Parachute
A parachute is a device designed to slow an object's descent through an atmosphere by creating Drag (physics), drag or aerodynamic Lift (force), 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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Broadwick
Charles Broadwick (born John Murray, 1870s–1943) was an American pioneering parachute, parachutist and inventor. An executive director of the U.S. Parachute Association, Ed Scott, said "just about all modern parachute systems" use ideas Broadwick developed: "an integrated, form-fitting harness and container system nestled on the back." Broadwick developed the static line, a line from a parachute to an aircraft that pulls the parachute from its pouch. Static lines are still used by paratroopers and novice skydivers. U.S. Army Warrant Officer Jeremiah Jones commented, "[Broadwick] is like the grandfather of paratroopers." Broadwick demonstrated parachute jumps at fairs and taught and equipped famous female parachutist Tiny Broadwick. Early life Born in the 1870s as John Murray, Charles Broadwick grew up in Grand Rapids, Michigan in a poor family. He developed aeronautical interests early in life. At age 13, he had his first ride in a hot air balloon. When the balloon caught fire, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gleb Kotelnikov
Gleb Yevgenyevich Kotelnikov (), was born on , at the household of a St. Petersburg Institute professor who taught higher mathematics and mechanics. His parents moved to Saint Petersburg from Poltava in 1868. Kotelnikov belonged to a theatre-loving family, which enhanced his desire to perform on stage. He was the Russian-Soviet inventor of the knapsack parachute (first in the hard casing and then in the soft pack), and braking parachute. Early life, family and education Gleb Kotelnikov had exceptional musical ability at a young age, becoming proficient on the violin, balalaika, and mandolin and even writing his own music. In addition to music, he was interested in electronics and fencing, and he had exceptional aptitude in building complex gadgets. Using only a used lens and hand-crafting the remaining components, such as photographic plates, he constructed a working camera at the age of thirteen. His father fostered his many interests and supported his ability. After his f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Louis-Sébastien Lenormand
Louis-Sébastien Lenormand (May 25, 1757 – April 4, 1837) was a French chemist, physicist, inventor, monk, and a pioneer in parachuting. Early life Lenormand was born in Montpellier on May 25, 1757 as the son of a clockmaker. Between 1775 and 1780, he studied physics and chemistry under Lavoisier and Berthollet in Paris, where he also got involved with the administration of saltpeter. In this position he learned of the use of scientific and mathematical knowledge in the production of gunpowder. After returning to his natal town, he worked in his father's clock shop while immersing himself in the intellectual community and starting his experiments with parachuting, inspired by the performance of a Thai equilibrist who used a parasol for balance. Before performing the public jump from the observatory tower, Lenormand tested his parachutes using animals. First parachute Lenormand is considered the first man to make a witnessed descent with a parachute and is also credited wit ...

Nylon
Nylon is a family of synthetic polymers characterised by amide linkages, typically connecting aliphatic or Polyamide#Classification, semi-aromatic groups. Nylons are generally brownish in color and can possess a soft texture, with some varieties exhibiting a silk-like appearance. As Thermoplastic, thermoplastics, nylons can be melt-processed into fibres, Thin film, films, and diverse shapes. The properties of nylons are often modified by blending with a variety of additives. Numerous types of nylon are available. One family, designated nylon-XY, is derived from diamines and dicarboxylic acids of carbon chain lengths X and Y, respectively. An important example is nylon-6,6 (). Another family, designated nylon-Z, is derived from amino acid, aminocarboxylic acids with carbon chain length Z. An example is nylon-[6]. Nylon polymers have extensive commercial applications, including uses in textiles and fibres (such as apparel, flooring and rubber reinforcement), molded components fo ...

Renaissance Technology
Renaissance technology was the set of European artifacts and inventions which spread through the Renaissance period, roughly the 14th century through the 16th century. The era is marked by profound technical advancements such as the printing press, linear perspective in drawing, patent law, double shell domes and bastion fortresses. Sketchbooks from artisans of the period ( Taccola and Leonardo da Vinci, for example) give a deep insight into the mechanical technology then known and applied. Renaissance science spawned the Scientific Revolution; science and technology began a cycle of mutual advancement. Renaissance technology Some important Renaissance technologies, including both innovations and improvements on existing techniques: *mining and metallurgy *blast furnace enabled iron to be produced in significant quantities *finery forge enabled pig iron (from the blast furnace) into bar iron (wrought iron) *slitting mill mechanized the production of iron rods for nailmakin ...

Adrian Nicholas
Adrian Nicholas (4 March 1962 – 17 September 2005) was a British skydiver who completed more than 8,000 jumps in 30 countries. He is best known for his successful test in July 2000 of Leonardo da Vinci's (1452–1519) parachute design, proving it to be in retrospect the world's first working parachute. A modified pyramidal design was later also successfully tested by his Swiss colleague Olivier Vietti-Teppa. World records On 12 March 1999, Nicholas stepped out of an aeroplane at . He flew for 4 minutes, 55 seconds and covered a distance of , establishing new world records for the longest sky dive and the furthest human flight. During the attempt the exhaust valve of his oxygen mask froze preventing him from breathing properly for about four minutes. Death On 17 September 2005 Nicholas was jumping in Texel, the Netherlands. While performing a high speed landing manoeuvre, his automatic activation device In skydiving, an automatic activation device (AAD) is a dead ma ...
