To the question of theories and the creation of a mahalet (ornithopter)

Two-thirds of creatures living on earth use flapping wings. Creating similar wings and aircraft based on them for humans has proven to be a very difficult task. Only small models fly, but rarely anyone managed to fly into the air with manned machalets. Despite he fact that many attempts have been made to this end. In our work, a theoretical analysis of such devices created by man was made and some issues of flapping flight were considered.
