Abstract 1,120,381. Aircraft structures. HANDLEY PAGE Ltd. 7 July, 1965 [7 July, 1964], No. 27998/64. Heading B7W. [Also in Division F2] An airframe component such as a wing comprises a base structure which is subjected to simulated flight loads and its contour checked and corrected, before an outer skin is bonded to it. The base structure comprises panels of honeycomb sandwich 9, 12, sheet metal (35, Fig. 8, not shown) or metal plate (37) having thickened portions (38, Fig. 9, not shown). The wing described is adapted for boundary layer suction, a corrugated sheet 27 bonded to the panel forming collecting ducts communicating with bores in the panel. The outer skin comprises spanwise strips 10, adjacent strips having matching edges achieved by slitting metal panels, adjacent strips coming from adjacent parts of the panels. The gaps between the strips are of constant width or constant taper, and are bonded to spacer strips 17, the gaps between the strips 10 being aligned with the gaps between the strips 17 and the bores in the panels. In assembly, the strips 17 are screwed to jigs and the base structure is bonded to the strips 17. The jigs are removed, the structure is subjected to simulated flight loads and its profile corrected, and the outer skin strips 10 are then bonded to the spacer strips 17.
