Focke-Achgelis Aircraft
Focke-Achgelis & Co. G.m.b.H. was a German helicopter company founded in 1937 by Henrich Focke and Gerd Achgelis. History Henrich Focke was ousted in 1936 from the Focke-Wulf company, which he had cofounded in 1924, due to shareholder pressure. There is reason to believe that Focke's removal was to allow Focke-Wulf's manufacturing capacity to be used to produce Bf 109 aircraft. The company was taken over by AEG, but soon after this the Air Ministry, which had been impressed by the Focke-Wulf Fw 61 helicopter, suggested that Focke establish a new company dedicated to helicopter development, and issued him with a requirement for an improved design, capable of carrying a payload. Focke established the Focke-Achgelis company at Hoykenkamp, Germany, on 27 April 1937, in partnership with pilot Gerd Achgelis, and began development work at Delmenhorst in 1938.

VTOL
A vertical take-off and landing (VTOL) aircraft is one that can take off and land vertically without relying on a runway. This classification can include a variety of types of aircraft including helicopters as well as thrust-vectoring fixed-wing aircraft and other hybrid aircraft with powered rotors such as cyclogyros/cyclocopters and gyrodynes. Some VTOL aircraft can operate in other modes as well, such as CTOL (conventional take-off & landing), STOL (short take-off & landing), or STOVL (short take-off & vertical landing). Others, such as some helicopters, can only operate as VTOL, due to the aircraft lacking landing gear that can handle taxiing. VTOL is a subset of V/STOL (vertical or short take-off & landing). Some lighter-than-air aircraft also qualify as VTOL aircraft, as they can hover, takeoff and land with vertical approach/departure profiles. Electric vertical takeoff and landing aircraft, or eVTOLs, are being developed along with more autonomous flight control tech ...

Helicopter Manufacturers Of Germany
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 STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most common hel ...

List Of RLM Aircraft Designations
This is a list of aircraft type numbers allocated by an institution under the direction of ''Heereswaffenamt'' (before May 1933) and the Reich Air Ministry (RLM) between 1933 and 1945 for German military and civilian aircraft and in parallel to the list of German aircraft engines. See RLM aircraft designation system for an explanation of how these numbers were used. There is no single "master list" applicable all the way from 1933 to 1945 - numbers were occasionally duplicated, reallocated, or re-used. Sources differ on the allocations.

Rotor Kite
A rotor kite or gyrokite is an unpowered, rotary-wing aircraft. Like an autogyro or helicopter, it relies on lift created by one or more sets of rotors in order to fly. Unlike a helicopter, gyrokites and rotor kites do not have an engine powering their rotors, but while an autogyro has an engine providing forward thrust that keeps the rotor turning, a rotor kite has no engine at all, and relies on either being carried aloft and dropped from another aircraft, or by being towed into the air behind a car or boat or by use of ambient winds for the kiting. As of 2009, no country in the world requires a license to pilot such a craft. History * Thomas Ansboro of Glasgow, Scotland patented an autorotating-winged rotor kite in 1891. * Walter Van Wie filed a patent for a ''Revolving Kite'' in 1909 claiming "certain new and useful Improvements" in revolving kites" * 1933: Filed: July 11, 1933US2074327by De Courcy and Schwarz for ''Kite''. * 1936: Filed: Aug 1, 1936US2181477by Carl B. ...

Focke-Achgelis Fa 330
The Focke-Achgelis Fa 330 ''Bachstelze'' ( en, Wagtail) was a type of rotary-wing kite, known as a rotor kite. They were towed behind German U-boats during World War II to allow a lookout to see further. Development Because of their low profile in the water, submarines could not see more than a few miles over the ocean. To solve this, the German admiralty considered a number of different options, including a folding seaplane (Arado Ar 231). In the end, they chose the Fa 330, a simple, single-seat autogyro kite with a three-bladed rotor. The Fa 330 could be deployed to the deck of the submarine by two people and was tethered to the U-boat by a 150 m (500 ft) cable. The airflow on the rotors as the boat motored along on the surface would spin them up. The kite would then be deployed behind the U-boat with its observer-pilot aboard, raising him approximately 120 meters above the surface and allowing him to see much farther — about 25 nautical miles (46 km) ...

Multicopter
A multirotor or multicopter is a rotorcraft with more than two lift-generating rotors. An advantage of multirotor aircraft is the simpler rotor mechanics required for flight control. Unlike single- and double-rotor helicopters which use complex variable pitch rotors whose pitch varies as the blade rotates for flight stability and control, multirotors often use fixed- pitch blades; control of vehicle motion is achieved by varying the relative speed of each rotor to change the thrust and torque produced by each. Due to their ease of both construction and control, multirotor aircraft are frequently used in radio control aircraft and unmanned aerial vehicle (UAV) (drone) projects in which the names tricopter, quadcopter, hexacopter and octocopter are frequently used to refer to 3-, 4-, 6- and 8-rotor rotorcraft, respectively. There is also the X8 (also called ''octo-quad'') configuration that is similar to the quadracopter design, except that it has eight rotors; the lower of whic ...

Focke-Achgelis Fa 325
The Focke-Achgelis Fa 325 ''Krabbe'' was a proposed rotary wing transport designed in Nazi Germany by Focke-Achgelis in 1942. Design and development Heinrich Focke began designing the Fa 325 for the Kriegsmarine, which was interested in a torpedo-armed helicopter. The design had four rotors, and was, effectively, two Focke-Achgelis Fa 223 Draches attached to each other, powered by two Bramo 301R-3 radial engines (BMW development of the Bramo 323 Fafnir engine for helicopter use). Empty weight was calculated at , and maximum take-off weight at . The Kriegsmarine leadership withdrew from the Fa 325 project in 1943, and Focke ceased further development.

Focke-Achgelis Fa 284
The Focke-Achgelis Fa 284 was a project to develop a large transport helicopter, designed in 1943 by Focke-Achgelis for use by the Luftwaffe. The helicopter was powered by two BMW 801 radial engines, driving transversely-mounted rotors, and was equipped with a large, detachable cargo pod for carrying loads.Lepage 2009, p.382. The Fa 284 project was abandoned in late 1943, being replaced by a design for an enlarged version of the Fa 223 featuring a four-rotor arrangement; this project was also abandoned.Kay and Smith 2002, p.293.

Focke-Achgelis Fa 269
The Focke-Achgelis Fa 269 was a tiltrotor VTOL aircraft project designed by Henrich Focke. Development Conceived as a single-seat fighter, the Fa 269 project resulted from a design study order issued by the Reich Air Ministry to Focke-Achgelis in 1941. The order called for a local defence fighter which would combine the VTOL capabilities of a helicopter with the speed and economy of a conventional fixed-wing aircraft. A large amount of wind tunnel testing was undertaken, along with work on gearboxes, drives and power-pivoting mechanisms, and a full-scale mock-up of the aircraft was built to demonstrate the VTOL concept, but much of this was destroyed by Allied bombing raids and all work was shelved in 1944, when Focke-Achgelis estimated that there was little likelihood of a practical prototype being available before 1947. Design A mid-wing monoplane, the Fa 269 was to have been powered by a single BMW 801 air-cooled radial engine buried in the fuselage behind the cockpit, which ...
