Murphy JDM-8
The Murphy JDM-8 is a Canadian single-seat ultralight monoplane designed by Daryl Murphy. The type was intended to be sold as a kit for home construction by Murphy Aircraft of Chilliwack, British Columbia.Levy, Howard: ''Daryl Murphy's Latest'', Kitplanes, Volume 20, Number 1, January 2003, pages 10-12. Primedia Publications. ISSN 0891-1851 The designation indicates the designer's initials, J. Daryl Murphy and his eighth design. Design and development Work was begun on the JDM-8 design in December 1998, but the project was not a high priority and so did not fly until March 2001. The aircraft was first publicly shown at Sun 'n Fun 2000 when it was not yet complete. The JDM-8 is an all-metal low-wing cantilever monoplane designed in two variants, one to meet the American FAR 103 Ultralight Vehicles regulations and one for the non-American markets particularly Canada and Europe. The JDM-8 has a conventional landing gear with a tailwheel and can be powered by a Rotax engine fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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".

Bungee Cord
Bungee cords equipped with metal hooks A bungee cord (sometimes spelled bungle; also known as a shock cord) is an elastic cord composed of one or more elastic strands forming a core, usually covered in a woven cotton or polypropylene sheath. The sheath does not materially extend elastically, but it is braided with its strands spiralling around the core so that a longitudinal pull causes it to squeeze the core, transmitting the core's elastic compression to the longitudinal extension of the sheath and cord. Specialized bungees, such as some used in bungee jumping, may be made entirely of elastic strands. Uses upA child on a bungee cord device in Moscow, Russia Bungee cords have been used to provide a lightweight suspension for aircraft undercarriages from before World War I, and are still used on many small homebuilt aircraft where weight remains critical. Bungee cords were also used in parachuting to assist in opening the old-style parachute container after the ripcord wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transport Canada
Transport Canada (french: Transports Canada) is the department within the Government of Canada responsible for developing regulations, policies and services of road, rail, marine and air transportation in Canada. It is part of the Transportation, Infrastructure and Communities (TIC) portfolio. The current Minister of Transport is Omar Alghabra. Transport Canada is headquartered in Ottawa, Ontario. History The Department of Transport was created in 1935 by the government of William Lyon Mackenzie King in recognition of the changing transportation environment in Canada at the time. It merged three departments: the former Department of Railways and Canals, the Department of Marine, and the Civil Aviation Branch of the Department of National Defence (c. 1927 when it replaced the Air Board) under C. D. Howe, who would use the portfolio to rationalize the governance and provision of all forms of transportation (air, water and land). He created a National Harbours Board and Trans-C ...

Basic Ultralight
The Canadian Aviation Regulations define two types of ultralight aircraft: basic ultra-light aeroplane (BULA), and advanced ultra-light aeroplane (AULA). Definition Regulation of ultra-light aircraft in Canada is covered by the Canadian Aviation Regulations. An earlier definition of "ultra-light aeroplane", effective October 10, 1996, meant: * a single-seat aeroplane that has a launch weight of 165 kg (364 pounds) or less, and a wing area, expressed in square metres, of not less than the launch weight in kilograms minus 15, divided by 10, and in no case less than , * a two-seat instructional aeroplane that has a launch weight of 195 kg (430 pounds) or less, and a wing area, expressed in square metres, of not less than 10 m2 and a wing loading of not more than 25 kg/m2 (5.12 lb/ft2), the wing loading being calculated using the launch weight plus the occupant weight of 80 kg (176 pounds) per person, or * an advanced ultra-light aeroplane; On June 1, 2 ...

Light-sport Aircraft
A light-sport aircraft (LSA), or light sport aircraft, is a fairly new category of small, lightweight aircraft that are simple to fly. LSAs tend to be heavier and more sophisticated than ultralight (aka "microlight") aircraft, but LSA restrictions on weight and performance separates the category from established GA aircraft. There is no standard worldwide description of an LSA . LSAs in different countries The civil aviation authorities in different countries have their own particular specifications and regulations which define the LSA category. For example, in Australia the Civil Aviation Safety Authority defines a light-sport aircraft as a heavier-than-air or lighter-than-air craft, other than a helicopter, with a maximum gross takeoff weight of not more than for lighter-than-air craft; for heavier-than-air craft not intended for operation on water; or for aircraft intended for operation on water. It must have a maximum stall speed of in landing configuration; a maximum ... [...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] |
Tailplane
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydroformed
Hydroforming is a cost-effective way of shaping ductile metals such as aluminium, brass, low alloy steel, and stainless steel into lightweight, structurally stiff and strong pieces. One of the largest applications of hydroforming is the automotive industry, which makes use of the complex shapes made possible by hydroforming to produce stronger, lighter, and more rigid unibody structures for vehicles. This technique is particularly popular with the high-end sports car industry and is also frequently employed in the shaping of aluminium tubes for bicycle frames. Hydroforming is a specialized type of die forming that uses a high pressure hydraulic fluid to press room temperature working material into a die. To hydroform aluminium into a vehicle's frame rail, a hollow tube of aluminium is placed inside a negative mold that has the shape of the desired result. High pressure hydraulic pumps then inject fluid at very high pressure inside the aluminium tube which causes it to expand ...

Trailing Edge
The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge meets.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 521. Aviation Supplies & Academics, 1997. Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft. Such control surfaces include ailerons on the wings for roll control, elevators on the tailplane controlling pitch, and the rudder on the fin controlling yaw. Elevators and ailerons may be combined as elevons on tailless aircraft. The shape of the trailing edge is of prime importance in the aerodynamic function of any aerodynamic surface. George Batchelor has written about: :“ ... the remarkable controlling influence exerted by the sharp trailing edge of an aerofoil on the circulation.”Batchelor, G. K. (1967), ''An Introduction to Fluid Dynamics'', p.438, Cambridge University Press. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the result o ...
