Wing Loading
In aerodynamics, wing loading is the total mass of an aircraft or flying animal divided by the area of its wing. The stalling speed of an aircraft in straight, level flight is partly determined by its wing loading. An aircraft or animal with a low wing loading has a larger wing area relative to its mass, as compared to one with a high wing loading. The faster an aircraft flies, the more lift can be produced by each unit of wing area, so a smaller wing can carry the same mass in level flight. Consequently, faster aircraft generally have higher wing loadings than slower aircraft. This increased wing loading also increases takeoff and landing distances. A higher wing loading also decreases maneuverability. The same constraints apply to winged biological organisms. Range of wing loadings Effect on performance Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monarch In May
A monarch is a head of stateWebster's II New College DictionarMonarch Houghton Mifflin. Boston. 2001. p. 707. for life or until abdication, and therefore the head of state of a monarchy. A monarch may exercise the highest authority and power in the state, or others may wield that power on behalf of the monarch. Usually a monarch either personally inherits the lawful right to exercise the state's sovereign rights (often referred to as ''the throne'' or ''the crown'') or is selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may proclaim themself monarch, which may be backed and legitimated through acclamation, right of conquest or a combination of means. If a young child is crowned the monarch, then a regent is often appointed to govern until the monarch reaches the requisite adult age to rule. Monarchs' actual powers vary from one monarchy to another and in different eras; on one extreme, they may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beechcraft Airliner
The Beechcraft Model 99 is a civilian aircraft produced by Beechcraft. It is also known as the Beech 99 Airliner and the Commuter 99. The 99 is a twin-engine, unpressurized, 15 to 17 passenger seat turboprop aircraft, derived from the earlier Beechcraft King Air and Queen Air. It uses the wings of the Queen Air, the engines and nacelles of the King Air, and sub-systems from both, with a specifically designed nose structure. Design and development Designed in the 1960s as a replacement for the Beechcraft Model 18, it first flew in July 1966. It received type certification on May 2, 1968, and 62 aircraft were delivered by the end of the year. In 1984, the Beechcraft 1900, a pressurized 19-passenger airplane, was introduced as the follow-on aircraft. Production ended in early 1987.

Aviation In World War II
During World War II, aviation firmly established itself as a critical component of modern warfare from the Battle of Britain in the early stages to the great aircraft carrier battles between American and Japanese Pacific fleets and the final delivery of nuclear weapons. The major combatants. Germany and Japan on the one side and Britain, the United States and the USSR on the other manufactured huge air forces which engaged in pitched battles both with each other and with the opposing ground forces. Bombing established itself as a major strategic force, and this was also the first war in which the aircraft carrier played a significant role. As with Aviation in World War I, military investment during World War II drove aviation forward in leaps and bounds. The streamlined cantilever monoplane quickly proves its worth in almost every role, although a few older biplanes remained in niche roles for much of the war. Engine power and aircraft performance increased steadily, with jet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermarine Spitfire
The Supermarine Spitfire is a British single-seat fighter aircraft used by the Royal Air Force and other Allied countries before, during, and after World War II. Many variants of the Spitfire were built, from the Mk 1 to the Rolls-Royce Griffon engined Mk 24 using several wing configurations and guns. It was the only British fighter produced continuously throughout the war. The Spitfire remains popular among enthusiasts; around 70 remain airworthy, and many more are static exhibits in aviation museums throughout the world. The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell developed the Spitfire's distinctive elliptical wing with innovative sunken rivets (designed by Beverley Shenstone) to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary figh ...

Beechcraft Baron
The Beechcraft Baron is a light twin-engined piston aircraft designed and produced by Beechcraft. The aircraft was introduced in 1961. A low-wing monoplane developed from the Travel Air, it remains in production. Design and development The direct predecessor of the Baron was the Beechcraft 95 Travel Air, which incorporated the fuselage of the Bonanza and the tail control surfaces of the T-34 Mentor military trainer. To create the new airplane, the Travel Air's tail was replaced with that of the Beechcraft Debonair, the engine nacelles were streamlined, six-cylinder engines were added, and the aircraft's name was changed. In 1960, the Piper Aztec was introduced, using two 250 hp Lycoming O-540 engines; Cessna too had improved its 310 with two Continental IO-470 D, producing 260 hp. Meanwhile, Beechcraft's Bonanza had been improved with a Continental IO-470-N. But the answer to competition was to make a true twin-engined variant of the Bonanza. The first model, th ...

General Aviation
General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations with the exception of commercial air transport or aerial work, which is defined as specialized aviation services for other purposes. However, for statistical purposes ICAO uses a definition of general aviation which includes aerial work. General aviation thus represents the "private transport" and recreational components of aviation. Definition The International Civil Aviation Organization (ICAO) defines civil aviation aircraft operations in three categories: General Aviation (GA), Aerial Work (AW) and Commercial Air Transport (CAT). Aerial work operations are separated from general aviation by ICAO by this definition. Aerial work is when an aircraft is used for specialized services such as agriculture, construction, photography, surveying, observation and patrol, search and rescue, and aerial advertisement. However, for statistical purposes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glider (sailplane)
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and eithe ...

Schleicher ASW 22
The ASW 22 is an Open Class glider built by Alexander Schleicher GmbH & Co which first flew in 1981. The 'W' in the designation indicates that this is a product of the German designer Gerhard Waibel. An ASW 22 broke the world 750 km triangle speed record in 1985 and ASW 22s have won first place in six World Gliding Championships. Design The ASW 22 is the successor to the ASW 17. It first flew as a 22-metre glider. The span was later increased to 25 metres for the ASW 22B with a modified inner wing section and flaperons similar to the ASW 20. It uses a Horstmann and Quast wing profile on the inner section with underwing tubes to collect high-pressure air which is then expelled through turbulator holes in the bottom wing skin ahead of the flap and aileron hinge line to prevent the separation of the laminar flow. The ASW 22 has a two-wheel retractable undercarriage. Variants ;ASW 22:Open Class high-performance sailplane; 22 or 24 metre span ;ASW 22M:First motorized self ...

Microlight
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is installed. The definition means that the aircraft has a slow landing speed and short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
