Design
The Do 12 was a high-wing monoplane, of usual Dornier all-metal construction, with a two-spar, trapezoidal wing, whose trailing edge was very strongly rounded at the root. The fuselage was of rectangular cross-section.
A storage area was in the nose, where equipment, including anchors, could be kept. Behind it, the open cockpit had two side-by-side seats, with optional dual controls. In the cabin, there were two more seats and a storage area, which could also be fitted with bunks for sleeping. Between the cockpit and cabin were nacelles which accommodated the retracted undercarriage wheels, a first for Dornier, which were lowered or raised manually by a crank. The engine sat on a stand high above the wing, alongside two fuel tanks, in pusher configuration.
From the first flight on 23 June 1932, and in the further course of testing, it was obvious that the Argus engine was underpowered, making takeoff distances substantially too long. However, financial difficulties in the company meant that fitting the stronger Gnome-Rhône Titan 5Ke took some time.
Father Paul Schulte, a missionary known as the "Flying Priest", used the Do 12 "D-INEZ" for many years and in his various books it plays an important role.
The Dornier Do 215 was a light bomber, aerial reconnaissance aircraft and later a night fighter, produced by Dornier originally for export, but in the event most served in the Luftwaffe. Like its predecessor, the Dornier Do 17, it inherited the title "The Flying Pencil" because of its slim fuselage. The successor of the Do 215 was the Do 217.
The Dornier Do 335Pfeil (Arrow) is a heavy fighter built by Dornier for Germany during World War II. The Pfeil's performance was predicted to be better than other twin-engine designs due to its unusual push-pull configuration and the lower aerodynamic drag of the in-line alignment of the two engines. It was Nazi Germany's fastest piston-engined aircraft of World War II. The Luftwaffe was desperate to get the design into operational use, but delays in engine deliveries meant that only a handful were delivered before the war ended.
The Aero A.38 was a Czechoslovakian biplane airliner of the 1920s and 1930s. Following the relatively modern A.35, this aircraft was something of a throwback, marrying a fuselage derived from the A.35 to wings copied from the A.23. A few served with CSA, and others with French airline Compagnie Internationale de Navigation Aérienne. These latter aircraft were powered by a French Gnome-Rhône engine instead.
The Dornier Do 212 was a four-seat experimental amphibian flying boat built by the Swiss subsidiary of Dornier, in Altenrhein on Lake Constance. Design was initiated in 1938 by the German and Swiss branches, the latter being responsible for the actual construction of the prototype.
The Junkers W 34 was a German-built, single-engine, passenger and transport aircraft. Developed in the 1920s, it was taken into service in 1926. The passenger version could take a pilot and five passengers.
The Dornier Do 317 was a prototype German medium bomber of World War II.
The Dornier Do 214 was a proposed large long-range flying boat, developed by Dornier in World War II.
Grigorovich M-5 was a successful Russian World War I-era two-bay unequal-span biplane flying boat with a single step hull, designed by Grigorovich. It was the first mass production flying boat built in Russia.
The Albatros Al 101 was a 1930s German trainer aircraft. It was a parasol-wing monoplane of conventional configuration, and seated the pilot and instructor in separate, open cockpits.
The Dornier Delphin was a 1920s German single-engine commercial flying boat built by Dornier Flugzeugwerke. As well as commercial users, single examples were acquired by the United States Navy and the British Royal Navy for evaluation.
The Dornier Libelle, also designated Do A, was a German open-cockpit, all-metal, parasol wing, monoplane flying boat aircraft, with partly fabric-covered wings. There was three versions of the seaplane version; the prototype, first version, and improved version. A landplane version, built without sponsons and fitted with a fixed tailwheel undercarriage was produced as the Dornier Spatz.
The Dornier Do Y was a trimotor German monoplane bomber of the early 1930s designed by Dornier Flugzeugwerke to an order by the Royal Yugoslav Air Force (RYAF). The Yugoslavs originally intended to use war reparations to pay for them, but ultimately had to use their own funds. Only a pair of aircraft were initially ordered to give the Yugoslavs experience with multi-engine bombers and Dornier failed to sell any more Do Y's. Two improved versions were subsequently built on speculation, but failed to find purchasers until the RYAF bought them in 1935.
The SNCAC NC.211 Cormoran was a large four-engined military transport aircraft for passengers and cargo designed and built by SNCAC from 1945.
The Farman NC.470 was a French twin-engined floatplane designed as a crew trainer for the French Navy. It was used in small numbers for both its intended role as a trainer and as a coastal reconnaissance aircraft at the start of World War II.
The Dornier Do E was a small German flying boat of 1924, designed for reconnaissance missions.
The Dornier Do K was a German commercial passenger and freight monoplane, designed by Claude Dornier and built by Dornier Flugzeugwerke. Only three prototypes of different designs were built and the type was not a commercial success.
The Arado Ar 77 was a German twin-engined monoplane, designed as an advanced training aircraft from 1934.
The Blériot 195 was a French monoplane mail-carrier designed and built by Blériot Aéronautique, the one aircraft built was modified a number of times but failed to enter production.
The Albatros L102 / Albatros Al 102, was a German trainer aircraft of the 1930s. It was a parasol-wing landplane, seating the student pilot and instructor in separate, open cockpits. A biplane floatplane version was also built as the Al 102W, with strut-braced lower wings.
The Albatros L 103 / Albatros Al 103 was a German experimental aircraft of the 1930s. It was a parasol-wing landplane of conventional configuration, seating the pilot and flight test observer in separate, open cockpits. The Al 103 was used to test variations in sweepback, dihedral and tailplane area.
