Transcendental Model 1-G
The Transcendental Model 1-G was an experimental American tiltrotor prototype of the 1950s. It was a single-seat aircraft powered by a single piston engine, and was the first tiltrotor to fly.Norton ''Air Enthusiast'' 2005, p. 49. A single example was built, which was destroyed in a crash in 1955. Design and development The Transcendental Aircraft Company was founded in January 1947 at New Castle, Delaware by Mario Guerrieri and Bob Lichten, two employees of Kellett Autogiro Corporation, Kellet Aircraft, to develop the Model 1-G, on which they had begun design work in 1945. Their design was a small Cantilever#Aircraft, cantilever monoplane powered by a single Lycoming O-290-A air-cooled flat-four engine positioned in the fuselage that drove two 3-blade rotors at the tips of the wings via a two-speed reduction gearbox. Two electric motors were used to tilt the rotors, with the rotors linked by a shaft running through the wing to ensure that both rotors would be tilted at the same ...

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 ...

Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and ...

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. Events By place Roman Empire * Emperor Septimius Severus has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger.

Tiltrotor Aircraft
A tiltrotor is an aircraft which generates lift and propulsion by way of one or more powered rotors (sometimes called ''proprotors'') 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. Tiltrotor design combines the VTOL capability of a helicopter with the speed and range of a conventional fixed-wing aircraft. For vertical flight, the rotors are angled so the plane of rotation is horizontal, generating lift the way a normal helicopter rotor does. As the aircraft gains speed, the rotors are progressively tilted forward, with the plane of rotation eventually becoming vertical. In this mode the rotors provide thrust as a propeller, and the airfoil of the fixed wings takes over providing the lift via the forward motion of the entire aircraft. Since the rotors can be configured to be more efficient for propulsion (e.g. with root-tip twist) and it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Enthusiast
''Air Enthusiast'' was a British, bi-monthly, aviation magazine, published by the Key Publishing group. Initially begun in 1974 as ''Air Enthusiast Quarterly'', the magazine was conceived as a historical adjunct to '' Air International'' magazine. ''Air International'' was (and still is) involved with current aviation topics and the ''Quarterly'' concerned itself with historical matters. Each issue contained 80 pages; as a result certain articles were divided and each part appeared over a number of issues. ''Air Enthusiast'' was illustrated with colour and black-and-white photos, diagrams, profiles and three-view drawings. Earlier issues featured cutaway drawings, but these were dropped. The articles provided detail for varieties of aircraft An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from ...

Bell XV-3
The Bell XV-3 (Bell 200) is an American tiltrotor aircraft developed by Bell Helicopter for a joint research program between the United States Air Force and the United States Army in order to explore convertiplane technologies. The XV-3 featured an engine mounted in the fuselage with driveshafts transferring power to two-bladed rotor assemblies mounted on the wingtips. The wingtip rotor assemblies were mounted to tilt 90 degrees from vertical to horizontal, designed to allow the XV-3 to take off and land like a helicopter but fly at faster airspeeds, similar to a conventional fixed-wing aircraft. The XV-3 was first flown on 11 August 1955. Although it was limited in performance, the aircraft successfully demonstrated the tiltrotor concept, accomplishing 110 transitions from helicopter to airplane mode between December 1958 and July 1962. The XV-3 program ended when the remaining aircraft was severely damaged in a wind tunnel accident on 20 May 1966. The data and experience from ...

Lift (force)
A fluid flowing around an object exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the force parallel to the flow direction. Lift conventionally acts in an upward direction in order to counter the force of gravity, but it can act in any direction at right angles to the flow. If the surrounding fluid is air, the force is called an aerodynamic force. In water or any other liquid, it is called a hydrodynamic force. Dynamic lift is distinguished from other kinds of lift in fluids. Aerostatic lift or buoyancy, in which an internal fluid is lighter than the surrounding fluid, does not require movement and is used by balloons, blimps, dirigibles, boats, and submarines. Planing lift, in which only the lower portion of the body is immersed in a liquid flow, is used by motorboats, surfboards, windsurfers, sailboats, and water-skis. Overview A fluid flowing arou ...

Bellanca Airfield
The Bellanca Airfield was an airfield, aircraft plant, and service hangar built in 1928 by Giuseppe Bellanca and Henry B. DuPont in New Castle, Delaware. Located off Route 273 near the Delaware River, the plant produced approximately 3000 aircraft before closing in 1954. The only surviving part of the airfield is the former Air Service, Inc. hangar, which was listed on the National Register of Historic Places in 2005. History Giuseppe Mario Bellanca immigrated from Italy in 1912 and continued his passion for aircraft design in the United States. His aircraft achieved numerous endurance and efficiency records. His $25,000 WB-2 monoplane, ''Columbia'', was the first choice of Charles Lindbergh for his trans-Atlantic flight after, on April 25, 1927, Clarence Duncan Chamberlin, Clarence Chamberlin and Bertrand Blanchard Acosta, Bert Acosta set the world endurance record for aircraft, staying aloft circling New York City for 51 hours, 11 minutes, and 25 seconds and covering 4,100 mi ...
