Avian Java
The Avian Java is a British high-wing, single-place, advanced sports hang glider, designed by Steve Elkins and Neil Hammerton and produced by Avian Limited of Hope Valley, Derbyshire.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 42. Pagefast Ltd, Lancaster OK, 2003. ISSN 1368-485X Design and development The Java was designed as an advanced recreational hang glider. It was later developed into the "topless" Java Comp 150 which dispensed with the kingpost and top wire rigging, although it retained the lower flying wires. The Java Comp 150 later evolved into the Avian Cheetah competition glider. All Java models are British Hang Gliding and Paragliding Association certified. The Java 155 model is typical of the line and is made from aluminum tubing, with the wing covered in Dacron sailcloth. Its span wing has a nose angle of 125° and an aspect ratio of 7.0:1. The acceptable pilot hook-in weight is . The Java 155 can be folded up to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hang Glider
Hang gliding is an air sports, air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or Composite material, composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame. Early hang gliders had a low lift-to-drag ratio, so pilots were restricted to gliding down small hills. By the 1980s this ratio significantly improved, and since then pilots have been able to Lift (soaring), soar for hours, gain thousands of feet of altitude in thermal updrafts, perform aerobatics, and glide cross-country for hundreds of kilometers. The Federation Aeronautique Internationale and national airspace governing organisations control some regulatory aspects of hang gliding. Obtaining the safety benefits of bein ...

High-wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

Hope Valley, Derbyshire
The Hope Valley is a rural area centred on the village of Hope, Derbyshire, in the Peak District in the northern Midlands of England. The name also applies to the post town that includes the surrounding villages. Valley Although the Hope Valley appears to be a single valley, the name of the river changes several times. The head of the valley lies below Mam Tor at Castleton, widely regarded as the capital of the valley. From here, the Peakshole Water flows to Hope, where it enters the lower reaches of the River Noe, which has flowed from Edale. The Noe then flows to Shatton near Bamford, before entering the River Derwent, which has travelled about ten miles from Bleaklow. The valley is now technically the Derwent Valley, but the term "Hope Valley" is still used as the Derwent flows through Hathersage and Grindleford. Other streams in the area include the Burbage Brook, which runs down from Burbage Valley through Padley Gorge and into the River Derwent near Grind ...

Kingpost
A king post (or king-post or kingpost) is a central vertical post used in architectural or bridge designs, working in tension to support a beam below from a truss apex above (whereas a crown post, though visually similar, supports items above from the beam below). In aircraft design a strut called a king post acts in compression, similarly to an architectural crown post. Usage in mechanical plant and marine engineering differs again, as noted below. Architecture A king post extends vertically from a crossbeam (the tie beam) to the apex of a triangular truss. The king post, itself in tension, connects the apex of the truss with its base, holding up the tie beam (also in tension) at the base of the truss. The post can be replaced with an iron rod called a king rod (or king bolt) and thus a king rod truss. The king post truss is also called a "Latin truss". In traditional timber framing, a crown post looks similar to a king post, but it is very different structurally: wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Wires
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more i ...
