The name of the invention is a reinforced superplastic forming and diffusion bonded structure. An exterior panel for hypersonic transport vehicles is formed of a superplastic metal alloy such as titanium for accommodating high thermal stresses of hypersonic flight. The exterior panel, designed as re-usable on such transport vehicles, includes an exterior skin configured for atmospheric exposure, and an interior skin configured for attachment to structural frame members of the transport vehicles. An intermediate skin is situated between a pair of multicellular cores; each multicellular core issandwiched between the exterior and interior skins, one core being situated between the exterior and intermediate skins, while the other is situated between the intermediate and interior skins. An airflow channel (AFC) extends through at least one of the multicellular cores for cooling of the exterior panel. Each multicellular core is superplastic formed and diffusion bonded to the other, as wellas to its respective pair of skins to form an exterior panel having a unified structure.
本发明的名称是增强的超塑性成形和扩散结合结构。用于高超音速运输工具的外部面板由例如钛的超塑性金属合金形成,以适应高超音速飞行的高热应力。设计成可在这种运输工具上重复使用的外部面板包括配置为用于大气暴露的外部蒙皮和配置为用于附接到运输工具的结构框架构件的内部蒙皮。中间蒙皮位于一对多孔芯之间。每个多孔芯夹在外部蒙皮和内部蒙皮之间,一个芯位于外部蒙皮和中间蒙皮之间,而另一个则位于中间蒙皮和内部蒙皮之间。气流通道(AFC)延伸穿过多孔芯中至少一个,以冷却外部面板。每个多孔芯是超塑性成形的,并且扩散结合彼此,以及扩散结合至其各自的一对蒙皮,以形成具有统一结构的外部面板。
