isacson copied the design from a icture he saw of one of blos & voss's projects. The design was a heavy fighter and was named Tungt Jaktplan.

Do you have a proof on that ?,it's really interested if it was not fake.

Whether it's fake or not. Don't contra props rather make the asymmetric offset engine layout less useful? Part of why the BV141's layout works is that it provides a natural counter to the engines torque.

The use of contra-rotating props here is to get twice as much blade area in a limited diameter. To get the same prop blade area in a single prop, the diameter would have to be larger or the number of blades would have to double. You can't get much more diameter without moving the nacelle farther from the fuselage and more than 4 blades wasn't done back then.

But whatever the reason for going with contra props, it seems a silly choice to combine them with an offset asymmetric layout like this. No? Switching the cockpit and front engine over would seem like a much more sensible solution.

Well im just gonna translate the quote. Sigurd started already in the 30's with classic free-flowing models, already winning several contests in autumn 1938, and then acquired an aeronautical education in Norrköping and during the war was known in foreign air press for a "project" "Tungt Jaktplan (heavy fighter)" which certainly was based on any Blohm & Voss patent that he saw and used for a degree project.

So its a real design but what he intended to do with it is unsure, but the blueprints exist and suggests that he did mean it as a real war plane.

Does anyone have the full blueprints which shows the crew and gun placement?
