| Abstract | One way to make a system more affordable is to reduce the number of redundant components. Reducing components while still maintaining a desired level of reliability requires that the functionality of the eliminated, redundant hardware be replaced with a lower-cost option. In this paper, we present a methodology that offers such an option on an aeropropulsion engine. This option is a low-cost secondary control unit with an intelligent logic that can be implemented as a part of the engine health monitoring unit. The low-cost, secondary control unit acts like a back-up control, when the primary control unit becomes faulty. The back-up unit relies on the models and logic stored in the monitoring unit to provide a reduced-envelope capability for the flight vehicle. The basis for the logic is fuzzy reasoning. The reasoning is initiated by observing the behavior of the engine before a fault is developed. |

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.
