Aircraft
An aircraft is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or in a few cases the Powered lift, downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, Powered aircraft#Methods of propulsion, aircraft propulsion, usage and others. History Flying model craft and stories of ...

Cessna 172S Skyhawk ‘G-JMKE’ (45077563364)
Cessna () is an American brand of general aviation aircraft owned by Textron Aviation since 2014, headquartered in Wichita, Kansas. Originally, it was a brand of the Cessna Aircraft Company, an American general aviation aircraft manufacturing corporation also headquartered in Wichita. The company produced small, Reciprocating engine, piston-powered aircraft, as well as business jets. For much of the mid-to-late 20th century, Cessna was one of the highest-volume and most diverse producers of general aviation aircraft in the world. It was founded in 1927 by Clyde Cessna and Victor Roos and was purchased by General Dynamics in 1985, then by Textron, Textron, Inc. in 1992. In March 2014, when Textron purchased the Beechcraft and Hawker Aircraft corporations, Cessna ceased operations as a subsidiary company and joined the others as one of the three distinct brands produced by Textron Aviation. Throughout its history, and especially in the years following World War II, Cessna became b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...

Aircrew
Aircrew, also called flight crew, are personnel who operate an aircraft while in flight. The composition of a flight's crew depends on the type of aircraft, plus the flight's duration and purpose. Commercial aviation Flight deck positions In commercial aviation, the aircrew are called ''flight crew''. Some flight crew position names are derived from nautical terms and indicate a rank or command structure similar to that on ocean-going vessels, allowing for quick executive decision making during normal operations or emergency situations. Historical flightdeck positions include: * Captain, the pilot highest-ranking member or members of a flight crew. * First officer (FO, also called a co-pilot), another pilot who is normally seated to the right of the captain. (On helicopters, an FO is normally seated to the left of the captain, who occupies the right-hand seat).Smith, PatrickPatrick Smith's Ask The Pilot: When a Pilot Dies in Flight AskThePilot.com website, 2013, whic ...

USS Akron (ZRS-4) In Flight Over Manhattan, Circa 1931-1933
USS ''Akron'' (ZRS-4) was a helium-filled rigid airship of the U.S. Navy, the lead ship of her class, which operated between September 1931 and April 1933. It was the world's first purpose-built flying aircraft carrier, carrying F9C Sparrowhawk fighter planes, which could be launched and recovered while it was in flight. With an overall length of , ''Akron'' and her sister ship were among the largest flying objects ever built. Although LZ 129 ''Hindenburg'' and LZ 130 ''Graf Zeppelin II'' were some longer and slightly more voluminous, the two German airships were filled with hydrogen, and so the two US Navy craft still hold the world record for the largest helium-filled airships. ''Akron'' was destroyed in a thunderstorm off the coast of New Jersey on the morning of 4 April 1933, killing 73 of the 76 crewmen and passengers. The accident involved the greatest loss of life in any airship crash. Technical description The airship's skeleton was built of the new lightweight ...

Colorado Springs Hot Air Balloon Competition
Colorado (, other variants) is a state in the Mountain West subregion of the Western United States. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth most extensive and 21st most populous U.S. state. The 2020 United States census enumerated the population of Colorado at 5,773,714, an increase of 14.80% since the 2010 United States census. The region has been inhabited by Native Americans and their ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. "''Colorado''" is the Spanish adjective meaning "ruddy", the color of the Fountain Formation outcroppings found up and down the Front Range of the Rocky Mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulysses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Age
The Jet Age is a period in the history of aviation defined by the advent of aircraft powered by jet turbine engines, and by the social change this brought about. Jet airliners were able to fly much higher, faster, and farther than older pistonpowered propliners, making transcontinental and intercontinental travel considerably faster and easier: for example, aircraft leaving North America and crossing the Atlantic Ocean (and later, the Pacific Ocean) could now fly to their destinations non-stop, making much of the world accessible within a single day's travel for the first time. Since large jetliners could also carry more passengers than piston-powered airliners, air fares also declined (relative to inflation), so people from a greater range of socioeconomic classes could afford to travel outside their own countries. Besides the pure jet, the turbine-driven propeller engines offered improvements of the piston engine delivering a smoother ride and better fuel efficiency. One ex ...

Post-war
In Western usage, the phrase post-war era (or postwar era) usually refers to the time since the end of World War II. More broadly, a post-war period (or postwar period) is the interval immediately following the end of a war. A post-war period can become an interwar period or interbellum, when a war between the same parties resumes at a later date (such as the period between World War I and World War II). By contrast, a post-war period marks the cessation of armed conflict entirely. Post–World War II Chronology of the post–World War II era The term "post-war" can have different meanings in different countries and refer to a period determined by local considerations based on the effect of the war there. Some examples of post-war events are (in chronological order) ;The Cold War (1947–1991) The Cold War was a geopolitical conflict between the capitalist and liberal democratic United States of America, the authoritarian and Communist Marxist–Leninist Union of Soviet Soc ...

Air Warfare Of World War II
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in E ...

Aviation Between The World Wars
Sometimes dubbed the Golden Age of Aviation, the period in the history of aviation between the end of World War I (1918) and the beginning of World War II (1939) was characterised by a progressive change from the slow wood-and-fabric biplanes of World War I to fast, streamlined metal monoplanes, creating a revolution in both commercial and military aviation. By the outbreak of World War II in 1939 the biplane was all but obsolete. This revolution was made possible by the continuing development of lightweight aero engines of increasing power. The jet engine also began development during the 1930s but would not see operational use until later. During this period civil aviation became widespread and many daring and dramatic feats took place such as round-the-world flights, air races and barnstorming displays. Many commercial airlines were started during this period. Long-distance flights for the luxury traveller became possible for the first time; the early services used airsh ...

Aviation In World War I
World War I was the first major conflict involving the large-scale use of aircraft. Tethered observation balloons had already been employed in several wars, and would be used extensively for artillery spotting. Germany employed Zeppelins for reconnaissance over the North Sea and Baltic and also for strategic bombing raids over Britain and the Eastern Front. Aeroplanes were just coming into military use at the outset of the war. Initially, they were used mostly for reconnaissance. Pilots and engineers learned from experience, leading to the development of many specialized types, including fighters, bombers, and trench strafers. Ace fighter pilots were portrayed as modern knights, and many became popular heroes. The war also saw the appointment of high-ranking officers to direct the belligerent nations' air war efforts. While the impact of aircraft on the course of the war was mainly tactical rather than strategic, most important being direct cooperation with ground forces ...

Early Flying Machines
Early flying machines include all forms of aircraft studied or constructed before the development of the modern aeroplane by 1910. The story of modern flight begins more than a century before the first successful manned aeroplane, and the earliest aircraft thousands of years before. Primitive beginnings Legends Some ancient mythologies feature legends of men using flying devices. One of the earliest known is the Greek legend of Daedalus; in Ovid's version, Daedalus fastens feathers together with thread and wax to mimic the wings of a bird. Other ancient legends include the Indian Vimana flying palace or chariot, the biblical Ezekiel's Chariot, the Irish ''roth rámach'' built by blind druid Mug Ruith and Simon Magus, various stories about magic carpets, and the mythical British King Bladud, who conjured up flying wings. The Flying Throne of Kay Kāvus was a legendary eagle-propelled craft built by the mythical Shah of Persia, Kay Kāvus, used for flying him all the way ...

World Wars
A world war is an international conflict which involves all or most of the world's major powers. Conventionally, the term is reserved for two major international conflicts that occurred during the first half of the 20th century, World WarI (1914–1918) and World WarII (1939–1945), although historians have also described other global conflicts as world wars, such as the Seven Years' War and the Cold War. Etymology The ''Oxford English Dictionary'' cited the first known usage in the English language to a Scottish newspaper, ''The People's Journal'', in 1848: "A war among the great powers is now necessarily a world-war." The term "world war" is used by Karl Marx and his associate, Friedrich Engels, in a series of articles published around 1850 called ''The Class Struggles in France''. Rasmus B. Anderson in 1889 described an episode in Teutonic mythology as a "world war" (Swedish: ''världskrig''), justifying this description by a line in an Old Norse epic poem, "Völuspá: fo ...
