Document Type: REPORT Most documents available from AI A A Technical Library Other Availability: NTIS HC A06/MF AOI Journal Announcement: STAR8507 Although a specific configuration has not been selected for the Space Station, a gravity gradient stabilized station as a basis upon which to compare various structural and construction concepts is considered. The Space Station primary truss support structure is described in detail. Three approaches (see sketch A) which are believed to be representative of the major techniques for constructing large structures in space are also described in detail so that salient differences can be highlighted.

Country of Publication: United States Document Type: PREPRINT Most documents available from AIAA Technical Library Journal Announcement: IAA8507 This paper discusses momentum management for the CDG Planar Space Platform. The external torques on the Space Station are assumed to be gravity gradient and aerodynamic with both having bias and cyclic terms. The integrals of the cyclic torques are the cyclic momenti which will be stored in the momentum storage actuator. Various techniques to counteract the bias torques and center the cyclic momentum were investigated including gravity gradient desaturation by adjusting vehicle attitude, aerodynamic desaturation using solar panels and radiators and the deployment of flat plates at the end of long booms generating aerodynamic torques.
