Date: 12-13-82 Classification: u Keywords: solar cells, space energy conversion, fabrication technology Abstract: One of the characteristics of bus platform is the availability of a large amount of power. So, it requires large deployable solar arrays generating several tens of KW of electric power. To develop these arrays, it is essential to identify the critical technologies and problem areas. Therefore, we ATTACHMENT : investigated the storage method, blanket/mast configuration, drive mechanism, power transfer assembly and wiring. As a result, we have a prospect of developing solar array generating more than 25 KW by adopting flexible type arrays and extension mast.

Date: 12-13-82 Classification: u Keywords: laser, space energy conversion, alternative systems, transportation, materi als Abstract: A solar pumped 1aser system has potential advantages over other energy conversion and transmission systems in that the energy generated can be transmitted without further conversion (Ref.l). This makes the system simple, reliable and dependable yielding a low maintainance cost. Laser beam is ATTACHMENT : suitable, or optimal in some cases, for energy transmission from a power generator satellite to a non-powered satellite, or from space to ground. This system has potential application area including laser power propulsion, materials processing and others (Ref.2). For assessment and feasibility of solar pumped 1aser system, a brief survey is given on the status of the developments, and some aspects of space systems are described.
