| Title | The Design and Production of a Novel Ornithopter with a new Flapping Mechanism | ||
| Keyword | |||
| Abstract | The goal of research this thesis is to use the bionic ornithopter on the market as a initial reference, second, go to the market to purchase electronic equipment that conforms the functions of the ornithopter, third, design the appearance ,the airframe and ornithopterˇ¦s flapping mechanism. After assembling and combining, the goal of making an imitation remote control ornithopter will been create. Then, make the mechamism bigger to create an eagle ornithopter, last, simulate four kinds of flapping mechanism and choose the better one to set it up. This dissertation successfully completed a flightable remote-controlled Eagle ornithopter with a 141cm wing span and a 510g weight. After the test, the number of flight hours can reach 8 to 10 minutes. So, no matter the distance or the height, both are better than commercially available toy ornithopter. This thesis also uses a simple lift experiment to test the body's changes in lift at different wind speeds and angles of attack. With the experimental data, we can more understand the influence. After the actual flight test, we also known that flying ability of the mechanism cannot achieve its maximum output when flying at too large or small of attacking angles and wind speeds. Keywords : ornithopter, bionic bird, tapping machine |
