Rotorcraft Flight Record Holders
A rotary-wing aircraft, rotorwing aircraft or rotorcraft is a heavier-than-air aircraft with rotary wings that spin around a vertical mast to generate lift. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that rotorcraft "means a heavier-than-air aircraft that depends principally for its support in flight on the lift generated by one or more rotors." The assembly of several rotor blades mounted on a single mast is referred to as a rotor. The International Civil Aviation Organization (ICAO) defines a rotorcraft as "supported in flight by the reactions of the air on one or more rotors". Rotorcraft generally include aircraft where one or more rotors provide lift throughout the entire flight, such as helicopters, gyroplanes, autogyros, and gyrodynes Compound rotorcraft augment the rotor with additional thrust engines, propellers, or static lifting surfaces. Some types, such as helicopters, are capable of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transverse Rotors
A transverse-rotor aircraft is an aircraft with two large Horizontal plane, horizontal helicopter rotor, rotor assemblies mounted side by side. Single-rotor helicopters (unicopters) need an additional tail rotor or NOTAR, tail exhaust to neutralize the reaction (physics), reactional angular momentum produced by the main rotor. Transverse rotor helicopters, however, use counter-rotating rotors, with each cancelling out the other's torque. Counter-rotating rotor blades also won't collide with and destroy each other if they flex into the other rotor's pathway. In addition, transverse rotor configuration has the advantage of higher payload with shorter airfoil, blades, since there are two sets working to provide lift (force), lift. Also, all of the power from the engines can be used for lift, whereas a single-rotor helicopter must divert part of its engine power to generate tail thrust. Transverse rotor design with rotatable nacelles are known as tiltrotors while designs where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandem Rotors
A tandem-rotor aircraft is an aircraft with two large helicopter rotor assemblies mounted one in front of the other in the horizontal plane. This configuration is mainly used for large cargo helicopters. Such aircraft are often informally referred to as "Chinooks," after the CH-47 Chinook, one of the first widely adopted heavy-lift helicopters with a tandem-rotor configuration. Design Single-rotor helicopters need a mechanism to neutralize the yawing movement produced by the single large rotor. This is commonly accomplished by a tail rotor, coaxial rotors, and the NOTAR systems. Tandem-rotor helicopters, however, use counter-rotating rotors, with each cancelling out the other's torque. Therefore, all of the power from the engines can be used for lift, whereas a single-rotor helicopter uses some of the engine power to counter the torque. An alternative is to mount two rotors in a coaxial configuration. The first successful tandem-rotor helicopter was built by Nicolas Flo ...

Monocopter
A monocopter or gyropter is a rotorcraft that uses a single rotating blade. The concept is similar to the whirling helicopter seeds that fall from some trees. The name gyropter is sometimes applied to monocopters in which the entire aircraft rotates about its center of mass as it flies. The name "monocopter" has also been applied to the personal jet pack constructed by Andreas Petzoldt. History Papin-Rouilly The ''Gyroptère'' was designed in 1913–1914 by Alphonse Papin and Didier Rouilly in France, inspired by a maple seed. Papin and Rouilly obtained French patents 440,593 and 440,594 for their invention, and later obtained US patent 1,133,660 in 1915. The Gyroptère was characterized in the contemporary French journal '' La Nature'' in 1914 as "" (a giant boomerang). Following demonstrations of small rocket-powered models, the Army ordered a manned prototype in 1913. Papin and Rouilly's "Gyroptère" weighed including the float on which it was mounted. It had a single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tipjet
A tip jet is a jet nozzle at the tip of some helicopter rotor blades, used to spin the rotor, much like a Catherine wheel firework. Tip jets replace the normal shaft drive and have the advantage of placing no torque on the airframe, thus not requiring the presence of a tail rotor. Some simple monocopters are composed of nothing but a single blade with a tip rocket. Tip jets can use compressed air, provided by a separate engine, to create jet thrust. Other types use a system that functions similarly to the afterburner (reheat) on a conventional jet engine, except that instead of reheating a gas jet, they serve as the primary heater, creating greater thrust than the flow of pre-compressed air alone; the best description of this is ''thrust augmentation''. Other designs includes ramjets or even a complete turbojet engine. Some, known as ''rocket-on-rotor'' systems, involve placing rockets on the tips of the rotor blades that are fueled from a tank. If the helicopter's engine fail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blade
A blade is the Sharpness (cutting), sharp, cutting portion of a tool, weapon, or machine, specifically designed to puncture, chop, slice, or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are intended to cut. This includes early examples made from flaked stones like flint or obsidian, evolving through the ages into metal forms like copper, bronze, and iron, and culminating in modern versions made from steel or ceramics. Serving as one of humanity's oldest tools, blades continue to have wide-ranging applications, including in combat, cooking, and various other everyday and specialized tasks. Blades function by concentrating force at the cutting edge. Design variations, such as serrated edges found on bread knives and saws, serve to enhance this force concentration, adapting blades for specific functions and materials. Blades thus hold a significant place both historically and in contemporary society, reflecting an evolution i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Juan De La Cierva
Juan de la Cierva y Codorníu, 1st Count of la Cierva (; 21 September 1895 – 9 December 1936), was a Spanish civil engineer, pilot and a self-taught aeronautical engineer. His most famous accomplishment was the invention in 1920 of a rotorcraft called ''Autogiro'',''Aero Digest'', Feb 1939, p. 27 a single-rotor type of aircraft that came to be called autogyro in the English language. In 1923, after four years of experimentation, De la Cierva developed the articulated rotor, which resulted in the world's first successful flight of a stable rotary-wing aircraft, with his C.4 prototype. Early life Juan de la Cierva was born to a wealthy, aristocratic Spanish family, and for a time his father was the war minister. At the age of eight he was spending his pocket money with his friends on experiments with gliders in one of his father's work sheds. In their teens they constructed an aeroplane from the wreckage they had bought from a French aviator who had crashed the plane. The fina ...
