VZ-1 Pawnee
The Hiller VZ-1 Pawnee (U.S. Army designation; earlier Army designation: HO-1) was a unique direct-lift rotor aircraft, using contra-rotating ducted fans for lift inside a platform upon which the single pilot shifted body weight for directional control. The platform was developed starting in 1953 under an Office of Naval Research (ONR) contract to Hiller Aircraft, and flew successfully beginning in 1955. Design and development The original concept had been developed by Charles H. Zimmerman in the late 1940s. Further development followed, both by Hiller Aircraft and the De Lackner Company. There were two main models, the ONR model 1031-A-1, and the somewhat larger VZ-1 Pawnee model produced in 1956 for the U.S. Army. Three of each model were built as prototypes. Neither of the variants was put into production. The smaller ONR model used two Nelson H-59 piston engines, coupled to the propellers by a modified helicopter transmission built by the Industrial Power Division of Hal ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

1950s United States Experimental Aircraft
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Rotorcraft
A rotorcraft or rotary-wing aircraft is a heavier-than-air aircraft with rotary wings or rotor blades, which generate lift by rotating around a vertical mast. Several rotor blades mounted on a single mast are referred to as a rotor. The International Civil Aviation Organization (ICAO) defines a rotorcraft as "supported in flight by the reactions of the air on one or more rotors". Rotorcraft generally include aircraft where one or more rotors provide lift throughout the entire flight, such as helicopters, autogyros, and gyrodynes. Compound rotorcraft augment the rotor with additional thrust engines, propellers, or static lifting surfaces. Some types, such as helicopters are capable of vertical takeoff and landing. An aircraft which uses rotor lift for vertical flight but changes to solely fixed-wing lift in horizontal flight is not a rotorcraft but a convertiplane. Classes of rotorcraft Helicopter A helicopter is a rotorcraft whose rotors are driven by the engine(s) throughout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiller Aircraft
Hiller Aircraft Company was founded in 1942 as Hiller Industries by Stanley Hiller to develop helicopters. History Stanley Hiller, then seventeen, established the first helicopter factory on the West Coast of the United States, located in Berkeley, California, in 1942, under the name "Hiller Industries," to develop his design for the coaxial-rotor XH-44 "Hiller-Copter" for the U.S. Army. The XH-44 became operational in 1944.Hiller Helicoptertimeline(accessed Nov 9 2011) In collaboration with Henry J. Kaiser, it became United Helicopters in 1945. In the postwar years, United Helicopter produced a number of innovative helicopter designs for military and civilian purposes, including coaxial-rotor and tailless designs, as well as more conventional models. In January, 1949, a Hiller 360 became the first civilian helicopter to cross the United States. Besides helicopters, in the year after World War II, Stanley Hiller researched a two-man rocket-jet aircraft design that took off ...

Williams X-Jet
The Williams X-Jet, created by Williams International, was a small, single-person, light-weight, Vertical Take Off and Landing (VTOL) aircraft powered by a modified Williams F107 turbofan aircraft engine — designated WR-19-7 — after some minor modifications. The vehicle was nicknamed "The Flying Pulpit" for its shape. It was designed to carry one operator and to be controlled by leaning in the direction of desired travel and by modulating engine output power. It could move in any direction, accelerate rapidly, hover and rotate on its axis, stay aloft for up to 45 minutes and travel at speeds up to 60 miles per hour (97 km/h). It was evaluated by the United States Army in the 1980s, but was deemed inferior to the capabilities of helicopters and small, unmanned aircraft, and so the development of the X-Jet was discontinued. Other VTOL systems developed by Williams International included a jet-powered flying belt, developed in 1969, which was powered by a Williams WR19 ...

De Lackner HZ-1 Aerocycle
The HZ-1 Aerocycle, also known as the YHO-2 and by the manufacturer's designation DH-5 Aerocycle, was an American one-man "personal helicopter" developed by de Lackner Helicopters in the mid-1950s. Intended to be operated by inexperienced pilots with a minimum of 20 minutes of instruction, the HZ-1 was expected to become a standard reconnaissance machine with the United States Army. Although early testing showed that the craft had promise for providing mobility on the atomic battlefield, more extensive evaluation proved that the aircraft was in fact too difficult to control for operation by untrained infantrymen, and after a pair of crashes the project was abandoned. A single model of the craft was put on display. Design and development During the early 1950s, Charles H. Zimmerman of the National Advisory Committee for Aeronautics (NACA) developed a system for control of a rotorcraft in which, with the rotors mounted on the underside of the aircraft, the machine could be st ...

Bensen B-10
The Bensen B-10 Propcopter was an unconventional VTOL aircraft developed by Igor Bensen in the United States in the late 1950s. The pilot sat astride a beam that had an engine mounted at either end of it, each driving a rotor to provide lift. Each of these rotors was surrounded by a system of four pivotable vanes to direct its downwash In aeronautics, downwash is the change in direction of air deflected by the aerodynamic action of an airfoil, wing, or helicopter rotor blade in motion, as part of the process of producing lift.Crane, Dale: ''Dictionary of Aeronautical Terms, thir ..., and linked to a control stick for the pilot, this provided control of the craft. Only a single prototype (registered ''N56U'') was built.
