Dornier Rs III
The giant seaplane Rs III was a high-wing monoplane of all-metal design with fabric covering of the wing and empennage. The wing was braced with special cables to the empennage boom and the hull; only its centre part was rigidly connected to the hull by means of steel profiles.
The intrinsically stable hull was a monocoque design made of duraluminium with traverse and longitudinal steps. The hull housed the gun station, the flight deck for two pilots, the engineer's station and the fuel system.
The four Maybach engines were arranged in tandem in two nacelles and installed between the hull and the wing. The radiators were mounted above the engines. The diameter of the two-blade wooden propellers was 3 m. The tail boom was mounted on the wing and had a box-type horizontal tail assembly with split elevator without compensating surfaces; the rudders and tail fins were divided into halves by the fuselage.
First flight took place on 4. November 1917. On 19 February 1918, a 7-hour non stop flight was made from Friedrichshafen to Norderney for further testing by the Seaplane Test Command Warnemönde. The Rs III passed the sea test successfully.
