Bensen B-12
The Bensen B-12, variously dubbed the Sky-Way or Sky-Mat was an unconventional multirotor developed by Igor Bensen in the United States in the late 1950s. Extremely unorthodox, the design sprang from Bensen's thinking about the engine redundancy necessary to ensure the safe operation of small, personal rotorcraft operating at low altitudes and slow speeds. The result was a broad aluminum framework supporting an array of ten engines and rotors that Bensen likened to a "magic carpet A magic carpet, also called a flying carpet, is a legendary carpet and common trope in fantasy fiction. It is typically used as a form of transportation and can quickly or instantaneously carry its users to their destination. In literature One o ...".Bensen 1992, 110 The design was later refined to include eight rotors, each driven by two engines for a total of sixteen. Successfully flown in 1961 at altitudes up to 20 ft (6 m), Bensen felt that the approach had potential for military heavy-lift ...

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".

Igor Bensen
Igor Vasilevich Bensen (russian: И́горь Васи́льевич Бенсен; April 1, 1917 – February 10, 2000) was a Russian-American engineer. He founded Bensen Aircraft, a US company which produced a successful line of gyrogliders (rotor kites) and autogyros. Early life and education He was born in Rostov-on-Don, Russia, and eventually reached the United States in 1937. He began studies at age 17 while in Belgium, won a scholarship to study in the US three years later. He received a Bachelor of Science degree in mechanical engineering from Stevens Institute of Technology in Hoboken, New Jersey in 1940, later becoming a Registered Professional Engineer. Career Bensen flew his first towed gyroglider in 1954. He founded the Popular Rotorcraft Association (PRA) in 1962, a non-profit interest group for owners and homebuilders of autogyros and helicopters, based in Mentone, Indiana. He was the group's president from 1962 to 1971. Honors and awards He received an hon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multirotor
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 ...

Redundancy (engineering)
In engineering, redundancy is the intentional duplication of critical components or functions of a system with the goal of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing. In many safety-critical systems, such as fly-by-wire and hydraulic systems in aircraft, some parts of the control system may be triplicated, which is formally termed triple modular redundancy (TMR). An error in one component may then be out-voted by the other two. In a triply redundant system, the system has three sub components, all three of which must fail before the system fails. Since each one rarely fails, and the sub components are expected to fail independently, the probability of all three failing is calculated to be extraordinarily small; it is often outweighed by other risk factors, such as human error. Redundancy may also be known by the terms "m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magic Carpet
A magic carpet, also called a flying carpet, is a legendary carpet and common trope in fantasy fiction. It is typically used as a form of transportation and can quickly or instantaneously carry its users to their destination. In literature One of the stories in the ''One Thousand and One Nights'' relates how Prince Husain, the eldest son of Sultan of the Indies, travels to Bisnagar (Vijayanagara) in India and buys a magic carpet. This carpet is described as follows: "Whoever sitteth on this carpet and willeth in thought to be taken up and set down upon other site will, in the twinkling of an eye, be borne thither, be that place nearhand or distant many a day's journey and difficult to reach." The literary traditions of several other cultures also feature magical carpets, in most cases literally flying rather than instantly transporting their passengers from place to place. Solomon's carpet was reportedly made of green silk with a golden weft, long and wide: "when Solomon sat u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
