Country of Pub1ication: United St a tes Document Type: CONFERENCE PAPER Must documents available from AIAA Technical Library Other Availability: NTIS HC A12/MF AOI Journal Announcement: STAR8419 A number of structurally efficient configurations for wing-type solar arrays are developed by a combination of deepening the pl anform of the blanket and structure and by partitioning the blanket with battens and frequent a11 achments to the support st ructure. This techn i que reduces the tension required to avoid a low natural frequency for the blanket, and the load reduction results in a lighter structure. The use of three different structures are investigated: the Astromast., the Extendible Support Structure (ESS), and a new beam called the STACBEAM (Stacking Triangular Articulated Compact Beam) and their relative performances are compared. The investigation of the STACBEAM is emphasized because its sequential
