Wing Structure


© Visual Dictionary Online - 2014

A paraglider is made up of a row of cells that are open inside from the leading edge to the trailing edge. When pressurized and filled with air, they give the canopy its rigidity.
The various lines that attach to the pilot's harness give the canopy its shape.
Two toggles (also "brakes") within reach of the pilot connect to the left and right trailing edges. The brakes are the pilot's main control mechanisms.

The lines that are affixed to the wing come down to the attachment point on the pilot via "risers." The pilot's harness has two hefty carabiners that clip onto each set of risers.
These suspension lines provide the wing its shape in flight. A pilot's weight is distributed evenly across the wing when there is tension in the lines.
These lines enable the pilot to change the angle of attack by weight shift or pulling on brake toggles.
