interwar period

Hello, I'm looking for warships designed by Nevesbu (B.V. Nederlandse Verenigde Scheepsbouw Bureaus). Specifically for surface vessels, though I don't want to discourage discussion around their submersibles. So far I'm aware of a couple of designs: Project 1047 (files attached, source: Klaas...

Does anyone know anything more about this? https://collections.rmg.co.uk/collections/objects/568598.html Description Scale 1:192. A plan showing the outboard profile and arrangement of rig of a proposed aircraft carrier/liner hybrid by Eustace H. T. D'Eyncourt [Director of Naval...

If the drawings below are accurate, the resemblance is a bit odd, and profuse apologies if the topic was discussed before. https://www.the-blueprints.com/blueprints/ww2planes/messerschmitt/78737/view/messerschmitt_bf_109x_v21/...

In the very first years of aircraft carriers development both English and Japanese envisioned launch of their aircrafts directly from the hangar. This result was usually achieved through an opening in the bow, at the hangar level, and a catapult that launched aircraft in the ship's direction...

So, Austrians had Italian fighters Fiat CR.32 but why they didn't decide to develop their own fighters? Here's the pic of an Austrian CR. 32

Anyone solve the mystery?? Why, oh why did the JUNKERS G.38 4-engined prototype test-fly with a four-bladed propeller, inboard and a two-bladed propeller, outboard on each wing? All four driving engines were identical. Might this have caused any power imbalance/handling or thrust deficit issues...

Hi! I will post these aircraft.

There is already a thread on what might have been in the 1930s. I want to focus on the land forces. Britain and France in 1940 had some tanks (Somua and Matilda 2) which could match the Germans. If the French and British General Staffs had understood the importance of armoured units in a...

Inspired by the “What if the gas turbine hadn’t happened“ I always thought of a different angle. This considers what would have happened if just two men had a different mindset at just one meeting? Ref “Genesis of the Jet” John Golley. This book documents Frank Whittle struggle to develop the...

What if the United States Army Air Corps was limited to Ford Tri-Motor transports until the onset of World War 2? For the purposes of debate, Bill Stout is allowed to update the basic Ford airframe to 23,000 pound gross weight and up to 725 horsepower per engine, but is still limited to the...

Good listings of Soviet naval project numbers are difficult to find. Some were published in books following the events of 1991 and of course Globalsecurity published a list in the late 1990s. No details at all were released of merchant vessels, so about two years I set out to complete a list and...

The British Air Ministry created a designation system for the installations of radio equipment in the late 1930s, each number reflected the standardised installation of a particular radio transmitter or receiver and all the various elements including power units, aerial connections, and control...

From British Civil Aircraft since 1919, Mr. F. W. Broughton built a single seat parasol wing light monoplane,powered by one 30 hp Carden,developed from Perman Parasol,called Broughton-Blayney Brawney.

Note: I know there already exists a thread about SAAB designations etc but that thread also includes other companies besides SAAB. Link to thread. While i understand why those companies were included i personally think we should have a thread dedicated to each of them separately as they designed...

Hi, Mr. Adolphe Lachassagne began in 1912/13 to built a tandem wing airplane,called AL-1,and described as "automatically stable",followed by a AL-2 in same concept,the AL-3,AL-5 & AL-6 were a single seat low-wing ultra-light monoplanes,but with different engine,AL-7 was a tandem wing in new...

The ADC Cirrus was the first reliable and affordable aero engine and together with the de Havilland Moth, in the mid-1920s it created the golden age of private flying. It was also the first of the mass-produced small air-cooled four-cylinder inline light aircraft engines. And it has a curious...
