| Abstract | Electrical power is a major driver for nearly all classes of space missions and, consequently, the maximization of available power is an on-going challenge. Advanced missions within the Air Force are investigating the use of flexible PV array systems. The rapidly-evolving technology of flexible thin film PV cells lends itself particularly well to a flexible array concept. A parallel incentive for development of flexible PV arrays are the possibilities of synergistic advantages for certain types of spacecraft, in particular the solar thermal propulsion (STP) vehicle. The large sun-tracking solar concentrators of an STP vehicle present a highly-efficient support and pointing system for a large flexible PV array mounted on the deployed support torus, or the concentrator. The work performed focused on advancing the technologies that will improve and extend the application of solar arrays in a variety of space and aerospace environments. SRS Technologies performed analyses and demonstrated the feasibility of combining thin film PV array technology with methods to manufacture deployable membrane concentrators for solar thermal propulsion. Significant issues addressed were: the interconnection of the newly developed cells, proper thermal control, and electrostatic charge control of the complete system in the space environment. SRS demonstrated a self-metallizing polyimide concept for electrical interconnection of the backplane, and printing PV array interconnect circuitry directly on the thin film prior to lamination to the array. The actions accomplished indicated the feasibility and desirability of a flexible, high specific power, PV array concept and have established a firm foundation and roadmap for development of an operational concept. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
