Dornier Metallbauten GmbH / Aktien Gesellschaft für Dornier Fluzeuge / Dornier-Werke GmbH

Dr Claude Dornier

Dr Claude Dornier was employed by Count Zeppelin in 1910, and in 1914 was in charge of the design and construction of large all-metal marine aircraft at Zeppelin-Werke Lindau. Here he produced the Rs.I in 1915, then the largest aircraft in the world, with a span of 43.5m. By 1918 three more giant flying-boats had been built, Rs.II, III, and IV, as well as prototypes of single-seat and two-seat fighters.

All employed Dornier’s techniques of advanced metal construction. After the war the works were transferred to Manzel, near Friedrichshafen, where some two-seaters for the Swiss Air Force were completed. At Manzel, between 1920 and 1925, appeared the Libelle, Delphin, Komet and Merkur, small civil aircraft, and the Falke, an unsuccessful fighter. In 1922 the company became Dornier Metallbauten GmbH and in 1926, as the Manzel works were too small, it transferred to Altenrhein in Switzerland (Aktien Gesellschaft für Dornier Fluzeuge). Here, for the next three years, Aktien Gesellschaft fur Dornier Flugzeug was occupied in building three Do X flying-boats, the largest aircraft of their time, powered by 12 engines. Two were sold to Italy. Bomber designs followed, the Do N, P, and Y being built 1929-1931. These led to the Do F which, like the Do 11, began in 1933 to reequip the German Air Force.
However, in 1932 production was resumed in Germany. The Swiss factory subsequently became the Eidgenossisches Flugzeugwerk.
1932 production in Germany, this time as Dornier-Werke GmbH, began with the military Wal (later the Do 18) and Do 11 bomber, supplanted later by the Do 23. In 1934 appeared its first modern warplane, the Do 17, evolved from a fast, six-passenger mailplane designed for Deutsche Luft Hansa. The Do 17 and its successor, the Do 217, which served as a nightfighter, were the only Dornier designs to see largescale production during 1935-1943. Towards the end of the war the company produced the Do 335 push-pull twin-engined heavy fighter with a top speed of 763km/h, probably the fastest piston-engined Second World War fighter.

After the war Dornier became established in Spain. The first postwar aircraft developed completely in Germany was the twin-engined STOL Do 28. An experimental STOL jet transport followed, the Do 31, and the Do 29 research aircraft. From 1966 the company developed the Skyservant and was involved in international programs. Collaboration with Avions Marcel Dassault-Breguet Aviation on Alpha Jet development and production included research into supercritical wing.
Merkle joined Dornier in 1969.
Became Dornier GmbH in 1972. A majority shareholding was acquired by Daimler-Benz AG in 1985. In 1989 Deutsche Aerospace AG was formed as a corporate unit of Daimler-Benz Group and intended to unite the work of Dornier, MBB, MTU and more, and was renamed Daimler- Benz Aerospace AG. in 1995, with the Regional Aircraft division administered by Dornier Luftfahrt GmbH. In June 1996 Fairchild Aerospace purchased 80% of Dornier Luftfahrt from Daimler-Benz Aerospace, forming Fairchild Dornier Germany Dornier Luftfahrt GmbH. Within Daimler Chrysler Aerospace AG, Dornier Flugzeugwerft GmbH represents part of the Military Aircraft business unit.

Dorner-Begas 1908 Gleiter

A parasol design started by Diplom Ingenieur Hermann Dorner in the spring of 1907 as a glider with a possibility of attaching an engine at a later time. He was financially assisted by Gottfried Begas, the son of the German sculptor Reinhold Begas. The machine was flown by towing it behind a horse and flights made were about 80 meters in distance at a maximum height of 10 meters. Dorner himself flew the machine and as can be seen in the photo, lay horizontally in the same way the Wright brothers would lie on the lower wing of their biplane gliders or early motorized biplanes.

1912 Dorner Company brochure

The Dorner monoplane was a well known sight around Johannistahl. Georg Schendel set a German record for altitude of 2010 meters on 6 June, 1911, and a World Altitude record with passenger, of 1690 meters on 9 June, 1911, in his Dorner. Type II had a 20 hp Dorner-Motor and cost 13,500 Marks. Type III came with a 40 hp Dorner-Motor at 15,500 Marks, or 50 hp at 16,500 Marks. The T.III version had a fatal accident for both passenger and pilot on 9 June, 1911 at Johannistahl.

Dorand Biplan-Laboratoire

A design specially built for the testing of several components, like wings and propellers. The machine was loaded with all sorts of measurement instruments. As this was far before the time of automatic registration, these instruments were photographed in flight. At that time glass plate negatives were used for photographing. Interpretation was made on the ground.

The machine dates from 1910 (although first described in L’Aérophile 1912) and was continuously modified if needed for the tests. Dorand was an old hand in aeronautics as he was already assigned commander of the Établissement Aérostatique at Chalais-Meudon in 1894.

Donnet-Lévêque Type A / Type C

In 1912 four Donnet-Lévêque flying boats type A (no ailerons) and type C (with ailerons) – assigned numbers from 8 to 12 – were obtained by K.u.k. Seeflugwesen. A two-place hulled hydroplane designed by Francois Denhaut, they were powered by a 50 hp Gnome engine.

Aircraft sporting number 10 entered service on January 4, 1913 and was written off in December 1913 due to damage sustained in a crash.

At Argenteuil in 1913, piloted by the marine Konning

On 9 August 1912, Jean Conneau (also known as Beaumont) attempted a Paris-to-London flight. He took off from the Seine, near Bezons, made stops at Quilleboeuf and Le Havre, and the landed at Boulogne-sur-Mer where an accident cancelled the flight.

Jean Conneau’s aircraft was donated to the Musse de L’Air by the Schreck concern.

Jean Conneau’s aircraft

Engine: Gnome, 50 hp
Wingspan: 31.16 ft
Length: 28.86 ft

Donaldson New Graphic

The first attempt at an Atlantic crossing by balloon. Originally intended by John Wise and Washington Donaldson as a 3-envelope aerostat designated the Daily Graphic after the sponsoring newspaper. It was converted to a smaller envelope by Donaldson and renamed New Graphic. Leaving from New York on its trans-Atlantic flight, it reached Connecticut before foundering in 1873.
