The Friedrichshafen FF 29 was a German swimmer - reconnaissance aircraft of the First World War . It belonged to the category of the so-called B-types, i.e. the unarmed double-deckers .
development
Due to the positive experience that the Imperial Navy had had with its five FF 19 float planes in service since May 1914 , the naval management placed another order with FF GmbH for eleven units this time. On August 15, 1914, they expanded this by 20 pieces of an improved version that was to be equipped with the more powerful Mercedes D II engine. The designer Theodor Kober only enlarged the wingspan and wing area in the design . The first copy flew for the first time in November 1914 and from December the first FF 29 were handed over to the Navy. In the meantime, the order had been increased to a total of 47 units, seven of which received an Argus engine in a second series and a D II in the subsequent third series. Some aircraft were manufactured under the designation FF 29a at the Kaiserliche Werft in Wilhelmshaven and equipped with weaker DI drives with 105 HP take-off power and a modified tail unit and other floats. The order for three copies was later canceled, so that a total of 44 FF 29 and FF 29a had been built by September 1915. They were deployed from the naval aviation stations located along the North Sea and Baltic Sea or were used as aircraft on ships such as the Answald or the Glyndwr . The successor was the successful FF 33 .
construction
Like its predecessor, the FF 19, the FF 29 was a braced, three-legged biplane with a square hull cross-section and a slightly curved hull top. The floats were flat-bottomed and arranged parallel to one another.
