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. Developed by Claudius Dornier while in the employ of Zeppelin in the town of Lindau on the German side of Lake Constance.
Development[edit]
Two aircraft were ordered by the Navy in January 1918.[1] The first flight was made on 12 October 1918 and was converted shortly thereafter into a passenger seaplane between October 1918, following damage sustained during its first flight, and June 1919 [2] At the same time it was modified so pilot was in hull instead of fuselage in 1919. The second example was not completed. It was scrapped 17 April 1920 on orders from Inter-Allied Military Control Commission, after it had been given a detailed examination.[3]
- Riesenflugzeug requirements included access to engines for in-flight repairs
- Development of previous Rs.III, differing primarily in having a narrower hull fitted with sponsons and stressed skin structure, with some minor tidying of the design.
- braced parasol monoplane with all metal internal structure made up of metal girders.
- first seaplane to have an all-metal stressed skin hull, and the first seaplane to be fitted with Dornier's patented sponsons.
- 4 engines mounted in push-pull pairs in nacelles large enough to allow in flight access, between the hull and the wing and staggered to allow propeller disks to overlap slightly so as to reduce yaw when an engine was not running.
- all-metal stressed skin fuselage mounted on top wing above both engine nacelles and hull.
