The article reports on the study of the concept of developing planes with flapping wings based on natural flyers like birds, bats and insects, which is conducted by engineers at the University of Michigan. According to Wei Shyy, chair of the Aerospace Engineering Department at University of Michigan, natural flyers have some highly varied mechanical properties that have not yet incorporated in engineering. Shhy said that the flapping wings of birds deform due to pressure generated during flight. He added that the current focus of development if on the aerodynamics of flexible wings related to micro air vehicles with wingspans between 1 and 3 inches.
