| Abstract | A hybrid underwater glider Petrel-II is presented in this paper. It combines behaviors of traditional autonomous underwater vehicle and those of autonomous underwater gliders. It can dive along a saw-tooth trajectory in the gliding mode and autonomously cruise in the level-flight mode. It is characterized by long endurance, long fight range, high cost efficiency, and good maneuverability. The hydrodynamic characteristics are crucial aspects of consideration and computation in scheme design phase. In this paper, the impact of wing layout on the movement efficiency and stability of the hybrid underwater glider is investigated by design of experiments and computational fluid dynamics method. The results of orthogonal test show that the chord length has the most significant influence on the movement efficiency while the sweep angle has the most remarkably impact on the stability of the vehicle. In addition, field trials were conducted to validate the basic motion function and measurement capability of Petrel-II. Results of the field trials are also presented in this paper. This work provides theoretical guidance for hybrid underwater glider design. |

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.
