Ornithopter flapping wing aircraft. French inventor Albert Kempf holding miniature flapping wing aircraft,or ornithopters. The ornithopter flies by flapping its pair of wings under the power of a small electric motor. They are designed to provide silent,low-speed flight and could be controlled remotely to navigate through confined spaces,such as the interior of buildings. Such aircraft could be used for surveillance purposes | |
