| Abstract | Launch mechnism of coaxial induction coil launcher (CICL) is investigated based on the theoretical analysis of the armature's emf and its effect. The distributions of J in the armature for the given conditions of the dynamic operation and of eddy field are compared, which verifies the correctness of theoretical analysis. In addition, the influences of the armature's motion effect on the accelerative performance of CICL are researched by means of the method of finite element analysis. Researches show that the directions of Je and Jv are opposite in the early launch process. Je has acceleractive function for the armature in early operation process of CICL, and Jv has deceleraction function for the armature. Only Je>Jv, the armature can be accelerated. When Je<Jv and Je changes its direction, the armature will be decelerated. The armature's motion effect has important influences on the acceleractive performance of CICL. The armature speed's enhancement not only results in the increase of Ev and the driving coil's back emf but aslo results in the decrease of the transient time of the armature in the driving coil. These factors are of no avail to CICL working under the high speed conditon. |

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.
