In addition, laying radar-absorbing materials on the inner wall of the pipe can effectively reduce RCS, and aerodynamic and stealth multi-objective optimization design for 3D surface bulging in the supersonic inlet can further improve structural-stealth integrated efficiency [108]. However, the ...
(those aren’t smudges on the wall. They’re on your monitor. You should really clean that. Gross). And then I let the kids do whatever they wanted with them, which mostly meant a lot of Lego minifigures: Milo’s shelves: And Gus’s: We’ve got one more project to finish up fo...

[57] designed a honeycomb with adjustable mechanical properties, but there is a lack of research on the mechanical enhancement of the designed honeycomb. Drawing inspiration from the biomimetic idea of variable density, this study designs honeycomb blocks with local various wall thicknesses. It is ...
