Edwards Rhomboidal
The Edwards Rhomboidal was an early British aircraft of extremely unorthodox configuration designed by E.W. Edwards. Design and development The Edwards Rhomboidal was an annular wing biplane with identical upper and lower surfaces consisting of four surfaces in a diamond arrangement, the aft wings being of three times the chord of the forward wings. It had been arrived at as a result of successful experiments with a rubber-driven model monoplane. The main structure of the aircraft was formed by a pair of triangular section wire-braced trusses arranged one above another, connected by five sets of paired struts. Each girder bore a pair of substantial flexibly mounted struts extending outwards, the wings being tensioned between the ends of the longitudinal girders and the outer ends of the struts by means of cables which formed the wing leading edges. The trailing edges were under less tension, the intention being that the wings would automatically deform to spread flight loads ...

Experimental Aircraft
An experimental aircraft is an aircraft intended for testing new aerospace technologies and design concepts. The term ''research aircraft'' or '' testbed aircraft'', by contrast, generally denotes aircraft modified to perform scientific studies, such as weather research or geophysical surveying, similar to a research vessel. United States The term "experimental aircraft" also has specific legal meaning in Australia, the United States and some other countries; usually used to refer to aircraft flown with an experimental certificate. In the United States, this also includes most 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, Kenn ..., many of which are based on conventional designs and hence are experimental only in name because of certain restrictions in operation.

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) 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 stabilizer and the ...

1910s British Experimental Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 '' Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Parthia * King Vologases IV of Parthia dies after a 44-year reign, and is succeeded by his son Vologases V. China * A coalition of Chinese warlords from the east of Hangu Pass launches a punitive campaign against the warlord Dong Zhuo, who seized control of the central government in 189, and held the figurehead Emperor Xian hostage.

Before leaving, Dong Zhuo orders his troops to loot the tombs of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humber (car)
Humber Limited was a British manufacturer of bicycles, motorcycles, and cars incorporated and listed on the stock exchange in 1887. It took the name "Humber & Co Limited" because of the high reputation of the products of one of the constituent businesses that had belonged to Thomas Humber. A financial reconstruction in 1899 transferred its business to Humber Limited. From an interest in motor vehicles beginning in 1896, the motor division became much more important than the cycle division and the cycle trade marks were sold to Raleigh in 1932. The motorcycles were withdrawn from sale during the depression of the 1930s. Humber is now a dormant marque for automobiles as well as cycles. Following their involvement in Humber through Hillman in 1928 the Rootes brothers acquired 60 per cent of Humber's ordinary capital, sufficient for a controlling interest. The two Rootes brothers joined the Humber board in 1932 and began to make Humber the holding company for vehicle manufacturing ...

Brooklands
Brooklands was a motor racing circuit and aerodrome built near Weybridge in Surrey, England, United Kingdom. It opened in 1907 and was the world's first purpose-built 'banked' motor racing circuit as well as one of Britain's first airfields, which also became Britain's largest aircraft manufacturing centre by 1918, producing military aircraft such as the Wellington and civil airliners like the Viscount and VC-10. The circuit hosted its last race in August 1939 and today part of it forms the Brooklands Museum, a major aviation and motoring museum, as well as a venue for vintage car, motorcycle and other transport-related events. History Brooklands motor circuit The Brooklands motor circuit was the brainchild of Hugh Fortescue Locke-King, and was the first purpose-built banked motor race circuit in the world. Following the Motor Car Act 1903, Britain was subject to a blanket speed limit on public roads: at a time when nearly 50% of the world's new cars were produce ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally air or water). On an aircraft 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 after end. Often rudders are shaped so as 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 be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical li ...

Leading Edge
The leading edge of an airfoil surface such as a wing is its foremost edge and is therefore the part which first meets the oncoming air.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305. Aviation Supplies & Academics, 1997. Characteristics Sweep Seen in plan the leading edge may be straight, curved, kinked or a combination of these. A straight leading edge may be swept or unswept, while curves or kinks always mean that part of the leading edge is swept. On a swept wing the sweep angle may differ from that of the wing, as wing sweep is conventionally measured at the airfoil 25% chord line. However on a delta wing the leading edge sweep defines the wing sweep. Radius and stagnation point A rounded leading edge helps to maintain a smooth airflow at varying angles of incidence to the airflow. Most subsonic airfoils therefore have a rounded leading edge. The degree of rounding is characterised by the profile radius at that point. The airflow divides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truss
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as '' nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments ( torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary ...
