London, July 29 (ANI): University of Southampton engineers have developed and flown the world's first "printed" aircraft, which could revolutionise the economics of aircraft design.
The SULSA (Southampton University Laser Sintered Aircraft) plane is an unmanned air vehicle (UAV) whose entire structure has been printed, including wings, integral control surfaces and access hatches.
It was printed on an EOS EOSINT P730 nylon laser-sintering machine, which fabricates plastic or metal objects, building up the item layer by layer.
No fasteners were used and all equipment was attached using 'snap fit' techniques so that the entire aircraft can be put together without tools in minutes.
The electric-powered aircraft, with a 2-metres wingspan, has a top speed of nearly 100 miles per hour, but when in cruise mode is almost silent.
The aircraft is also equipped with a miniature autopilot developed by Dr Matt Bennett, one of the members of the team.
"The flexibility of the laser sintering process allows the design team to re-visit historical techniques and ideas that would have been prohibitively expensive using conventional manufacturing," said Professor Jim Scanlan who led the project with Professors Andy Keane. (ANI)
