Pitts Sky Car
The Pitts Sky Car was an unsuccessful aircraft designed for vertical take off, by inventor John W. Pitts of Detroit, Michigan. Pitts filed a United States Patent in 1924 for a propeller, "which will cause an immediate vertical lift of any aerial car to which the propeller is attached". This consisted of a "mushroom-shaped" rotor of 60 blades, each hinged at the root. An engine would rotate and reciprocate the propeller, causing the blades to close on the downstroke and open on the upstroke, which it was hoped would induce lift. The patent was granted in October 1926. In collaboration with W. P. Kindree, Pitts constructed a prototype with a Curtiss OX-5 engine. A newsreel of 1928 shows the Sky Car attempting to fly; however rather than take off, it merely jumps up and down. Vimeo] In popul ...

Newsreel
A newsreel is a form of short documentary film, containing news stories and items of topical interest, that was prevalent between the 1910s and the mid 1970s. Typically presented in a cinema, newsreels were a source of current affairs, information, and entertainment for millions of moviegoers. Newsreels were typically exhibited preceding a feature film, but there were also dedicated newsreel theaters in many major cities in the 1930s and ’40s, and some large city cinemas also included a smaller theaterette where newsreels were screened continuously throughout the day. By the end of the 1960s television news broadcasts had supplanted the format. Newsreels are considered significant historical documents, since they are often the only audiovisual record of certain cultural events. History Silent news films were shown in cinemas from the late 19th century. In 1909 Pathé started producing weekly newsreels in Europe. Pathé began producing newsreels for the UK in 1910 and ...

Those Magnificent Men In Their Flying Machines
''Those Magnificent Men in their Flying Machines; Or, How I Flew from London to Paris in 25 Hours and 11 Minutes'' is a 1965 British period comedy film that satirizes the early years of aviation. Directed and co-written by Ken Annakin, the film stars an international ensemble cast, including Stuart Whitman, Sarah Miles, Robert Morley, Terry-Thomas, James Fox, Red Skelton, Benny Hill, Jean-Pierre Cassel, Gert Fröbe and Alberto Sordi. Based on a screenplay entitled ''Flying Crazy'', the fictional account is set in 1910, when English press magnate Lord Rawnsley offers £10,000 () to the winner of the ''Daily Post'' air race from London to Paris to prove that Britain is "number one in the air". Plot A brief narration outlines man's first attempts to fly since the Stone Age inspired by a bird's flight, seen with footage from the silent film era, and man being represented by a "test pilot" (Red Skelton) encountering periodic misfortune in his attempts.

Cyclogyro
The cyclogyro, or cyclocopter, is an aircraft configuration that uses a horizontal-axis cyclorotor as a rotor wing to provide lift and sometimes also propulsion and control. In principle, the cyclogyro is capable of vertical take off and landing and hovering performance like a helicopter, while potentially benefiting from some of the advantages of a fixed-wing aircraft. The cyclogyro is distinct from the Flettner airplane which uses a cylindrical wing rotor to harness the Magnus effect. Principles of operation The cyclogyro wing resembles a paddle wheel, with airfoil blades replacing the paddles. Like a helicopter, the blade pitch (angle of attack) can be adjusted either collectively all together or cyclically as they move around the rotor's axis. In normal forward flight the blades are given a slight positive pitch at the upper and forward portions of their arc producing lift and, if powered, also forward thrust. They are given flat or negative pitch at the bottom, and are "fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithopter
An ornithopter (from Greek ''ornis, ornith-'' "bird" and ''pteron'' "wing") is an aircraft that flies by flapping its wings. Designers sought to imitate the flapping-wing flight of birds, bats, and insects. Though machines may differ in form, they are usually built on the same scale as flying animals. Larger, crewed ornithopters have also been built and some have been successful. Crewed ornithopters are generally either powered by engines or by the pilot. Early history Some early crewed flight attempts may have been intended to achieve flapping-wing flight, but probably only a glide was actually achieved. They include the purported flights of the 11th-century Catholic monk Eilmer of Malmesbury (recorded in the 12th century) and the 9th-century poet Abbas Ibn Firnas (recorded in the 17th century). Roger Bacon, writing in 1260, was also among the first to consider a technological means of flight. In 1485, Leonardo da Vinci began to study the flight of birds. He grasped that human ...

The Gerhardt Cycleplane has been called the world's first successful human-powered aircraft.Cornelisse, Diana G. ''Splendid Vision, Unswerving Purpose: Developing Air Power for the United States Air Force During the First Century of Powered Flight''. Wright-Patterson Air Force Base, Ohio: U.S. Air Force Publications, 2002. . It was designed by Dr. William Frederick Gerhardt (January 31, 1896 – March 15, 1984), and assembled by the staff of the Flight Test Section at McCook Field in Dayton, Ohio. It was flown in 1923. History The Gerhardt Cycleplane was developed in 1923 by Dr. William F. Gerhardt, head of the Aeronautical Engineering Department at the University of Michigan. While working as an aeronautical engineer at McCook Field, Dr. Gerhardt designed the Cycleplane during his off-duty hours. The Cycleplane was one of many civilian aircraft projects developed at McCook Field by the base's engineers and test staff. The concept was to produce an aircraft capable of maintainin ...

Curtiss OX-5
The Curtiss OX-5 was an early V-8 American liquid-cooled aircraft engine built by Curtiss. It was the first American-designed aircraft engine to enter mass production, although it was considered obsolete when it did so in 1917.Smith, 1981, page 46 It nevertheless found widespread use on a number of aircraft, perhaps the most famous being the JN-4 "Jenny". Some 12,600 units were built through early 1919. The wide availability of the engine in the surplus market made it common until the 1930s, although it was considered unreliable for most of its service life. Design and development The OX-5 was the last in a series of Glenn Curtiss designed V engines, which started as a series of air-cooled V-twins for motorcycles in 1902. A modified version of one of these early designs was sold as an aircraft engine in 1906, and from then on the company's primary market was aircraft. The basic design had slowly expanded by adding additional cylinders until they reached the V-8 in 1906. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 aro ...
