Science and engineering in Manchester chemist visited Manchester in the 1840s. In his research in Manchester, Smith discovered the existence of acid rain, a by product of the industrial revolution. Smith consequently pushed for greater environmental awareness and helped to found the Noxious Vapours Abatement Society in Manchester, which raised awareness of the consequences of poor air. Joseph Whitworth was an engineer and inventor who hailed from Stockport, Cheshire (now Greater Manchester). A talented mechanic amongst various other engineering roles, for long periods of his life, he worked in factories in Manchester. Whitworth would ultimately devise a standard screw thread system, the first of its
Joint Precision Airdrop System Joint Precision Airdrop System The Joint Precision Airdrop System (JPADS) is an American military airdrop system which uses the Global Positioning System (GPS), steerable parachutes, and an onboard computer to steer loads to a designated point of impact (PI) on a drop zone (DZ). It integrates the U.S. Army's Precision and Extended Glide Airdrop System (PEGASYS) and the U.S. Air Force's Precision Airdrop System (PADS) program. PEGASYS consists of several precision airdrop systems, ranging from extra light to heavy payloads, while PADS resides on a laptop which computes the release points for non-steerable parachute systems by means of software capable
