late 1930s

Starting point Juan de la Cierva had already decided to continue his work motorizing the gyroplane's rotor. He misses his flight at Croydon which crashes in December 1936 because his car has a flat tire. He travels on the next flight, meets with Focke, and together they design and develop two...

Just realized that i have never seen any drawings of interim projects that eventually led to the G-50/F6F. There was an G-33 based on the XF4F-2 but with R-2600 engine, and as i understand initial G-50 projects had still much in common with the F4F (mid-wing, fuselage landing gear etc.). Are...

In UK we know Lion after KGV In USA we know Montana after Iowa In French and German we know Alsace and H class In Japan we know super Yamato and a150 series And how about Italian battleship after Littorio class?

The C-35 and the C-36 are well known, actually built, aircraft of "Eidgenössische Konstruktionswerkstätte" in Thun. The planned C-37 is rather less known. Last year I had the chance to re-work an 1978-article of "Cockpit" and I was lucky to get to see a painting of Roland Eichenberger -...

I've seen a few references to a Supermarine early World War II project called the Type 312. From what I've read, it was a derivative of the Spitfire but with standard cannon armament and a ventral radiator instead of the Spitfire's underwing radiators. Does any photos or plans or other details...

Published in "Техника Молодёжи-Youth Technique" from 1936 the picture shows a fuel supply in flight. The caption to the picture says "The fuel truck (aircraft tanker) flew 30 meters above us and slightly ahead. Suddenly, a hatch opened in the lower part of it, from which a thick hose descended"...

I'm starting a new thread so that it doesn't hijack @airman's Do-19 evolution thread. Is the following feasible, plausible and reasonable? In this timeline the Do 19 and Ju 89 weren't cancelled on 29th April 1937. The Do 19 V3 and Ju 89 V3 prototypes were completed. 12 Do 19A-0 and as Ju 89A-0...

Messerschmitt Me 262 Development & Politics by Dan Sharp There are many myths surrounding the development of the Messerschmitt Me 262 jet fighter. Its unparalleled performance is beyond doubt; easily able to outpace its opponents and possessing the firepower to shred them in seconds. Yet...

In order to avoid clogging the IJN air service thread, I'd open an Army-specific thread for discussion about their alternatives in choice of flying hardware, logistics (as far as they can address it), production, etc. The Pacific war unfolds as it did hisorically, ie. the war with West starts as...

Unknown project of a German ramjet aerial torpedo from 1939.ramjet engine unit ?, total weight 1000 kg, payload 250 kg, speed 300 m/sec, range 300 km, few information about it: Like, project leader, designer or any other technical information. Any further indication would be a good and useful...

A very powerful as it was in the late 1930s/early days of ww2, Luftwaffe was still with some shortcomings. So let's have another go, in making the fictional LW that can put even a better show, especially in 1940. Changes can range from subtle & easy to make (like drop tanks for the Bf 109...

With decades worth of hindsight, what might be the best steps for French AF and industry to make in the 1935 to 1940-41 time frame, in order to put up a better fight against Luftwaffe? Organizational changes, logistics, choice of what to make (whether the historical types, or whatever you think...

Time frame should cover gearing-up to the Pacific war and the war itself. What should've they specified differently for industry to make vs. what was made historically, in order to put up a better fight against the 'West', or mostly against the USN/USMC/USAAF? Not to make a host of designs that...

A bit more conventional was the system of engines in tandem designed during the German occupation by the engineer Michel Vernisse. It was to power the Arsenal VB.10 fighter by using two Hispano-Suiza H.S. 12Z engines. One of them was installed in the nose of the airplane and the other in the...
