求翻译：有关动物扑翼飞行的流体力学（或空气动力学）原理问题，目前学术界已有怎样的答案，是否已经完全了解？请知情者不吝赐教，十分感谢。是什么意思？

Flapping-wing flight of the animal fluid (or aerodynamic) theory, at present the answer to the academic community has been how, ever completely understand? Please insiders wing, very grateful.

The animal head-bashing-wing flying the fluid mechanics (or aero) principles, the current academia has been how to answer these questions, has been fully understand? Those in the know us so generously invited 10, thanks.

The related animal throws oneself the wing flight hydromechanics (or aerodynamics) the principle question, at present how answer did the academic circles have, whether already completely understood? Asks the insider liberal with to grant instruction, thanks extremely.

Animal flapping-fluid mechanics (or aerodynamic) principle issue, at present academics how to answer, is already fully understand? Insider wanna, thank you very much.
