Spinner (aircraft)
A spinner is an aircraft component, a streamlined fairing fitted over a propeller hub or at the centre of a turbofan engine. Spinners both make the aircraft overall more streamlined, thereby reducing aerodynamic drag, and also smooth the airflow so that it enters the air intakes more efficiently. Spinners also fulfill an aesthetic role on some aircraft designs.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 480. Aviation Supplies & Academics, 1997. Bingelis, Tony: ''Bingelis on Engines'', pages 196-210. Experimental Aircraft Association Aviation Foundation, 1995. Bingelis, Tony: ''Firewall Forward'', pages 269-273. Experimental Aircraft Association Aviation Foundation, 1992. Piston engine spinners Piston-powered aircraft often have spinners of one of two basic designs. The ''large spinner'' fits over the propeller, while the smaller ''skull cap'' style is directly attached to the propeller and just covers the propeller mounting bolts. The spinner may be co ...

Mustang Spinner (253798327)
The mustang is a free-roaming horse of the Western United States, descended from horses brought to the Americas by the Spanish. Mustangs are often referred to as wild horses, but because they are descended from once-domesticated animals, they are actually feral horses. The original mustangs were Colonial Spanish horses, but many other breeds and types of horses contributed to the modern mustang, now resulting in varying phenotypes. Some free-roaming horses are relatively unchanged from the original Spanish stock, most strongly represented in the most isolated populations. In 1971, the United States Congress recognized that "wild free-roaming horses and burros are living symbols of the historic and pioneer spirit of the West, which continue to contribute to the diversity of life forms within the Nation and enrich the lives of the American people". The free-roaming horse population is managed and protected by the U.S. Bureau of Land Management (BLM). Controversy surrounds the ...

Engine Cowling
A cowling is the removable covering of a vehicle's engine, most often found on automobiles, motorcycles, airplanes, and on outboard boat motors. On airplanes, cowlings are used to reduce drag and to cool the engine. On boats, cowlings are a cover for an outboard motor. In addition to protecting the engine, outboard motor cowlings need to admit air while keeping water out of the air intake. Etymology "Cowling" comes from "cowl", which originated from Middle English coule, from Old English cūle, from earlier cugele (“hood, cowl”). This, in turn, came from Ecclesiastical Latin cuculla (“monk's cowl”), from Latin cucullus (“hood”), of uncertain origin. In aviation In aviation, a cowling may be used for drag reduction or engine cooling by directing airflow. Examples in aviation include the NACA cowling and Townend ring. On an airplane, the cowling may also cover part of the fuselage, the nacelles, the engine mount and part of the cockpit.Aviation Machinist's Mates' Manua ...

Morane-Saulnier N
The Morane-Saulnier N, also known as the Morane-Saulnier Type N, was a French monoplane fighter aircraft of the First World War. Designed and manufactured by Morane-Saulnier, the Type N entered service in April 1915 with the ''Aéronautique Militaire'' designated as the MoS-5 C1. It also equipped four squadrons of the Royal Flying Corps, in which it was nicknamed the Bullet, and was operated in limited numbers by the 19th Squadron of the Imperial Russian Air Force. Description While the Type N was a clean, streamlined aircraft, it was not easy to fly due to a combination of stiff lateral control caused by using wing warping instead of ailerons, sensitive pitch and yaw controls caused by using an all flying tail, and very high landing speed for the period. The Type N mounted a single unsynchronized forward-firing 7.9 mm Hotchkiss machine gun which used the deflector wedges first used on the Morane-Saulnier Type L, in order to fire through the propeller arc. The later I and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Rotary Engine
The rotary engine is an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration. The engine's crankshaft remained stationary in operation, while the entire crankcase and its attached cylinders rotated around it as a unit. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles. This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. It has been described as "a very efficient solution to the problems of power output, weight, and reliability". By the early 1920s, the inherent limitations of this type of engine had rendered it obsolete. Description Distinction between "rotary" and "radial" engines A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional ra ...

Aviation In The Pioneer Era
The pioneer era of aviation was the period of aviation history between the first successful powered flight, generally accepted to have been made by the Wright Brothers on 17 December 1903, and the outbreak of the First World War in August 1914. Once the principles of powered controlled flight had been established there was a period in which many different aircraft configurations were experimented with. By 1914 the tractor configuration biplane had become the most popular form of aircraft design, and would remain so until the end of the 1920s. The development of the internal combustion engine—primarily from their use in early automobiles even before the start of the 20th century—which enabled successful heavier-than-air flight also produced rapid advances in lighter-than-air flight, particularly in Germany where the Zeppelin company rapidly became the world leader in the field of airship construction. During this period aviation passed from being seen as the preserve of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental under FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on most of the maintenance, repairs, and inspections themsel ...

Aircraft Fairing
An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag.Crane, Dale: ''Dictionary of Aeronautical Terms, Third Edition'', page 206. Aviation Supplies & Academics Inc, Newcastle Washington, 1997. These structures are covers for gaps and spaces between parts of an aircraft to reduce form drag and interference drag, and to improve appearance.Bingelis, Tony: ''The Sportplane Builder'', pages 261-265. Experimental Aircraft Association Aviation Foundation, 1979. Types On aircraft, fairings are commonly found on: ; Belly fairing : Also called a "ventral fairing", it is located on the underside of the fuselage between the main wings. It can also cover additional cargo storage or fuel tanks. ; Cockpit fairing : Also called a "cockpit pod", it protects the crew on ultralight trikes. Commonly made from fiberglass, it may also incorporate a windshield.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page C-17. Cybair ...

Fibreglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
