Paragliding

Paragliders originated in 1984, is from France who deeply love parachuting, gliding wings of aircrew invented a flying movement, currently in Europe, America and Japan are very popular in Taiwan also launched a shares a whirlwind. Paragliders with traditional parachute is different, it is a kind of aircraft.

The basic information

Long ago, humans for searching for a pair of wings for numerous times thought and exploration. In ancient paragliders

The old Chinese earth, like driving on the left space travel "" chang e" and many other about human try flying beautiful legend. Today, the birth of paragliders for human planted a flying wings. People are free to soar, enjoying "off" gravity tranquility and wonderful.

Paragliders originated in the early 1970s, when, some European climbers from the mountain glide down by parachute, experienced a nice feeling and fun, creating a new aviation sports. Initial paragliders is borrowing from the plane parachuting use airfoils square umbrella, it mainly decline is given priority to, drop speed, safety performance is good. Through more than 20 years of development and evolution. Now paragliders longest flight 14 hours above, a maximum flying range more than 300 kilometers, it embodies a kind of man and nature, and have the natural communication chung the favorite.

In recent years, the development of the western countries the sport soon, like Switzerland, Austria, Germany, Spain and other developed countries have numerous flying ace. People driving paragliders hillside run take-off, navigate; in the air, And the mountains shake hands with white clouds, dialogue, body and mind into nature, brandish asperses humanity's brave and strong.

In Asia, Japan, Korea, China's Taiwan province economic developed countries and regions paragliders motion is very popular, lovers ten million people. In the late 1980s, fly into China and rapid development of sports, current registered aviation club has more than 50, formal members over 1400 people often engaged in paragliders flyers to thousands of people.

Structure characteristics

Paragliders usually consists mainly of airfoil canopy, umbrella rope, braces system and control system composed of four. For convenience of custody, carry paragliders with transportation, each with paragliders are also equipped with a back type bags.

Airfoil canopy airfoil canopy, also called the wing, is to create lift and load bearing paragliders of major components. Wing shape, area and the relative motion and airflow velocity, to lift the produce has very big effect. Airfoil canopy by on the wing, under the wing and direction along the wingspan distribution of dozens of forming ribs constitutes. Up and down the wing with ribs suture, forming specific wing shape. Front wing in accordance with ribs transverse arrangement, constitute a certain size inlet. Due to the risers edge is completely closed up and down the wing, so with all ribs between formed one used for storage of air gas chamber.

When the risers with air do relative motion, air is imported into the gas chamber, because the risers edge sealing and cannot eduction, in air rushed pressure effect, canopy lumen produce certain pressure, make this kind of flexible wing maintain certain rigidity and shape. In order to facilitate the intake air inflows, every piece of ribs of inlet parts seam have a certain degree of hardness, bright and clean tinggua plastic strengthen pieces. In the ribs on different parts of, still have the size and quantity ranging from round hole, the purpose is to make the gas chamber between the air is along the wingspan direction and used to balance the whole wing internal pressure, favors keep the canopy shape, avoid canopy inflatable when part of stress unevenness and collapsed.

Umbrella rope, used for the risers with straps system connection, make paragliders as a whole, and maintain paragliders in flight due wing shape. Meanwhile, umbrella rope is paragliders bearing force transmission parts, flying pilots can also be raised by an umbrella rope to implement the effective paragliders manipulated. Usually, umbrella rope by former backward into three groups or four groups, respectively called A, B and C and group D, and in the canopy central axis symmetry distribution. The umbrella rope is usually "Y" in the form of bifurcate shape, canopy under the wing and ribs stitched position and lower canopy connected, can discharge, through the metal loop and the corresponding manipulate belt connected the wing shape and stress state of certain, its length criterion according to manipulate belt connected the wing shape and stress state of certain, the length of the stability criterion according to manipulate and maintaining the Angle of the best positions requirements and determined.

Braces system straps, say again seat belt or condole belt, it by a variety of different function of components, so called it straps system. Braces system should have good comfort and safety. Braces system is fixed and body will pilot with whole wing system connected force components, but also to the human body protection components. In a fixed, connect function, it consists of the Lord set of belt, aglet, chest belt, belts, hip, parachute cable stayed belt, connecting strap and metal ring clasp and fast discharge lock components, around "L" type bag as a whole. These tape, for high strength materials kam ribbon, wide 44 millimeter, broken listed in 12 kilograms more strength. In the human body protection function, it consists of outer for FRP guard board, lined with thick sponge rubber back cushion and seat cushion composition, the more advanced and inflatable mattress, installed in the straps system "L" type backpack interlining, and effectively strengthened to human spine, back and pelvis protective function, prevent human body in take-off and landing when collision obstacles or be towed injured.

Manoeuvring system paragliders control systems, mainly by manipulating belt, manipulate the rope and manipulate the circle (manipulation of great) composition. High-performance paragliders and a pedal add belt device. When need, part rope can also be used to manipulate umbrella. The whole control system in the canopy centerline two side show symmetrical distribution, left, right, top with a manipulation "Y" shape to count and canopy edge is connected, lower limit of the belt after wearing manipulation pulleys and manipulate rings connected through rings respectively drop-down manipulate rope can realize paragliders right and left turn, meanwhile the drop-down manipulate rope is can realize the speed regulation. Paragliders Manipulate rings when not in use, and is located in the buckle phase after manipulation with fixed. Paragliders with roots and manipulate usually consist of two or three roots before and after root upward bifurcate, further divided into three or four main root before backward (respectively through 72112 soak loop) by A, B, C, D group order and delayed-type umbrella rope connections. High-performance paragliders group A manipulation with front have installed two deputy pulleys and A period of acceleration to pedal rope, accelerated devices connected, manipulate with besides using rope connection with umbrella outside, also can be implemented acceleration, deceleration and elimination of higher aspects of manipulations. The only effect flybar accelerated device is in flight when required for increasing slippery full flight speed umbrella. The lower end of the accelerated device with metal rod flybar (accelerated bar) connected to stem from the two acceleration manipulate rope through the straps system in front of the pulley and manipulate with acceleration rope connections. When two pedals metal rod under, A group and group B manipulation by arrangement with down, while the risers front is pulled, Angle is reduced, horizontal speed immediately increase.

Flight principle

Paragliders itself is no power, it is can fly, besides the risers after full of air show special shape outside (flying wing), whole depend pilot control, combined with the atmosphere various characteristics (aerodynamic) flight. Traditional parachute, i.e. general parachute, in the air only to produce resistance, no drop lift, and fly in the sky fly process produces speed and the lift, and its speed and lift is far greater than its resistance. Because in structure, paragliders with airbag canopy lining structure, without full of air, no material before paragliders edges and corners, once the inner balloon full of air, paragliders will appear in the forefront of the edges and corners. So, when the fly in the sky fly by the relative air wing surface under respectively drive flow, resistance with the other's wind parallel, weight and wings above air combine to make paragliders produce speed.

Paragliders is part of the principle of air mechanics, and achieve gliding and aloft purpose. One of the main theory is aerodynamics (i.e. upper and lower paragliders different lengths, when there are speed, air flows through the upper surface, in different paragliders length of surface can produce different pressure difference and pressure side to side pressure small shoved). Paragliders with design airfoils do explanation: when the air flowing through the upper raised-face, for long distance velocity faster pressure decreases and instead flows through the air, because concave lower short distance from velocity slower pressure greaten toughness.it produce below air will wing is faced lift and lower push on the pressure difference for total lift, this is the most basic flight principle.

Besides paragliders can also launched by other external forces (such as: engine power, updraft etc), here we mainly lecture is power flow and heat flow, of course, cooperate terrain and air temperature, humidity, density difference and produce the different proportion of atmospheric, use these natural conditions also can make fly upwards climb until these natural condition disappear so far. The sport involves air learn with various mechanical field, in the next flight time, everyone will slowly learning experience. Flying is an endless learning (which is why will attract people place). Flying wing in the force of gravity produce advance force (tension); lift and drag.
