18 Jan Why do paragliders fly?
Why do paragliders fly is a question many people ask before their first flight. The answer lies in the aerodynamics of its design and its interaction with air currents. Here’s a basic explanation of why paragliders can lift off and stay in the air.
- Wing design: The paraglider has a flexible wing that resembles a glider’s wing. This canopy is made of strong, lightweight material, and its shape is designed to capture and channel air efficiently.
- Inflation: As the pilot runs forward during take-off, the wind fills the wing, inflating it completely. This inflation creates an airfoil shape that harnesses air currents to generate lift.
- Rising air currents: Once airborne, paraglider pilots look for rising air currents, such as thermals or dynamic lift created by the terrain. These currents provide extra upward force, allowing the paraglider to gain altitude and stay in flight.
- Pilot control: The pilot controls direction and speed using control lines connected to the wing. By tilting and turning the paraglider, the pilot can maneuver and maintain control throughout the flight.
The physics behind why paragliders fly
The core physical principle is the same one that allows an airplane to fly: the pressure difference between the top and bottom of the wing generates lift. In a paraglider’s case, that “wing” is the flexible canopy, whose curved shape makes air flow faster above than below, creating the upward push needed to stay airborne.
In short, paragliders fly thanks to the combination of an aerodynamic design that generates lift and the pilot’s ability to harness air currents. This combination lets paragliding pilots experience the sensation of free, controlled flight.
If you want to see it for yourself, you can live the experience on a tandem paragliding flight in Tenerife alongside a certified pilot, no previous experience required.
