| Abstract | A conceptual design for a Stirling space engine for future NASA missions uses 40 modular heat exchangers, each with its own integral heat pipe to transport heat to the engine. An existing free-piston Stirling engine was modified to serve as a testbed for evaluating the heat-exchanger modules. The design and fabrication of the modules and the engine used for these tests are discussed. Evaluation of the individual heat pipes before installation in the engine is described. The initial test results with the modules in operation on the engine are presented. The results show that the heat exchangers operate successful on the engine. Measured characteristics of the heat pipes agree well with the analytical models. Temperature drops and the conditions at which the sonic limit is encountered also agree with the models. Future test plans are outlined.< |

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.
