MIT Monarch A
The ''Monarch A'' was a human-powered aircraft, designed and built by graduates and undergraduates of the Massachusetts Institute of Technology, with Professors Walter Hollister and Ed Crawley acting as Project Advisers. Professor Eugene Larrabee, who had been the adviser for the 1979 MIT ''Chrysalis'' HPA, also provided support. Development The concept and general arrangement of the craft, described as an improved successor to the ''Chrysalis'', was first detailed in the Spring 1981 issue of the ''AIAA Student Journal''. Development of the design was prompted in May 1983 by the announcement of the Kremer World Speed Competition. According to the rules, the first HPA to traverse a 1,500 m (4,920 ft) triangular closed course in less than 180 seconds would be awarded a £20,000 prize. Competition rules allowed for stored energy, generated by the pilot during a ten-minute period immediately preceding a flight, to be used as an additional power source. Design of th ...

Human-powered Aircraft
A human-powered aircraft (HPA) is an aircraft belonging to the class of vehicles known as human-powered transport. Human-powered aircraft have been successfully flown over considerable distances. However, they are still primarily constructed as engineering challenges rather than for any kind of recreational or utilitarian purpose. History Early attempts at human-powered flight were unsuccessful because of the difficulty of achieving the high power-to-weight ratio. Prototypes often used ornithopter principles which were not only too heavy to meet this requirement but aerodynamically unsatisfactory. First attempts In 1904, Scientific American published an article and a photograph of a bicycle plane built by Steward Winslow of Riparia, Washington. He attempted to fly his plane on 30 July 1904, but one of the wheels failed. An early human-powered aircraft was the Gerhardt Cycleplane, developed by W. Frederick Gerhardt at McCook Field in Dayton, Ohio in 1923. The aircr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanscom Field
Laurence G. Hanscom Field , commonly known as Hanscom Field, is a public use airport operated by the Massachusetts Port Authority, located outside Boston in Bedford, Massachusetts, United States. Hanscom is mainly a general aviation airport, the largest in New England. Both runways can accommodate jets, and are used by Hanscom Air Force Base, a defense-research facility next to Hanscom Field. It is a popular training airport, with more than 40 rental aircraft on the field. The Civil Air Terminal building hosts two flight schools. Transient general aviation planes are served by three FBOs: Jet Aviation, Rectrix Aviation, and Signature Flight Support. Federal Aviation Administration records say the airport had 10,956 passenger boardings (enplanements) in calendar year 2017. It is in the National Plan of Integrated Airport Systems for 2021–2025, in which the FAA categories it as a ''non-primary commercial service'' airport (between 2,500 and 10,000 enplanements per year).

Aircraft First Flown In 1983
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 jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-a ...

1980s United States Experimental Aircraft
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 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.

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

MIT Daedalus
The MIT Aeronautics and Astronautics Department's Daedalus was a human-powered aircraftJohn McIntyreMan's Greatest Flight, ''AeroModeller'', August 1988 (in files of Royal Aeronautical Society Human Powered Aircraft Group) (accessed Nov. 13 2012) that, on 23 April 1988, flew a distance of 72.4 mi (115.11 km) in 3 hours, 54 minutes, from Heraklion on the island of Crete to the island of Santorini. The flight holds official FAI world records for total distance, straight-line distance, and duration for human-powered aircraft. The craft was named after the mythological inventor of aviation, Daedalus, and was inspired by the Greek myth of Daedalus' escape from Crete using manmade wings. There were actually three aircraft constructed: * ''Light Eagle'' (originally ''Michelob Light Eagle''): a 42 kg (92 lb) prototype. * ''Daedalus 87'': Crashed during testing at Rogers Dry Lake (NASA Dryden Flight Research Center) on 17 February 1988, and was rebuilt as a backu ...

MacCready Gossamer Condor
The MacCready ''Gossamer Condor'' was the first human-powered aircraft capable of controlled and sustained flight; as such, it won the Kremer prize in 1977. Its design was led by Paul MacCready of AeroVironment, Inc. Design and development The Kremer Prize had been set up in 1959 by Henry Kremer, a British industrialist, and offered £50,000 in prize money to the first group that could fly a human-powered aircraft over a figure-eight course covering a total of one mile (1.6 kilometers). The course also included a ten-foot pole that the aircraft had to fly over at the start and at the end. Early attempts to build human-powered aircraft had focused on wooden designs, which proved too heavy. Very early attempts – notably the ' and ''Pedaliante'' – used catapult launches. In 1961, Southampton University's Man Powered Aircraft SUMPAC took to the air at Lasham Airfield on 9 November, piloted by Derek Piggott, achieving a maximum flight of 650 metres. One week later, on 16 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MacCready Gossamer Albatross
The ''Gossamer Albatross'' is a human-powered aircraft built by American aeronautical engineer Dr Paul B MacCready's company AeroVironment. On June 12, 1979, it completed a successful crossing of the English Channel to win the second Kremer prize worth £100,000 (). Design and development The aircraft was designed and built by a team led by Paul B. MacCready, a noted American aeronautics engineer, designer, and world soaring champion. ''Gossamer Albatross'' was his second human-powered aircraft, the first being the ''Gossamer Condor'', which had won the first Kremer prize on August 23, 1977, by completing a -long figure-eight course. The second Kremer challenge was then announced as a flight across the English Channel recalling Louis Blériot's crossing of 1909. The aircraft is of "canard" configuration, using a large horizontal stabilizer forward of the wing in a manner similar to the Wright brothers' successful ''Wright Flyer'' aircraft and powered using pedals to drive a ...

Kohm Lady Godiva
The ''Lady Godiva'' is a human-powered aircraft built in the early 1980s by Thomas Kohm of Huntington, New York. It is a replica of the MacCready ''Gossamer Albatross''. Kohm had been a physics teacher at Cold Spring Harbor High School and, along with a group of his students, was inspired by the success of the ''Albatross'' to make a copy of it. As their project advanced, Kohm decided that the craft would be the "first girl-powered plane", with the role of pilot eventually being taken by his teenage daughter, Christina 'Christy' Kohm. The craft acquired the name '' Lady Godiva'', due to her wearing minimal clothing, when she was piloting the craft. Construction began in 1981, with the first flight taking place at the Brookhaven Municipal Airport in July 1982. The best flight occurred on October 1, 1982, when it flew for 4 minutes 30 seconds. The aircraft was constructed from graphite fibre tubing, mylar, stryofoam, and balsa. It was modified three times, and also underw ...

Bedford, Massachusetts
Bedford is a town in Middlesex County, Massachusetts, United States. The population of Bedford was 14,383 at the time of the 2020 United States Census. History ''The following compilation comes from Ellen Abrams (1999) based on information from Abram English Brown's ''History of the Town of Bedford'' (1891), as well as other sources such as ''The Bedford Sampler Bicentennial Edition'' containing Daisy Pickman Oakley's articles, Bedford Vital Records, New England Historical and Genealogical Register, Town Directories, and other publications from the Bedford Historical Society.'' The land now within the boundaries of Bedford was first settled by Europeans around 1640. In 1729 it was incorporated from a portion of Concord (about 2/5 of Bedford) and a portion of Billerica (about 3/5 of Bedford). In 1630, John Winthrop and Thomas Dudley of the Massachusetts Bay Company arrived aboard the ''Arabella'' from Yarmouth, England. After a difficult ten-week voyage, they landed o ...
