DESIGN, FABRICATION, AND TEST OF AN AEROSPACE PLANE BERYLLIUM WING-BOX.
Abstract
Two virtually identical wing-box specimens were fabricated, each 48 in. long, 25 in. wide, and 6 in - 8 in deep. The first specimen was tested at room temperature and at -65 F; It was designed to fail at 150% of design limit load at -65 F; the failing loads were 156% of design limit values. The second specimen was tested at elevated temperatures (500 F maximum) first for thermal loading only, then to four different combinations of limit mechanical loads and design temperatures, and finally to destruction under combined thermal and mechanical loads. It failed at 150% of design limit loads, as predicted by analysis. The program demonstrated the fabricability of complex aerospace structural components of commercially available beryllium and the predictability of the strength levels of such components.
