This is an alternative history of Goddard's historical liquid rocket launch of 1926 and the succeeding development of a fictional experimental rocket airplane based on Goddard's designs. The advent of the design and its governmental support ultimately leads to a change in the course of the US...

The Ohama and her sister ship Okashi were laid down as target ships, successors to the Hakachi. Ohama was completed as an escort vessel, and Ohashi collided with Yamashio Maru and sunk before completion, but would have been given the same treatment. I can't find any illustrations of their...

Video might be of interest. Can't speak to its accuracy, but at least it doesn't seem too insane. View: https://www.youtube.com/watch?v=kfio0VHXUmw

Hai Except some drawings concerning the P-33 projects, I did not find any information concerning other Brewster projects. The only which I earlier mentioned was the two-seat fighter, further no details etc. Is there any material/information concerning this two-seat fighter and other not...

Freshly published:

Or, in other words, lets give to the FAA some attractive hardware that gets the job done and then some. Whether something later to be made earlier, or something that never flew, or a substantial mod to an existing design. Limitations of availability of engines, armament and electronics remain -...

This thread is organized by ship type when information is available, and includes general plans when unavailable. It starts with Destroyer plans, moves to Battleship plans, then to Cruiser plans, and finally to Aircraft Carrier plans, followed by lists of various war demands and fleet building...

Since the end of the First World War, bold attempts were made in the Soviet Union in the field of rockets and various types of weapons, although timid, but existing and somewhat significant for the hard period that the Union was going through at that time, sometimes typically handcrafted and...

In the magazine "Décollage" N°64 of 06.19.1947- p 12 .a reader Mr. Alphonse Martin informed the editorial staff of the magazine that he realized in 1939 the plans of a self-guided bomb. It is a gliding bomb launched by plane and equipped with an automatic piloting device which directs it towards...

You may read some info from Maiwaffentrager's blog or somewhere else, which I seriously doubt any credibility. I would assume that these names show some certain design features, rather than factory names, I'll explain now. What Maiwftrgr. said Ai-96, Mitsu-97, Mitsu-104, Ishi-108, have names to...

I found an interesting chart comparing fuel efficiencies of actual aircraft. Please compare the Ju 86 with petrol and diesel engines. The difference is massive! The source is Shell Aviation News April 1939. Article by some Lufthansa director.

Hello and welcome, This is a hub for all things Kriegsmarine. You will find information, data, and even deductions like this nearly nowhere else - and I take great pride in that. So if you have a question about the Kriegsmarine, are looking for some specific ship or weapon, or even want...

For these cruisers I got most of my data from Norman Friedman's British Cruisers Two World War and After as well as from the forum member Smurf and parts from his book: A Directory of British Cruiser Designs. In case of Friedman's book it wasn't always clear what data was connected to what...

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...

Grigorii Ivanovich Bakshayev was interested in the concept of variable geometry aircraft, where the size and/or shape of wings are altered according to the stage of flight, or desired characteristics. There are many methods of achieving this but one of the simplest is the telescopic wing, where...

A big Surprise, here is a drawing and all Info about Bellanca C-24-100-P and C-24-100-M,generally it was a single or two-seat fighter,observation,light bomber and attack airplane Project,developed from Model 28-90. I don't know for which competition it was purposed,and if it was estimated to...

Hello there! I've been trying to find data on French aircraft carrier designs between the Joffre and the Clemenceau (PA-54). I've found plenty of data on the PA-28, but I'm very interested in the supposed PA-25 design from Vichy France and the PA-27, PA-29, PA-31 designs from 1945 onwards...
