1938 - Do 24 V/K - Flying Boat
The Do 24 was a flying boat of all-metal design. The Duralplat-panelled hull with carefully designed aerodynamics carried the typical Dornier sponsons on the both sides. The wing above the hull was supported by a simple strut structure; the three engines with streamlined fairings were installed in the wing leading edge. Do 24 V1 and V2 were powered by Jumo 205 Cs, each rated at 600 HP; the Do 24 was powered by Wright Cyclones each delivering 890 HP. The wing consisted of a rectangular centre section with the engine nacelles and two trapezoid and swept outer wing halves. Continuous split flaps were installed under the wing centre section, and the outer wing halves carried slotted ailerons which could be used as landing flaps.
The horizontal stabilizer with a singlepart elevator was installed directly on the hull tail; the twopart vertical tail unit consisted of outboard fins at the extremities of the horizontal stabilizer. The aircraft had a cockpit with dual controls, a radio/navigation room, crew and sleeping rooms. Fuel was carried in the wing and in the sponsons.
The Do 24 V1 and V2 were built as prototypes. First Flight of the V1 on 10 January 1938. First flight of the Do 24 K, destined for the Netherlands, on 3 July 1937; excellent results in ocean testing in the North Sea in September 1937. The Dutch Navy took delivery of 30 DO 24K, and a further 7 were built under licence by Aviolanda and De Schelde. All operated in Dutch-India (Indonesia).
