This book involves the study of flight parameters, wing beat frequency, moment of inertia, and wing movements for developing various aerodynamic forces which have been calculated. The book is intended for biologists, physicists, nanotechnologists, and aerospace engineers. Resilin, an elastic polymer (4 λ) which is present at the base of insects, plays a major role in neurogenic and myogenic insect flyers and influences the physiology of flight muscles. Leading edge vortex (LEV) is a special feature of insect flight. Insect wings have a stalling angle above 60 degrees as compared to a man-made aeroplane's stalling angle which is 16 degrees. The Reynolds number, the knowledge of LEV, and a detailed study of moment of inertia help in developing flapping flexible wings for micro-aerial vehicles. This book serves as an interface between biologists and engineers interested to develop biomimicking micro-aerial vehicles. The contents of this book are useful to researchers and professionals alike.
