Hi! Kawanishi E13K. http://www.airwar.ru/enc/sww2/e13k.html Auto translation. In 1937, the Imperial Japanese Navy decided to change the old Scout Kawanishi E7K seaplanes (Navy Type 94 Reconnaissance Seaplane) to more advanced aircraft. For this purpose, contracts were signed with companies...

Following the sad passing of the author Manfred Griehl last November, I doubt his pending volume on Fieseler (Fieseler: Flugzeuge seit 1933 - Typenkompass) will ever see publication. This is a great shame as Gerhard Fieseler was a World War I fighter ace who was also a stunt, aerobatic and test...

In a Italian magazine of 1939,"Panorama",i have read an article about Americans flying boats. Was said that a method at the study for land takeoff of flying boats ( in runways near sea aerodromes) was put the flying boat piggy-back on a sort of not flying launch vehicle for reach speed for...

Hi, the French designer,G. R. Hamel was aviator and pilot,and he designed some heavy civil flying boat projects,his activities started from 1935 up to 1945,he created a 100,300,400 & 500 ton Projects. Here is his 100 ton proposal,it was powered by eight engines,in twin fuselage...

Project G - 'Submergible motorboat', originally intended for coastal defence (a 'fighter' concept, armed with two 450 mm torpedoes), prototypes later modified for special operations with the 10th Light Flotilla [Decima Flottiglia MAS]. First batch (prototypes) CA 1 - Scuttled at La Spezia...

My grandfather, Charles Francis Hamel, passed away earlier this year at the age of 93. He enlisted in the U.S. Navy after Pearl Harbor and eventually became an officer and a pilot, flying a U.S. Coast Guard PBY Catalina on North Atlantic patrols in 1945. He got his start in aviation, however...

Alfred Renard built a number of aircraft, mostly before the start of World War II. Alfred started on the ACAZ T-2 but his early substantial design input was at Société Anonyme Belge de Constructions Aéronautiques (S.A.B.C.A.) before joining forces with Stampe and Vertongen. His main work for...

With the recent correspondence on BV designs http://www.secretprojects.co.uk/forum/index.php/topic,6272.15.html I though I would add my notes on the various types. Taken from various sources over years, most recently some old Air Enthusiast magazines and Manfred Griehl's Blohm und Voss...

From "Der Flieger", August 1962, maybe interesting for one or two, as one-offs and projects are mentioned, too.

...so as not to hijack the British thread! Let's start with a subject to which I hope to be able to make a meager contribution to: design constraints and philosophy behind design decisions. Hermione Giffard's PhD thesis and hopefully soon-to-be book "The Development and Production of Turbojet...

Anyone have a three view drawing of the Blackburn B.29 torpedo bomber? prior posting: http://www.secretprojects.co.uk/forum/index.php/topic,4519.msg35771/topicseen.html#msg35771

Does anybody know enything about the competition that led to the USN. I realized that I have nothing but the Boeing Model 374 rival design. Name and details of the request for proposals, contenders? Anything will be welcomed Antonio

As a slide rule addict (and, by way of disclosure, an ordinary member of the Oughtred Society), I'm well aware of the slide rule's proud history in aerospace design and research. Now we know that it almost certainly wasn't all done with slide rules - log and trig tables, mechanical calculators...
