Motor Glider
A motor glider is a fixed-wing aircraft that can be flown with or without engine power. The FAI Gliding Commission Sporting Code definition is: a fixed-wing aerodyne equipped with a means of propulsion (MoP), capable of sustained soaring flight without thrust from the means of propulsion. History In 1935, an occasional or auxiliary motor that could be retracted was suggested by Sir John Carden. This was incorporated into the Carden-Baynes Auxiliary that first flew on 8 August of the same year. A later version of the Budig glider was powered. Categories Most motor gliders are equipped with a propeller, which may be fixed, feathered (e.g. AMS-Flight Carat), or retractable. However jet engine-powered motorgliders are now available from some manufacturers, some of which are intended for use only as "sustainer" engines, i.e. for sustaining gliding flight rather than as self-launching aircraft. Sustainer motor gliders Sustainer motor gliders must be launched like an unpowere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DG Flugzeugbau DG-808B
The DG Flugzeugbau DG-800 series is a family of FAI 15 metre Class, 15 metre and FAI 18 metre Class, 18 metre single-seat Glider aircraft, gliders and motor gliders produced by DG Flugzeugbau GmbH, Glaser-Dirks since 1993 and by DG Flugzeugbau GmbH after 1997. It is the successor to the Glaser-Dirks DG-400, DG-400 and the Glaser-Dirks DG-600, DG-600 models. Design and development The DG-800 was planned primarily as a powered self-launching sailplane. In the meantime it has spawned many variants, differentiated by the type of powerplant (Rotax, MidWest AE series, Midwest or Solo 2625, Solo), the span extensions (15 metre, 18 metre, both in variants with or without winglets), maximum takeoff weight, maximum allowed take-off mass, etc. The newest model is the DG-808C, a self launching sailplane with a Solo 2625 engine and the new designed "DEI-NT" Engine Control System. There are also unpowered variants, the DG-800S and DG-808S, aimed at gliding competition, competition flying. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or Scavenging (automotive), scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringe ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect. Some unusual land ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Europa Aircraft
Europa Aircraft is a British kitplane manufacturer that produces the Europa XS. The company was established to produce a small kit-built low-wing aircraft for personal use within Europe, with these design goals: high speed, low cost, able to be built and stored at home, easily transportable, using Mogas fuel, able to be rigged for flight in under five minutes, carrying two people in comfort, providing sufficient baggage for extended touring. Apart from "low cost", these design parameters were largely met. History The original Europa, (the "Classic"), was designed by Ivan Shaw (born 1945) and the prototype, G-YURO, first flew in February 1992. Production of kit components was established at the company's factory in Kirkbymoorside, North Yorkshire. In the early 1990s the company won a £100,000 grant from the UK Department of Trade and Industry in recognition of its technical achievements. Europa Aircraft has grown to be one of the most successful British kit plane supplie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-hangar
{{Refimprove, date=January 2011 A Tee hangar is a type of enclosed structure designed to hold aircraft in protective storage, and their shape takes advantage of the shape of most general aviation aircraft where the main wings are longer than the horizontal stabilizer. This type of hangar is also known as Tee-hangar, T hangar or T-hangar. Typically constructed of metal, they are primarily used for private aircraft at general aviation airport An airport is an aerodrome with extended facilities, mostly for commercial Aviation, air transport. They usually consist of a landing area, which comprises an aerially accessible open space including at least one operationally active surf ...s because they are more economical than rectangular hangars. There are two types of Tee hangars: ''standard'' (sometimes called ''stacked'') and ''nested''. Standard ''Tee hangars'' provide additional storage area and can use rolling doors. In the diagram, the odd-shaped areas at the end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Light Aircraft
A light aircraft is an aircraft that has a Maximum Takeoff Weight, maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308. Aviation Supplies & Academics, 1997. Light aircraft are used as utility aircraft commercially for small-scale passenger and cargo aircraft, freight transport; for sightseeing, photography, cropdusting, and other so-called aerial work roles of civil aviation; for the personal-use aspect of general aviation; and in certain aspects of military aviation. Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft Super King Air, Beechcraft B200 Super King Air. Uses Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as regional airline, "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliding
Gliding is a recreational activity and competitive air sports, air sport in which pilots fly glider aircraft, unpowered aircraft known as Glider (sailplane), 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, 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 course ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose gliding flight, free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by Motor glider, self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit lift (soaring), meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such a ...
