THE HISTORY OF WINGSUITS
Wings first became present in freefall skydiving in the 1930s as an attempt to stabilize the skydiver, because no one yet knew how to control themselves in freefall. These early wingsuits were made of materials such as canvas, wood, silk, steel, and even whale bone. These wings often sealed the fate of those who donned them. Between 1930 and 1961, 72 of the 75 original birdmen died trying their wingsuits. Some of these birdmen, like Harry Ward and Leo Valentin, learned to master their wings and this led to the first real understanding of freefall aerodynamics.
In the mid 1990s, French skydiver Patric de Gayardon developed a wingsuit that had unparalleled safety and performance. Unfortunately, Patric died on April 13, 1998 while flying his wingsuit, due to a rigging error. However, Patric planted the seed that grew a new generation of birdmen.
In 1998, Jari Kuosma and Robert Pecnik fulfilled their dream of creating a wingsuit that was safe and accessible for all skydivers when they established BirdMan, Inc. BirdMan's Classic was the first wingsuit offered to the general public. Loïc Jean-Albert developed a one-wing design which was manufactured and marketed by Parasport Italia as the Crossbow in 2000. With a new level of safety and performance, the birdmen are back and rapidly growing.
The wings on a wingsuit are fairly similar to a parachute. They are equipped with crossported cells that inflate with air through inlets in the front of the wings, allowing them to become rigid and aerodynamic. Some wingsuits use airlocks or deflectors to help maintain pressurization and airflow while minimizing turbulence. The surface area of the wing causes dragFor a solid object moving through a fluid, drag is the sum of all the aerodynamic or hydrodynamic forces in the direction of the external fluid flow. It therefore acts to oppose the motion of the object, and in a powered vehicle it is overcome by thrust. vertically, while the shape of the wings and the pilot's body position causes the skyflyer to move across the sky at very high speeds. The resulting forward speed translates into lift (force)Fluid dynamics Lift consists of the sum of all the aerodynamic forces normal to the direction of the external airflow. Lift is created as an airstream passes by an airfoil which deflects the air flow downward. The force created by this deflection (acceler potential and creates a slow fall rate which gives the pilot a relatively high glide ratio.
Wingsuits attach to a skydiving rig using openings on the sides of the suit to insert the leg straps, which stay inside the suit at all times. The arm wings go through the main lift webbing and are then secured with cutaway cables. The cable is routed in a manner that leaves the emergency handles exposed. All suits have booties, swoop handles, and zippers to keep the skyflyer sealed in. It usually takes five to ten minutes to hook up a wingsuit.
Currently, there are three basic wingsuit types. BirdMan's wingsuits have three individual ram-air wings attached to a body. The one-wing design has wings that are essentially "shaped" out of a single piece of material. There is also an experimental design which has wings that run from the wrist to the ankle, and a leg wing.
