Parachute

A parachute is a device designed to slow an object's descent through an atmosphere by creating drag or aerodynamic lift. It is primarily used to safely support people exiting aircraft at height, but also serves various purposes like slowing cargo, aiding in space capsule recovery, and stabilizing vehicles or objects. Modern parachutes are typically made from durable fabrics like nylon and come in various shapes, such as dome-shaped, rectangular, and inverted domes, depending on their specific function.

The concept of the parachute dates back to ancient attempts at flight. In 852 AD, Armen Firman, in Córdoba, Spain, made the first recorded jump with a large cloak to slow his fall. Renaissance figures like Francesco di Giorgio Martini and Leonardo da Vinci later sketched designs resembling modern parachutes, but it wasn’t until the 18th century that the first successful jumps occurred. French Louis-Sébastien Lenormand made the first public jump in 1783, and he coined the term "parachute" in 1785. In the following years, key advancements were made by figures like André Garnerin, with parachutes becoming lighter, more reliable, and easier to deploy.

By the time of World War I, parachutes had become essential for aviators, and significant improvements were made to their designs, including the introduction of the backpack-style parachute by Charles Broadwick and Gleb Kotelnikov's knapsack parachute. After World War II, parachuting became a popular sport, and new materials like nylon replaced silk. Today, parachutes are used in military, recreational, and emergency situations, continuing to evolve with advances in technology and design.
