Silent ApproachSilent approach is a unique project of Embraer, the Royal Dutch Aerospace Laboratory NLR, and German Dutch Windtunnel DNW, and the EFD group. The partners join knowledge and wind tunnel facilities of vastly different scales to improve predictions of noise by the high lift devices (slats and flaps).Read more
3D printing of Architected polymer foamsIn article number 1904668, Claas Willem Visser, Jennifer A. Lewis, and co‐workers describe the fabrication of architected polymer foams by “direct bubble writing”. In this process, bubbles are ejected into air, deposited onto a substrate, and then photopolymerized with UV light, and open‐ and closed‐cell foams with locally graded densities can be printed into 3D objects such as 3D lattices, shells, and out‐of‐plane pillars.Read more
