    摘要: A horizontal beam of inverted generally T-shpaed vertical cross section supports edge portions of generally horizontal roof panels on transversely oppositely depending base flanges of said beam with a beam central web portion projecting upwardly between said panel edge portions, preferably in the form of transversely spaced vertical webs. Water proof upper layers of shape selfsustaining material are portioned over the panel upper surfaces and have edge portions which project upwardly from the panel edge portions and terminate spaced upwardly from said panel edge portions. An inverted U-shaped cap is positioned over the beam webs and has downwardly projecting leg portions transversely outwardly of the edge portions of the panel upper layers, said leg portions terminating downwardly overlying said panel upper layers. Transversely spaced webs project downwardly from the cap internally thereof and hook engage the beam webs retaining the cap and beam in assembly, with angled guides preferably being formed on the cap for guiding the beam webs into such assembly. Thus, the upwardly projecting edge portions of the panel upper layers provide water barriers internally of the cap for preventing water from flowing transversely into the assembly and downwardly along the inner edges of the panels.

    摘要: A method and associated system for multi-disciplinary optimization of various parameters associated with a space vehicle that experiences aerocapture and atmospheric entry in a specified atmosphere. In one embodiment, simultaneous maximization of a ratio of landed payload to vehicle atmospheric entry mass, maximization of fluid flow distance before flow separation from vehicle, and minimization of heat transfer to the vehicle are performed with respect to vehicle surface geometric parameters, and aerostructure and aerothermal vehicle response for the vehicle moving along a specified trajectory. A Pareto Optimal set of superior performance parameters is identified.

    摘要: Upright wall panels have vertical side edges thereof aligned and continuously vertically extending side edge opening recesses, semicircular in horizontal cross section, aligned to form an assembled substantially circular recess between assembled side edges, each recess preferably having continuously vertically extending serrations formed therein and spaced horizontally therearound. The panel side edges horizontally telescope a circular cross section, vertical tie bar received within the assembled recesses, the tie bar having a resilient material sleeve the entire vertical extent of said panel side edges horizontally compressed over and inwardly between the recess serrations. At the same time, opposite face surface flanges at one of the panel side edges telescope and horizontally abut similar face surface flanges of the other panel side edge. Bottom edges of the assembled panels rest downwardly on a baseplate having an upwardly extending, semicircular projection received upwardly into downwardly opening, similar serration formed recesses at the panel bottom edges and a resilient material strip covering the baseplate is compressed over the baseplate projection over and between the serrations of the panel bottom edge recesses. Also, parts of the panel bottom edges at opposite face surfaces thereof downwardly compress the resilient material strip against the baseplate and the resilient material strip extends and is compressed beneath the under surface of the baseplate and a horizontal supporting surface.

    摘要: A convex shell structure for enhanced aerodynamic performance and/or reduced heat transfer requirements for a space vehicle that re-enters an atmosphere. The structure has a fore-body, an aft-body, a longitudinal axis and a transverse cross sectional shape, projected on a plane containing the longitudinal axis, that includes: first and second linear segments, smoothly joined at a first end of each the first and second linear segments to an end of a third linear segment by respective first and second curvilinear segments; and a fourth linear segment, joined to a second end of each of the first and second segments by curvilinear segments, including first and second ellipses having unequal ellipse parameters. The cross sectional shape is non-symmetric about the longitudinal axis. The fourth linear segment can be replaced by a sum of one or more polynomials, trigonometric functions or other functions satisfying certain constraints.
