Wing Loading
In aerodynamics, wing loading is the total weight of an aircraft or flying animal divided by the area of its wing. The stalling speed, takeoff speed and landing speed of an aircraft are partly determined by its wing loading. The faster an aircraft flies, the more its lift (force), lift is changed by a change in angle of attack, so a smaller wing is less adversely affected by Wind gust, vertical gusts. Consequently, faster aircraft generally have higher wing loadings than slower aircraft in order to avoid excessive response to vertical gusts. 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 aircraft with a large wing area relative to its mass (i.e., low wing loading) will have a lower stalling speed. ...

Monarch In May
A monarch () is a head of stateWebster's II New College Dictionary. "Monarch". Houghton Mifflin. Boston. 2001. p. 707. Life tenure, 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 Sovereign state, state, or others may wield that power on behalf of the monarch. Usually, a monarch either personally inheritance, inherits the lawful right to exercise the state's sovereign rights (often referred to as ''the throne'' or ''the Crown, the crown'') or is elective monarchy, selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may self-proclaimed monarchy, proclaim oneself monarch, which may be backed and Legitimacy (political), 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 requisi ...

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 belligerents, Germany and Japan on the one side and United Kingdom, 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 wikt:streamlined, 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 performa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermarine Spitfire
The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and other Allies of World War II, Allied countries before, during, and after World War II. It was the only British fighter produced continuously throughout the war. The Spitfire remains popular among enthusiasts. Around List of surviving Supermarine Spitfires, 70 remain airworthy, and many more are static exhibits in aviation museums throughout the world. The Spitfire was a short-range, high-performance interceptor aircraft designed by R. J. Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell modified the Spitfire's distinctive elliptical wing (designed by Beverley Shenstone) with innovative sunken rivets to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary fighter aircraft, including the Hawker Hurricane. Mitchell continued to refine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Lycoming O-540 engines; Cessna too had improved its 310 with two Continental IO-470 D, producing . 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, the 55, was powered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Aviation
General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations except for 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, most of which is accomplished with light aircraft. 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 adver ...

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 very low 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 either ...

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 shor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fédération Aéronautique Internationale
The World Air Sports Federation (; FAI) is the world governing body for air sports, and also stewards definitions regarding human spaceflight. It was founded on 14 October 1905, and is headquartered in Lausanne, Switzerland. It maintains world records for aeronautical activities, including ballooning, aeromodeling, and unmanned aerial vehicles (drones), as well as flights into space. History The FAI was founded at a conference held in Paris 12–14 October 1905, which was organized following a resolution passed by the Olympic Congress held in Brussels on 10 June 1905 calling for the creation of an Association "to regulate the sport of flying, ... the various aviation meetings and advance the science and sport of Aeronautics." The conference was attended by representatives from 8 countries: Belgium (, founded 1901), France ( Aéro-Club de France, 1898), Germany ( aka "German Airship League", founded 1902), Great Britain (Royal Aero Club, 1901), Italy (, 1904), Spain (, 19 ...
