the printed microplane is flying.
professor Shen Haijun, a professor at the Institute of Aeronautics and mechanics, Tongji University, revealed that several teachers and students of the college's Micro plane laboratory have successfully released a newly developed micro aircraft, which used the latest 3D printing technology.
as a wonderful and interesting new and high technology, 3D printing has gradually entered the field of vision in the past two years. So far, the three-dimensional printing technology is still in its infancy, with limited printing consumables, small print size, and weak print material strength. Only a few airlines or individuals have tried to make parts of aircraft or model parts, or a few small flying small aircraft are printed. The state model is used for setting.
SHEN Navy Professor, the successful test flight of the Tongji University 3D printing micro aircraft is the first example in China. It shows the feasibility of the application of 3D printing technology in the design and manufacturing of small aircraft.
, due to the limitation of the maximum print amplitude of the team's existing 3D printers, 28cm becomes the feature size of the micro plane designed by the microplane lab teachers and students. After a rigorous round of aircraft design, the aircraft is determined to be a single wing, a front pull drive, a rear three point landing gear layout, a tail wing, a rectangle. Wing and flat tail, triangular vertical stabilizer, semicircular rudder, lift surface hollowed and rod type fuselage; wing airfoil adopts a flat wing with a relative thickness of 0.1. Eventually, the CAD electronic drawings of the aircraft were converted to STL format for 3D printer recognition, for 3D printer printing.
