| Abstract | The shift towards More Electrical Aircraft is bringing with it many new technologies and a redesign of the existing aircraft electrical network, both of which require thorough testing before their implementation. This led to the creation of the Copper Bird® test bench which recreates the aircraft electrical system and is used for equipment evaluation and validation. This paper details the development of an accompanying virtual electrical test bench; modelling and real-time simulation of the operation of an aircraft electrical system for conducting verification activities over different aircraft electrical architectures and developing energy management strategies. In this paper particular attention is given to the PEM fuel cell model which has been characterized and validated using a scaled version of the electrical test bench. The model shows good accuracy, giving an average error of less than ±350mV and a max error of only ±3%. Fuzzy logic-based energy management was then developed for a fuel cell and battery-based auxiliary power unit with the fuel cell supplying average load power (whilst acting as a current source) and the battery handling load transients and overload situations. The energy management attains its goals of operating the fuel cell at its average power, in order to extend its lifetime, whilst maintaining the battery state of charge between 50% and 90%, also in order to extend its lifetime as well as maintaining its ability to absorb excess generated power. |

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.
