Parachute, device that slows the vertical descent of a body falling through the atmosphere or the velocity of a body moving horizontally. The parachute increases the body’s surface area, and this increased air resistance slows the body in motion. Parachutes have found wide employment in war and
Parachute design has changed considerably over the years, from roughly cut shapes to aerodynamic "ram-air" parafoils. Many modern parachutes are quite maneuverable and can facilitate controlled descent similar to that of a glider. In addition, smaller "drogue parachutes" are sometimes used to aid deceleration of a fast-moving vehicle such as a drag racer, a fixed-wing aircraft, or a spacecraft ...
