Barrel Roll
A barrel roll is an aerial maneuver in which an airplane makes a complete rotation on both its longitudinal and lateral axes, causing it to follow a helix, helical path, approximately maintaining its original direction. It is sometimes described as a "combination of a loop and a Aircraft principal axes#Longitudinal axis (roll), roll". The g-force is kept positive (but not constant) on the object throughout the maneuver, commonly between 2 and 3''g'', and no less than 0.5''g''. The barrel roll is commonly confused with an aileron roll. Etymology The barrel roll is so named because an aircraft executing this maneuver looks as though it were flying with its wheels running around the inside wall of a cylinder, or an imaginary barrel lying on its side. A more common modern visualization is to imagine an airplane trying to fly in a horizontal corkscrew around the line of the direction of travel. Although the maneuver predates the name, the term was first used in 1917, gaining populari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrel Roll Diagram Side View
A barrel or cask is a hollow cylindrical container with a bulging center, longer than it is wide. They are traditionally made of wooden stave (wood), staves and bound by wooden or metal hoops. The word vat is often used for large containers for liquids, usually alcoholic beverages; a small barrel or cask is known as a keg. Barrels have a variety of uses, including storage of liquids such as water, oil, and alcohol. They are also employed to hold maturing beverages such as wine, Cognac (brandy), cognac, Armagnac (drink), armagnac, sherry, port wine, port, whiskey, beer, arrack, and sake. Other commodities once stored in wooden casks include gunpowder, Salt-cured meat, meat, fish, paint, honey, nails, and tallow. Modern wooden barrels for wine-making are made of English oak (''Quercus robur''), white Oak (wine), oak (''Quercus petraea''), American white oak (''Quercus alba''), more exotic is mizunara oak (''Quercus crispula''), and recently Oregon oak (''Quercus garryana'') ...

Boeing 367-80
The Boeing 367-80, also known as the Dash 80, is a retired American four-engined prototype jet aircraft by Boeing to demonstrate the advantages of jet propulsion for commercial aviation. It served as basis for the design of the KC-135 tanker and the 707 airliner. The Boeing 367-80 first flew in 1954, less than two years from project launch. Its US$16 million cost (equivalent to $ million today) was an enormous risk for Boeing, which at the time had no committed customers. Only one example was built, which has been retired and now preserved and is on public display at the Smithsonian's National Air and Space Museum's Udvar-Hazy Center in Virginia. Design and development By the late 1940s, two developments encouraged Boeing to begin considering building a passenger jet. The first was the maiden flight of Boeing’s B-47 Stratojet bomber in 1947. The second was the maiden flight of the world's first jet airliner, the de Havilland Comet in 1949. Boeing President Bill Allen le ...

Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes and canards) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or afterend. Often rudders are shaped to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics. H ...

Lift Vector
When a fluid flows around an object, the fluid exerts a force on the object. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the force parallel to the flow direction. Lift conventionally acts in an upward direction in order to counter the force of gravity, but it is defined to act perpendicular to the flow and therefore can act in any direction. If the surrounding fluid is air, the force is called an aerodynamic force. In water or any other liquid, it is called a hydrodynamic force. Dynamic lift is distinguished from other kinds of lift in fluids. Aerostatic lift or buoyancy, in which an internal fluid is lighter than the surrounding fluid, does not require movement and is used by balloons, blimps, dirigibles, boats, and submarines. Planing lift, in which only the lower portion of the body is immersed in a liquid flow, is used by motorboats, surfboards, windsurfers, sailboat ...

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called rolling or banking. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Boul ...

Avro Vulcan
The Avro Vulcan (later Hawker Siddeley Vulcan from July 1963) was a jet-powered, tailless, delta-wing, high-altitude, strategic bomber, which was operated by the Royal Air Force (RAF) from 1956 until 1984. Aircraft manufacturer A.V. Roe and Company ( Avro) designed the Vulcan in response to Specification B.35/46. Of the three V bombers produced, the Vulcan was considered the most technically advanced, and therefore the riskiest option. Several reduced-scale aircraft, designated Avro 707s, were produced to test and refine the delta-wing design principles. The Vulcan B.1 was first delivered to the RAF in 1956; deliveries of the improved Vulcan B.2 started in 1960. The B.2 featured more powerful engines, a larger wing, an improved electrical system, and electronic countermeasures, and many were modified to accept the Blue Steel missile. As a part of the V-force, the Vulcan was the backbone of the United Kingdom's airborne nuclear deterrent during much of the Cold War. A ...

Roland Falk
Wing Commander Roland "Roly" John Falk OBE AFC* (1915 - 1985) was a British test pilot noted for being at the controls on the maiden flight of the British V bomber, the Avro Vulcan. Falk typically flew dressed in pin stripe suit and tie. Early life Falk was born in London in 1915, the second son of Diana Gwendoline Edith Cecil (née Stracey) and Oswald Toynbee Falk, and he was educated at Stowe School and the de Havilland Technical School. After gaining his pilot's licence he flew in both the Abyssinian War and the Spanish Civil War for the press. In 1937 he flew a newspaper service from London to Paris and then joined the Air Registration Board as a test pilot. Wartime service Falk had been a member of the Reserve of Air Force Officers since 1935 and at the start of the Second World War in 1939 he joined the Royal Air Force. By 1943 he was chief test pilot at the Royal Aircraft Establishment Farnborough. At Farnborough he flew and tested captured German aircraft as well a ...

Avro
Avro (an initialism of the founder's name) was a British aircraft manufacturer. Its designs include the Avro 504, used as a trainer in the First World War, the Avro Lancaster, one of the pre-eminent bombers of the Second World War, and the delta wing Avro Vulcan, a stalwart of the Cold War. Avro was founded in 1910 by Alliott Verdon Roe at the Brownsfield Mill on Great Ancoats Street in Manchester. The company remained based primarily in Lancashire throughout its 53 years of existence, with key development and manufacturing sites in Alexandra Park, Chadderton, Trafford Park, and Woodford, Greater Manchester. The company was merged into Hawker Siddeley Aviation in 1963, although the Avro name has been used for some aircraft since then. History Early history One of the world's first aircraft builders, A.V. Roe and Company was established on 1 January 1910 at Brownsfield Mill, Great Ancoats Street, Manchester, by Alliott Verdon Roe and his brother Humphrey Verdon Roe ...
