An ornithopter is an aircraft that flies by flapping its wings. It is designed by imitating the flapping wing flight of birds. An effective ornithopter will have wings capable of generating both thrust (forward propeling force) and lift (force that keeps the craft airbone). These forces must be strong enough to counter the effects of drag and weight of the craft. Practical applications capitalize on the resemblance to birds or insects. They can be used for military applications such as aerial reconnaissance without alerting the enemies that they are under surveillance .
