The Zeppelin-Lindau Rs.IV (known incorrectly postwar as the Dornier Rs.IV) was a Riesenflugzeug (Giant aircraft) monoplane all metal flying boat with a stressed skin hull developed for the German Navy to perform long range patrols over the North Sea. It had been developed by Claudius Dornier while in the employ of Zeppelin in the town of Lindau.
Development
Two aircraft were ordered by the German Kaiserliche Marine (Kaiser's Navy) in January 1918.[1] The first flight was made on 12 October 1918 and was converted shortly thereafter into a passenger seaplane sometime between October 1918, following damage sustained during its first flight, and June 1919.[1] When it was modified the pilot's position was moved to the hull instead of in the overhead fuselage in 1919. The sole completed example was scrapped on 17 April 1920 on orders from the Inter-Allied Military Control Commission, after a detailed examination of its structural details had been made, while the second example was never completed.[1]
Design
Its design was based on the previous Rs.III, differing primarily in having a narrower hull fitted with sponsons and stressed skin structure, with some minor tidying of the design. It was a braced parasol monoplane with the fuselage mounted on the wing above both engine nacelles and hull. The four engines were mounted in push-pull pairs in nacelles large enough to allow in flight access — a requirement of the original Riesenflugzeug giant aircraft type specification by IdFlieg in 1915 — between the hull and the wing, and staggered to allow propeller disks to overlap slightly so as to reduce adverse yaw when an engine was not running.
It had the distinction of being first seaplane to have an all-metal stressed skin hull, and the first seaplane to be fitted with Dornier's patented sponsons.
