The Rumpler 6B1 was a German float fighter aircraft from Rumpler-Werke GmbH .
history
When in 1916 the German Navy demanded stronger protection of its bases and ships against enemy air attacks, numerous companies and Edmund-Rumpler-Flugzeugwerke GmbH submitted a corresponding proposal. In addition to the Albatros W.4 and the Hansa-Brandenburg KDW, the Rumpler 6B was selected.
construction
To save time in the construction work, Rumpler used the C-series reconnaissance aircraft . Their wheel chassis was replaced by two-stage wooden floats , and the observer's seat at the back was covered. The upper and lower wings were in two parts, two-spar fabric-covered wooden constructions with struts made of sectional steel tubing. The wooden fuselage frame was clad in aluminum sheet up to the end of the engine, the sides of the fuselage were made of plywood up to the pilot's seat, the rest was covered with fabric; the tubular steel frame was also covered with fabric. The engine had a radiator under the leading edge of the canopy and a chimney exhaust manifold.
Versions
6B1
The prototype 6B1 was completed in August 1916 and handed over to the Navy under the number 751 after two series machines (787-788) were delivered in July. The other 36 machines delivered by May 1917 and another from January 1918 had smaller horizontal stabilizers with balanced rudders.
6B2
The 6B2, derived from the Rumpler C.IV , with a larger wingspan was manufactured from January 1917 and delivered between October 1917 and January 1918. The originally planned stronger Daimler engine with 260 hp was not installed and so the 6B2 flew with the same engine as the 6B1, which resulted in significant performance losses. The only visible difference was the tailplane, which was rounded at the leading edge.
use
The Rumpler 6B types were in use from the summer of 1916 until the end of the war. Although the machines were less manoeuvrable as a converted two-seater, they were able to successfully prevail against the Russian flying boats over the Black Sea with several kills. The two 6B1 sea fighter planes, which had been stationed at the German naval aviation station Pejnerdjik near Varna on the Black Sea since 1917 , were handed over to the Bulgarian Navy in June 1918. They were destroyed in 1920 by the Allied Control Commission under the terms of the Peace Treaty.
Identification numbers of the Rumpler 6B in the Imperial Navy: 6B1: 751, 787–788, 890–899, 1037–66 6B2: 1188–1207, 1434–1458
