3. INTRODUCTION An Ornithopter, or ornithopter - like Leonardo da Vinci termed them - is an aircraft heavier than air, that flies like a bird by flapping it's wings. The special feature lies in the wings that do not only generate lift but also thrust. An ornithopter (from Greek ornithos "bird" and pteron "wing") is an aircraft that flies by flapping its wings .

4. BIRD’S WING

5. WING’S FLAPPING MECHANISMS The purpose of the flapping mechanism is to convert the rotary motion into the reciprocating motion of flapping wings. The mechanism will be lightweight and fairly simple, and it will provide a fairly symmetrical wing motion so that the ornithopter flies straight.

6. COMPONENTS OF ORNITHOPTER

7. MECHANISM OF FLAPPING It drives a rotating crank. The crank has a connecting rod attached to it, and the other end of the connecting rod is attached to the wing. As the crank goes around, the connecting rod pushes the wing up and down, to account for symmetry we shall use the dual crank system

8. Control Mechanism For steering, swinging of the tail sideways will produce rolling movement. Similarly, up-down movement will alter the nose direction. The stability of the ornithopter will be achieved with the help of the tail.

10. WORKING It is working by flapping its wings by its own . The propeller is replaced by the motion of wings the upward flap gives the low angle of attack

11. APPLICATIONS IT IS USED FOR SPYING PURPOSES IT IS USED FOR MAKING OF BIRD It is the basic foundation for the aeronautics
