The invention relates to reinforced super-plastic formed and diffusion bonded structures. An exterior panel is formed of super-plastic materials, including an exterior skin of titanium to accommodatehigh thermal stresses imposed on hyper-sonic transport vehicles during hyper-sonic flight. The exterior skin is fixed to an underlying reinforcing skeletal structure consisting of a super-plastic formable reinforcement (SFR) layer, for example a titanium, zirconium, and molybdenum (TZM) alloy, which supports the exterior skin whenever the latter may be heated to temperatures exceeding 1200 degreesFahrenheit. The exterior panel includes a separate interior skin configured for attachment to a frame member such as a rib, stringer, or spar of the hyper-sonic transport vehicle. A multicellular core is sandwiched between the exterior and interior skins to impart tensile and compressive strength to the exterior panel. In one disclosed method, the core is super-plastic formed and diffusion bondedto the exterior and interior skins.
本发明的名称是增强的超塑成形和扩散结合的结构。由超塑性材料形成外面板,其包括钛的外蒙皮以适应特超音速飞行期间施加在特超音速运输载具上的高热应力。该外蒙皮被固定到下面的增强骨架结构上,所述增强骨架结构由可超塑成形的增强(SFR)层组成,例如钛、锆和钼(TZM)合金,当该外蒙皮被加热至超过1200华氏度的温度时该增强层支撑该外蒙皮。外面板包括单独的内蒙皮,该内蒙皮被配置用于附接到框架构件,诸如特超音速运输载具的肋、纵梁或翼梁。多单元芯被夹在外蒙皮和内蒙皮之间,以赋予外面板拉伸和压缩强度。在一种公开的方法中,该芯是超塑成形的并且扩散结合到外蒙皮和内蒙皮。
