    • The instant invention employs the impressive capabilities of modern materials such as plastics, composites, and metal alloys of carrying large tension forces, enabling them to carry compression loads by converting the compressive force of internally contained pressurized fluids into distributed tension forces. The walls and membranes of the pressurized elements, and of the envelopes are not “inflated” as in structures made of flaccid or stretchable materials, but are made of substantially rigid materials whose rigidity is enhanced by the fluid pressures contained within. An important application of the principals set forth herein will be in the use of very high tensile strength materials such as titanium or aluminum that are not often considered for use in compression. The significant weight-savings so achieved make possible new applications that might include exotic airframes: lighter-than-air craft, or small robotic solar-powered aircraft to be used for survey, surveillance, or communication.
    • 本发明采用现代材料(例如塑料,复合材料和承载大张力的金属合金)的令人印象深刻的能力,使其能够通过将内部加压流体的压缩力转换成分布的张力来承载压缩载荷。 加压元件和信封的壁和膜不像在松弛或可拉伸材料制成的结构中“膨胀”,而是由基本上刚性的材料制成,其刚度通过其中包含的流体压力增强。 本文所阐述的原则的重要应用将在于使用非常高的拉伸强度的材料,例如不经常被认为用于压缩的钛或铝。 如此实现的显着减轻重量可能使新的应用可能包括外来机身:轻型飞行器或小型机器人太阳能飞机用于测量,监视或通信。
