Maupin Carbon Dragon
The Maupin Carbon Dragon is an American, high-wing, single-seat, glider that was designed by Jim Maupin and made available as plans for amateur construction. Plans are no longer available.Maupin, Jim: ''Carbon Dragon'', sales brochure, October 1988Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003–04'', p. 57. Pagefast Ltd, Lancaster OK, 2003. ISSN 1368-485X Design and development The Carbon Dragon was intended to take advantage of the US FAR 103 Ultralight Vehicles regulations that classify unpowered aircraft with empty weights of or less as hang gliders and thus allow them to be flown without a pilot license, Federal Aviation Administration aircraft registration or a Certificate of Airworthiness. The Carbon Dragon's standard empty weight is and the aircraft has a gross weight of , giving a payload of . The designer said "The philosophy behind its development was to try to bring foot launch soaring performance up into the lower performance ran ...

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 ...

Irv Culver
Irven Harold Culver (May 11, 1911 – August 13, 1999) was an American aeronautical engineer. Most notable of all his accomplishments, Culver is credited for solving a fatal flaw in the Lockheed P-38, related to high-speed compressibility problems which killed a test pilot. A humorous episode during World War II resulted in giving the very secret Lockheed Advanced Development Projects division the name "Skunk Works". A phone call from the U.S. Department of the Navy to W. A. "Dick" Pulver was misdirected to Irv Culver who answered the phone with "Skonk Works, inside man Culver" and the name stuck. Another variant of the story relates that the original Skunk Works was located in a circus tent adjacent to the Lockheed plastics fabrication facility which smelled bad and reminded the engineers of the '' L'il Abner'' comic strip. Reportedly, Culver showed up for work wearing a civil defense gas mask as a gag and when he answered the phone he said "Skonk Works" referring to the car ...

Maupin Windrose
The Maupin Windrose is an American high-wing, single-seat glider and motor glider that was designed by Jim Maupin for the Sailplane Homebuilders Association Design Contest.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 68, Soaring Society of America November 1983. USPS 499-920 Design and development Maupin designed the Windrose as an easy-to-construct, safe, self-launching, low-cost and aesthetically pleasing aircraft project that could be flown as a pure glider or a powered glider. The design has many innovative features and is of mixed construction using wood, foam and fiberglass. The wing is carved from solid foam and covered in fiberglass. There is no spar and instead the wing employs bands of unidirectional roving epoxied under the outer skin and joined by vertical dowels to take the compression loads from the underlying foam. The wing is of a span or, optionally, a span, and uses an Irv Culver custom airfoil. The ailerons are controlled from their in ...

Spoiler (aeronautics)
In aeronautics, a spoiler (sometimes called a lift spoiler or lift dumper) is a device which intentionally reduces the lift (force), lift component of an airfoil in a controlled way. Most often, spoilers are plates on the top surface of a wing that can be extended upward into the airflow to ''spoil'' the streamline flow. By so doing, the spoiler creates a controlled Stall (flight), stall over the portion of the wing behind it, greatly reducing the lift of that wing section. Spoilers differ from air brake (aeronautics), airbrakes in that airbrakes are designed to increase drag without disrupting the lift distribution across the wing span, while spoilers disrupt the lift distribution as well as increasing drag. Spoilers fall into two categories: those that are deployed at controlled angles during flight to increase descent rate or control roll, and those that are fully deployed immediately on landing to greatly reduce lift ("lift dumpers") and increase drag. In modern fly-by- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bungee Launch
Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than are achieved. Some competitive pilots fly in races around pre-defined courses. These gliding competitions test pilots' abilities to ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

G-force
The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth, ''g'', of about . Since g-forces indirectly produce weight, any g-force can be described as a "weight per unit mass" (see the synonym specific weight). When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite weight for every unit of each object's mass. The types of forces involved are transmitted through objects by interior mechanical stresses. Gravitational acceleration (except certain electromagnetic force influences) is the cause of an object's acceleration in relation to free fall. The g-force experienced by an object is due to the vector sum of all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mahogany
Mahogany is a straight-grained, reddish-brown timber of three tropical hardwood species of the genus ''Swietenia'', indigenous to the AmericasBridgewater, Samuel (2012). ''A Natural History of Belize: Inside the Maya Forest''. Austin: University of Texas Press. pp. 164–165. . and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature. It is naturally found within the Americas, but has also been imported to plantations across Asia and Oceania. The mahogany trade may have begun as early as the 16th century and flourished in the 17th and 18th centuries. In certain countries, mahogany is considered an invasive species. Description The three species are: *Honduran or big-leaf mahogany ('' Swietenia macrophylla''), with a range from Mexico to southern Amazonia in Brazil, the most widespread species of mahogany and the only genuine mahogany species commercially grown today.

Spar (aviation)
In a fixed-wing aircraft, the spar is often the main structural member of the wing, running spanwise at right angles (or thereabouts depending on wing sweep) to the fuselage. The spar carries flight loads and the weight of the wings while on the ground. Other structural and forming members such as ribs may be attached to the spar or spars, with stressed skin construction also sharing the loads where it is used. There may be more than one spar in a wing or none at all. Where a single spar carries most of the force, it is known as the main spar. Spars are also used in other aircraft aerofoil surfaces such as the tailplane and fin and serve a similar function, although the loads transmitted may be different from those of a wing spar. Spar loads The wing spar provides the majority of the weight support and dynamic load integrity of cantilever monoplanes, often coupled with the strength of the wing 'D' box itself. Together, these two structural components collectively provide the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Side Stick
__NOTOC__ A side-stick or sidestick controller is an aircraft control stick that is located on the side console of the pilot, usually on the righthand side, or outboard on a two-seat flightdeck. Typically this is found in aircraft that are equipped with fly-by-wire control systems.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 463. Aviation Supplies & Academics, 1997. The throttle controls are typically located to the left of a single pilot or centrally on a two-seat flightdeck. Only one hand is required to operate it; two hand operation is neither possible nor necessary. The side-stick is used in many modern military fighter aircraft, such as the F-16 Fighting Falcon, Mitsubishi F-2, Dassault Rafale, and F-22 Raptor, and also on civil aircraft, such as the Sukhoi Superjet 100, Airbus A320 and all subsequent Airbus aircraft, including the largest passenger jet in service, the Airbus A380. It is also used in new helicopter models such as the Bell 525. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
