A deployable tent assembly for sheltering occupants of an outdoor event includes a tent formed to define a dome such that the tent has the ornamental appearance of an American football helmet. A plurality of tent poles is each integrated into the tent for biasing the tent to define the dome. A balloon is attachable to the tent which comprises a plurality of intersecting members to have the ornamental appearance of a face mask of an American football helmet. A fill port is fluidly integrated into the balloon and the fill port can be fluidly coupled to a source of compressed air for inflating the balloon.

A tethermast and frag wall includes a fabric device having a fill volume fillable with a fill material on a flexible or compliant mast system. The fill volume may be a chambered curtain. The tethermast and frag wall is self supporting, easily deployed, and may be used in connection with a structure or may be deployed stand-alone. A tether system for an air beam structure utilizing a flexible tethermast, an external frag wall or frag curtain, soft couplings, air beam slings, or combinations thereof to reduce the effects of pressure waves, such as blast waves, onto and into an air beam structure and any inhabitants.

The present invention provides a thermal insulation panel (10) having two outer concaved layers (14, 16) and an inner tension (24) member formed by two substantially parallel panels (26,28). The peripheries of the layers and panels are secured to a thermal barrier (22) extending around the periphery of the panel (10) and a vacuum seal (25) seals the edge. In operation, a partial vacuum is created within the panel which causes concaved layers (14, 16) to flatten and tension panels (26, 28) to be placed under tension. This tensional loading creates a strong and rigid structure without the need for internal supports which can create thermal inefficiency.

A temporary maintenance enclosure for the maintenance of at least part of a turbine blade, said enclosure comprises a number of side walls which substantially surround the circumference of a blade in need of maintenance; and a roof extending from said side walls towards said blade; wherein said roof comprises an aperture through which said blade is received.

A portable structure including a solar shade is disclosed. The portable structure includes a frame comprising at least two beams, a main panel extending between the at least two beams, and a solar shade. The solar shade includes at least one solar shade panel spaced above the main panel by at least one inflatable beam to create a space between the solar shade panel and the main panel. The space creates an insulative layer to help regulate an interior temperature of the portable structure.
