Форум Breguet's Aircraft Challenge

This is the elusive Beese-Boutard Flugboot designed by the German aviatrix Melli Beese and her husband the Frenchman Charles Boutard. Only this drawing / sketch is available for this machine.
   The construction of this flying boat was unique as the hull had a special double construction (twin hull). Each part of the hull had the full capability of floating the entire Flugboot.
   It is said in many articles that the machine was patented, but hours of searching have not returned any Patent of Beese-Boutard's Flugboot unfortunately.
   The machine was powered by a 100 hp Mercedes engine driving a pusher propeller. Length 9,20 meter, Span 15,90 meter, Height 3,48 meter.
   Owing to the boat form no stabilizers were mounted at the end of the wing. The upper wing had a distinct Taube form.
   The machine was definitely built and entered for the Ostsee-Wasserflug-Wettbewerb in Warnem?nde from 1 August 1914 till 10 August 1914, which eventually was called off during the day of 1 August 1914. Twenty-six (26) machines (almost all floatplanes) were entered for this competition, presumably all German (given the patriotic times ...). There were two other flying boats entered, specifically from Rumpler and AEG.
   As said, the famous Hermann Dorner [1882 - 1963 ] helped out with the design of the machine. Beese had already designed a Taube like machine in 1912. I think it will never be known how much Beese - Boutard - Dorner each did with the design, but I think that Dorner had a consulting part in it as he already had his own Dorner Flugzeug GmbH, which folded in 1912. At the end of 1915 Dorner was chief designer of the Riesenflugzeugabteilung of the Deutschen Flugzeug-Werke (DFW) in Leipzig-Lindenthal. From 1916 till the end of WW1 he was chief constructor of engine development (Flugmotorenentwicklung) in the Hannover Waggonfabrik, Abteilung Flugzeugbau, in Hannover-Linden (Hawa). A great career.
   His remaining archive is held in the Deutsches Museum. Possibly it has a shred of information about this Flugboot.
   As said Beese and Boutard were interned as foreign citizens in the beginning of august 1914. According to sources the Flugboot rottet away in Warnemunde, the place where it was built by the Jachtwerft Oertz.
