ABSTRACT

This project shows the flight simulation of flapping-wing air vehicles (ornithopters) based on a refined flapping-wing aerodynamic model; the modified strip theory (MST). Compared with conventional types of micro air vehicles (MAVs), flapping MAVs show more complicated flight behaviors due to their complex wing motions and aerodynamics. In this project, a flight dynamic model of an ornithopter is presented to analyze its stability and controllability. This project focuses on the stabilization and path-following control of the ornithopter by adjusting the flapping frequency and tail-wing’s elevation angle. In spite of its nonlinear and complex behavior, controlling the tail-wing pitch angle can be effective for the stabilization in longitudinal motion of the ornithopter. Ornithopter is one of UAV which utilizing bird flying concept as flight mechanism. This research begins with ornithopter design mechanism, mechanical, electrical and control design followed by manufacturing process. Kinematic and experimental analysis is used to obtain data from the ornithopter. The main purpose of this project is to design a spy device “Ornithopter”, which resembles a bird and helps in bringing a particular area under surveillance. This device (as it resembles a bird) can be used to survey an area without alerting the environment under survey. This reduces the involvement of human resources in risky fields such as survey of forest areas, national border surveillance etc.
