| Abstract | One of challenges in building insect-sized flapping MAVs (micro air vehicles) is to realize complex wing motions under severe design limitations in mass and size. In this paper, two examples of insect-sized flapping mechanism which reduces the mechanical complexity of the wings by utilizing flexible structures: One is a 1-DOF butterfly model and the other is a 2-DOF Diptera model. The butterfly model flew forward stably without any active control device. The flight speed depended on the wing flexibility determined by the wing venation pattern. It was found that the venation mimicking a real butterfly prevents excess feathering deformation of the wing, resulting in slow flight. In the 2-DOF Diptera model, wing pronation and supination were realized passively with a flexure film hinge at the wing root. Tethered flapping experiments showed that lift was maximized by optimizing the hinge stiffness. It was also demonstrated that corrugated cross sections of Dipteran wings are useful to increase spanwise stiffness of flexible artificial wings. |

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.
