Summary
Due to the advantages of small size, light weight, good camouflage abilities, flexibility, and portability, micro air vehicles (MAVs) have been a popular research topic for over 20 years. Flapping flight is an effective method during the environment of low Reynolds number. However, whether it is used for soldiers fighting or search and rescue, the user must place it carefully during carry due to the membrane structure and non-foldable wings of the current FMAVs.
In addition, in the narrow space areas with remote and dangerous, the current FMAVs can’t pass and collect quickly and transmit information. Therefore, the research of deployable FMAVs is urgent needs. Bionics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. This research is the study on design and manufacture of bionic deployable flapping micro air vehicles (MAVs). Based on the research on the high-lift aerodynamic theory and the mechanism of unfolding and folding of the beetle's hindwings, a bionic deployable FMAV is designed, which can realize maneuvering flight under remote control and unfolding and folding the wings automatically. To optimize the aerodynamic performance of designed FMAV, the computational fluid dynamics (CFD) simulation analysis and wind tunnel tests were completed.
