Yes, they flap their wings.
Leonardo da Vinci
Leonardo da Vinci is one of the most widely recognized designers of ornithopters, mechanical flying machines that mimic bird flight by flapping their wings. His sketches and designs from the 15th century laid the foundation for modern ornithopter designs.
An ornithopter is a type of aircraft that flies by flapping its wings, mimicking the flight of birds. An example sentence using the word ornithopter could be: "Leonardo da Vinci's sketches of ornithopters demonstrated his fascination with the mechanics of bird flight."
Leonardo DaVinci (1452-1519) designed flying machines such as gliders, ornithopters, and helical rotorcraft. But these were never built. Modern airplanes (heavier-than-air craft) depend on the motors, notably the internal combustion engine and the jet engine, not developed until the 19th century.
Throughout history, various individuals have believed in the possibility of human flight, but one of the most notable figures is Leonardo da Vinci. He conceptualized flying machines in the late 15th century, sketching designs for ornithopters and other aerial devices based on the study of birds. Additionally, in the realm of mythology, figures like Icarus from Greek mythology represent the notion of human flight and the desire to transcend earthly limitations.
