| Abstract | Mathematical modelling and computer simulation has proven to be the tool of choice for supporting the development and operation of shipboard aircraft securing and handling equipment. While other alternatives have been used for specific phases and aspects of operation, the variety of nonlinear effects present and range of analysis types that are required strongly support transient time-domain simulation as the most versatile option. The DYNAFACE® simulation program has been developed over the past fifteen years and is widely used for this purpose, particularly for the analysis of conventional shipboard aircraft designed with wheeled landing gears. Increasingly, a requirement has emerged for the ability to model shipboard aircraft having skid landing gear -- both due to occasional use of land-based aircraft aboard ships and for supporting the design and operation of ship-based UAVs that are often fitted with skid landing gear. This paper describes in detail for the first time recent mathematical modelling resulting in the extension of DYNAFACE® capabilities to include the modelling of skid-equipped rotorcraft both using a fast linear stiffness modelling approach for the gear and using a more-general nonlinear finite element structural modelling approach. In both cases, an efficient skid/deck interface model is used. The two modelling options provide versatility in the type of analysis that can be performed. Sample results from a typical analysis are also presented and discussed. |

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.
