Europe has seen the greatest growth in
paragliding, with France alone registering in 2011 over 25,000 active pilots.
Wing
Cross section of a paraglider
Transverse cross section showing parts of a
paraglider:
1) upper surface
2) lower surface
3) rib
4) diagonal rib
5) upper line cascade
6) middle line cascade
7) lower line cascade
8) risers
The paraglider wing or canopy is usually
what is known in engineering as a "ram-air airfoil". Such wings
comprise two layers of fabric that are connected to internal supporting
material in such a way as to form a row of cells. By leaving most of the cells
open only at the leading edge, incoming air keeps the wing inflated, thus
maintaining its shape. When inflated, the wing's cross-section has the typical
teardrop aerofoil shape. Modern paraglider wings are made of high-performance
non-porous materials such as ripstop polyester[12] or nylon fabric.[note 1]

In 1952 Canadian Domina Jalbert patented a
governable gliding parachute with multi-cells and controls for lateral
glide.[2]
In 1954, Walter Neumark predicted (in an
article in Flight magazine) a time when a glider pilot would be "able to
launch himself by running over the edge of a cliff or down a slope ... whether
on a rock-climbing holiday in Skye or ski-ing in the Alps."[3]
In 1961, the French engineer Pierre
Lemongine produced improved parachute designs that led to the Para-Commander.
The PC had cutouts at the rear and sides that enabled it to be towed into the
air and steered, leading to parasailing/parascending.
Domina Jalbert invented the Parafoil, which
had sectioned cells in an aerofoil shape; an open leading edge and a closed
trailing edge, inflated by passage through the air – the ram-air design. He
filed US Patent 3131894 on January 10, 1963.[4]

Paragliders are unique among human-carrying
aircraft in being easily portable. The complete equipment packs into a rucksack
and can be carried easily on the pilot's back, in a car, or on public
transport.[14] In comparison with other air sports, this substantially
simplifies travel to a suitable takeoff spot, the selection of a landing place
and return travel.
Tandem paragliders, designed to carry the
pilot and one passenger, are larger but otherwise similar. They usually fly
faster with higher trim speeds, are more resistant to collapse, and have a
slightly higher sink rate compared to solo paragliders.

Forward launch
In low winds, the wing is inflated with a
forward launch, where the pilot runs forward with the wing behind so that the
air pressure generated by the forward movement inflates the wing.
It is often easier, because the pilot only
has to run forward, but the pilot cannot see his wing until it is above him,
where he has to check it in a very short time for correct inflation and
untangled lines before the launch.
Reverse launch

Paraglider reverse launch, Mam Tor, England
In higher winds, a reverse launch is used,
with the pilot facing the wing to bring it up into a flying position, then
turning around under the wing and running to complete the launch.
