Paraglider what elements it consists of.
The main elements of the design of the paraglider are:
- Lines, risers
- Harness system
- Emergency parachute
The paraglider is an inflatable wing. In some ways it looks like a parachute, but its shape is elliptical, strongly elongated and not round. The wings are made of a special material that does not allow air to pass - durable synthetic fabric. Two layers of material are sewn together with a gap between them. Vertical ribs of fabric hold two layers together to form separate sections. An open leading edge allows air to freely enter the sections. Sections work like air traps, filling the entire wing until the formation of the correct aerodynamic shape. Experts agree that most wings have a life of approximately 300 flying hours (about four years) before the materials begin to stretch or weaken.
The line system is attached to various areas of the lower edge of the wing proportionally distributing the load over the entire surface. Modern paragliders are equipped with three rows of load-bearing lines. Another row - a number of control lines are attached along the edge of the trailing edge. Lines in rows cascade down to the bottom, connecting together on both sides of the pilot. The lines end (risers) with power belts of the free ends for which the suspension system is fastened with carbines. The control lines end with brakes - control handles. By controlling the brakes, the pilot changes the direction or speed of the paraglider. The braid of the lines is made of synthetic materials such as polyester or nylon. Core - power threads inside of Kevlar are strong and durable. These types of materials are resistant to stretching and compression, which gives the paraglider stability and balance.
The harness system is designed to provide maximum comfort provided by a comfortable seat with lumbar support and safety through safety belts, as well as the ability to clearly transfer pilot control actions to the wing.
The accelerator is used by the pilot to increase the speed of the paraglider. It is attached to the suspension system and connected to the rows of lines using hooks. When you press the accelerator with your foot, the pilot can increase the speed of the paraglider by changing the angle of the wing.
An emergency parachute is used in unlikely, but possible unforeseen flight circumstances, when the wing gets out of control starting to decline irreversibly or there is a possibility of its destruction. The reserve parachute is installed in a special compartment in the suspension system and is attached to it by a power halyard, is protected from accidental deployment and is checked. The reserve parachute is designed so that it quickly opens when ejected.
And of course, a pilot who never flies without a helmet!
