News: Advanced manufacturing put to the test


The Star reports that testing has begun on the landing gear of Boeing's 787 Dreamliner. Specialist researchers at the Advanced Manufacturing Research Centre (AMRC) on the Advanced Manufacturing Park (AMP) in Rotherham worked for over 18 months with engineers at Messier-Dowty to develop the optimum machining processes to be adopted in the manufacture of new generation landing gear. Messier-Dowty, along with Boeing are one of the principal sponsors of the University of Sheffield AMRC. Messier-Dowty, an integral member of the Boeing 787 supply team, carried out extensive titanium machining trials in order to reduce the weight of the landing gear. Messier-Dowty will incorporate an increased use of titanium on the main gear, including a titanium inner cylinder, which is an industry first. Boeing has installed the landing gear in the first Dreamliner and started "swing testing," which simulates how the gear will work when the aeroplane lands and takes off. Jay McArthur, general supervisor for the 787's production test told The Star "The test replicates an actual extension and retraction of the landing gear as it would function on a regular flight. "The testing involves swinging the landing gear into a stowed position and back down into a landing position."
