Stagger (aviation)
In aviation Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as h ..., stagger is the relative horizontal fore-aft positioning of stacked wings in a biplane, triplane, or multiplane. An aircraft is said to have ''positive stagger'', or simply ''stagger'', when the upper wing is positioned forward of the lower (bottom) wing,NACA technical report No.310 ''Wind Tunnel Pressure Distribution Tests on a Series of Biplane Wing Models'' (July 1929), p.17.

Sopwith Dolphin
The Sopwith 5F.1 Dolphin was a British fighter aircraft manufactured by the Sopwith Aviation Company. It was used by the Royal Flying Corps and its successor, the Royal Air Force, during the First World War. The Dolphin entered service on the Western Front (World War I), Western Front in early 1918 and proved to be a formidable fighter. The aircraft was not retained in the postwar inventory and was retired shortly after the war. Design and development In early 1917, the Sopwith chief engineer, Herbert Smith, began designing a new fighter (internal Sopwith designation 5F.1) powered by the geared Hispano-Suiza 8B.Franks 2002, p. 7. The Dolphin was a two-bay, single-seat biplane, with the upper wings attached to an open steel cabane strut, cabane frame above the cockpit. To maintain the correct centre of gravity, the lower wings were positioned forward of the upper wings, creating the Dolphin's distinctive negative wing Stagger (aeronautics), stagger.Cooksley 1991, p. 34.

Flight Dynamics
Flight dynamics in aviation and spacecraft, is the study of the performance, stability, and control of vehicles flight, flying through the air or in outer space. It is concerned with how forces acting on the vehicle determine its velocity and attitude with respect to time. For a fixed-wing aircraft, its changing Orientation (geometry), orientation with respect to the local air flow is represented by two critical angles, the angle of attack of the wing ("alpha") and the angle of attack of the vertical tail, known as the slip (aerodynamics), sideslip angle ("beta"). A sideslip angle will arise if an aircraft yaws about its centre of gravity and if the aircraft sideslips bodily, i.e. the centre of gravity moves sideways.Flightwise - Volume 2 - Aircraft Stability And Control, Chris Carpenter 1997, Airlife Publishing Ltd., , p.145 These angles are important because they are the principal source of changes in the aerodynamic forces and moments applied to the aircraft.

Center Of Pressure (fluid Mechanics)
In fluid mechanics, the center of pressure is the point on a body where a single force acting at that point can represent the total effect of the pressure field acting on the body. The total force vector acting at the center of pressure is the surface integral of the pressure vector field across the surface of the body. The resultant force and center of pressure location produce an equivalent force and moment on the body as the original pressure field. Pressure fields occur in both static and dynamic fluid mechanics. Specification of the center of pressure, the reference point from which the center of pressure is referenced, and the associated force vector allows the moment generated about any point to be computed by a translation from the reference point to the desired new point. It is common for the center of pressure to be located on the body, but in fluid flows it is possible for the pressure field to exert a moment on the body of such magnitude that the center of press ...

Vickers Vildebeest
The Vickers Vildebeest and the similar Vickers Vincent are single-engined British biplanes designed and built by Vickers and used as light bombers, torpedo bombers and in army cooperation roles. First flown in 1928, they remained in service at the start of the Second World War, with the last Vildebeests flying against Japanese forces over Singapore and Java in 1942. Design and development Vildebeest Designed against Air Ministry Specification 24/25 for the Royal Air Force (RAF), for a land-based torpedo bomber to replace the Hawker Horsley, the prototype Vildebeest, an all-metal fuselage aircraft with single-bay unstaggered fabric-covered wings and tail, was first flown in April 1928 as the Vickers Type 132, powered by a Bristol Jupiter VIII radial engine.Mason 1994, p. 200. After initial evaluation, the Vildebeest was shortlisted for comparison with the Blackburn Beagle and Handley Page Hare. As the Jupiter VIII was prone to vibration, a second prototype, the Vickers Ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sopwith Cuckoo
The Sopwith T.1 Cuckoo was a British biplane torpedo bomber used by the Royal Naval Air Service (RNAS), and its successor organization, the Royal Air Force (RAF). The T.1 was the first landplane specifically designed for carrier operations, but it was completed too late for service in the First World War. After the Armistice, the T.1 was named the Cuckoo.Davis 1999, p. 123. Design and development In October 1916, Commodore Murray Sueter, the Air Department's Superintendent of Aircraft Construction, solicited Sopwith for a single-seat aircraft capable of carrying a 1,000 lb torpedo and sufficient fuel to provide an endurance of four hours. The resulting aircraft, designated T.1 by Sopwith,Robertson 1970, p. 125. was a large, three-bay biplane. Because the T.1 was designed to operate from carrier decks, its wings were hinged to fold backwards. The T.1 could take off from a carrier deck in four seconds, but it was not capable of making a carrier landing and no arresting gea ...

Beech Model 17 Staggerwing
The Beechcraft Model 17 Staggerwing is an American biplane with an atypical negative wing stagger (the lower wing is farther forward than the upper wing). It first flew in 1932, and was sold on the civilian market, being used for transport and air racing. During World War II, it was used by allied forces, and after the war continued in civilian production until 1949, with 785 having been produced. Development In 1932, Walter H. Beech, formerly head of the aircraft manufacturer Travel Air, left Curtiss-Wright, which had purchased Travel Air in 1929, to set up a new company, Beech Aircraft Corporation, based in Wichita, Kansas. Beech took the airplane designer Ted A. Wells from Curtiss-Wright, and the first project of the new company was the Model 17, a fast biplane with an enclosed cabin designed to meet the needs of business executives. It was based on a design drafted by Wells while at Curtiss-Wright, but rejected by the Curtiss-Wright board. The Beechcraft Model 17, pop ...

Boeing-Stearman Model 75
The Stearman (Boeing) Model 75 is an American biplane formerly used as a military Trainer (aircraft), trainer aircraft, of which at least 10,626 were built in the United States during the 1930s and 1940s. Stearman Aircraft became a subsidiary of Boeing in 1934. Widely known as the Stearman, Boeing Stearman, or Kaydet, it served as a primary trainer for the United States Army Air Forces, the United States Navy (as the NS and N2S), and with the Royal Canadian Air Force as the Kaydet throughout World War II. After the conflict was over, thousands of surplus aircraft were sold on the civilian market. In the immediate postwar years, they became popular as Aerial application, crop dusters and sports planes, and for aerobatics, aerobatic and wing walking use in air shows. Design and development In late 1933, Stearman engineers Mac Short, Harold W. Zipp, and J. Jack Clark took a 1931 Lloyd Stearman design, and added cantilever landing gear and adjustable elevator trim tabs, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Havilland Tiger Moth
The de Havilland DH.82 Tiger Moth is a 1930s British biplane designed by Geoffrey de Havilland and built by the de Havilland, de Havilland Aircraft Company. It was operated by the Royal Air Force (RAF) and other operators as a primary trainer (aircraft), trainer aircraft. In addition to the type's principal use for ''ab initio'' training, the World War II, Second World War had RAF Tiger Moths operating in other capacities, including Maritime patrol aircraft, maritime surveillance and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers. The Tiger Moth remained in service with the RAF until it was replaced by the de Havilland Canada DHC-1 Chipmunk, de Havilland Chipmunk during the early 1950s. Many of the military surplus aircraft subsequently entered into civilian operation. Many nations have used the Tiger Moth in both military and civilian applications, and it remains in widespread use as a recreational aircraft. It is s ...

Multiplane (aeronautics)
In aviation, a multiplane is a fixed-wing aircraft-configuration featuring multiple wing planes. The wing planes may be stacked one above another, or one behind another, or both in combination. Types having a small number of planes have specific names and are not usually described as multiplanes: * Biplane - two wings stacked one above the other * Triplane - three wings stacked one above another * Tandem wing - two main planes, one behind the other. The tandem triple or tandem triplet configuration has three lifting surfaces one behind another. While triplane, quadruplane and tandem designs are relatively uncommon, aircraft with more than four sets of wings rarely occur - none have proven successful. Quadruplanes The quadruplane configuration takes the triplane approach a step further, using efficient wings of high aspect ratio and stacking them to allow a compact and light weight design. During the pioneer years of aviation and World War I, a few designers sought these potentia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
