    摘要: The power to weight ratio obtained with a spacecraft's solar array (3) is enhanced by a factor of at least two to five through use of support structure for individual solar panels or solar arrays (31a-17a) containing a curved outwardly bowed surface as deployed that packs essentially flat for storage. Defining a D-shaped wing (15a) in cross-section as deployed, the support structure (4 & 6) for a string of solar cells (10, Fig. 3) provides greater inertia and thereby greater rigidity than prior designs. One member (4) to the support structure is relatively flexible. One-hundred and eighty degree strain energy hinges (19) carried by the other support member (6) outwardly bows that flexible to define a curved sector when the support structure is released from the stowed condition in which the support structure is held relatively thin and flat.

    摘要: A precision deployable boom assembly 10 for terrestrial and celestial applications comprises an extendable and retractable boom 12 having a fixed end 14 , a movable distal end 20 and three or more cables 30 attached to the distal end to form a tripod configuration of the deployed boom. The boom is spring biased to urge extension of the boom and to produce a tensile pre-load in the cables. The cables are wound and unwound by cable drums 28 selectively driven by precise motors such as stepping motors 33 . The cables are preferably formed of graphite which provides high stiffness, light weight and a very low coefficient of thermal expansion. The position of the distal end is highly stable at all deployed lengths of the boom and is also precisely repeatable.
