ABSTRACT:
An inflatable truss frame member for use in the frame of a large inflatable device such as a ship or satellite decoy. A first embodiment, developed for use in satellite decoys, comprises three main inflatable tubes separated by shear load carrying interlacing inflatable tubes. The first embodiment may be manufactured by laminating two MYLAR sheets together using a triangular pattern of adhesive print to form a series of inflatable tubes. Excess material is removed from between the tubes and the edges of the MYLAR are bonded together forming a cylinder to complete the inflatable truss frame member. A second embodiment, developed for the heavier shear loading of ship decoys, comprises three main inflatable tubes separated by a shear load carrying web. The second embodiment may be manufactured by bonding an inner and outer tube made of MYLAR along arcuately spaced strips. The bonded MYLAR forms the separating web and unbonded MYLAR forms three inflatable tubes. Alternately, the second embodiment may be manufactured by separately forming three inflatable tubes and then bonding the separating web material to the inflatable tubes. Rigid stays or battens may be added between the three inflatable tubes when the separating web will not be strong enough to support the shear loading.
