A tiltrotor is an aircraft that generates lift and propulsion by way of one or more powered rotors mounted on rotating shafts or nacelles usually at the ends of a fixed wing. Almost all tiltrotors use a transverse rotor design, with a few exceptions that use other multirotor layouts.
The Göppingen Gö 9 was a German experimental aircraft built to investigate the practicalities of powering a plane using a pusher propeller located far from the engine and turned by a long driveshaft.
The Dornier Do 12 Libelle III was the third of a line of small German flying boats of the 1930s. It started with the Dornier A Libelle I and the Dornier A Libelle II, though the Do 12 was not a continuation, but an entirely new aircraft.
The Flettner 184 was a German night reconnaissance and anti-submarine autogyro developed during the 1930s.
The Arado Ar 67 was the single-seat biplane fighter successor to the Ar 65.
A backpack helicopter is a helicopter motor and rotor and controls assembly that can be strapped to a person's back, so they can walk about on the ground wearing it, and can use it to fly. It uses a harness like a parachute harness and should have a strap between the legs. Some designs may use a ducted fan design to increase upward thrust. Several inventors have tried to make backpack helicopters, with mixed results.
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway.
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.
The Focke-Wulf Fw 56 Stösser was a single-engine, parasol monoplane advanced trainer, built in the 1930s in Germany.
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.
After the success of the 1940 airborne assaults involving the DFS 230, the Reichsluftfahrtministerium invited the Deutsche Forschungsanstalt für Segelflug/DFS and Gotha to submit plans for a larger capacity glider. The result was the DFS 231, a twenty-seat troop designed by Hans Jacobs, who had previously produced the successful, nine seat DFS 230.
The Flettner Fl 265 was an experimental helicopter designed by Anton Flettner.
The Flettner Fl 185 was an experimental German gyrodyne developed by Anton Flettner, a machine which could fly both as a helicopter and as a gyroplane.
The Bücker Bü 134 was a German single engine, high wing cabin monoplane prototype designed and built by Bücker Flugzeugbau GmbH.
The Baumgärtl Heliofly III/57 and Baumgärtl Heliofly III/59 were 1940s experimental backpack helicopters designed and built by the Austrian-designer Paul Baumgärtl. Following on from his earlier experiments with strap-on autogyros the Heliofly III/57 was powered by two 8 hp (6 kW) Argus As 8 piston engines each driving a single-blade of the contra-rotating rotors.
The Arado Ar 77 was a German twin-engined monoplane, designed as an advanced training aircraft from 1934.
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.
The Hamburger Flugzeugbau Ha 135 was the first aircraft produced by the new aircraft subsidiary of the German company Blohm & Voss.
