The Principle of Flight of Ornithopters - Paper Presentation And PPT

An Ornithopter, or ornitotero - like Leonardo da Vinci termed them - is an aircraft heavier than air, that flies like a bird by flapping it's wings. The special feature lies in the wings that do not only generate lift but also thrust.Ornithopters are mostly built the size of birds or flying models and then are also called flapping wing model.The basic operating principle of a flapping wing has already been discovered by Otto Lilienthal (1889). To help understanding an effective way of flying of big ornithopters his functional description is still trend-setting to the present day. But much details are still not understood.Always there have been several different versions of the flapping flight theory. They all exist in parallel and their specifications are widely distributed. Calculating the balance of forces even of a straight and merely slowly flapping wing remained difficult to the present day. In general, it is only possible in a simplified way. Furthermore, the known drives mechanism and especially wing designs leave a lot to be desired.
