Purilennukid

Purilennukid, often translated as paragliders, are unpowered aircraft consisting of a fabric wing and a harness for the pilot. They are designed to be launched by foot from a slope or towed into the air. The pilot controls the direction and speed by shifting their weight and manipulating control lines attached to the trailing edge of the wing.

The principle of operation relies on the airfoil shape of the wing, which generates lift as air flows over it. By steering, the pilot can influence the airflow and thus the direction of flight. Altitude is gained by flying in rising air currents, known as thermals, or by being towed aloft. Landing is typically achieved by descending in a controlled manner and flaring the wing just before touchdown to slow the descent rate.

Purilennukid are used for recreational flying, sport, and sometimes for expeditions in mountainous regions. They offer a unique experience of silent, unpowered flight, allowing pilots to soar with birds and enjoy panoramic views. Safety is a primary concern, and pilots undergo rigorous training to master the skills required for safe launch, flight, and landing. Weather conditions play a crucial role, and flights are generally conducted in stable atmospheric conditions. The sport has gained popularity worldwide due to its accessibility and the freedom it offers.
