Abstract:In order to apply the non-constant aerodynamics of the birds’ flight process to the ocean carrier,combined with the requirements of GAC Research Institute,the comprehensive design of a bionic maritime extreme motion carrier based on the low-frequency flight behavior of birds.Using the angle of attack and variable load generated during the movement of low-frequency flying creatures to obtain higher kinetic efficiency than traditional sea vehicles,overcoming the current shortcomings of low maneuverability of sea vehicles;using the principle of motion imagination to match human motion intention with the behavioral logic of birds,it can eliminate the complex operation process and further optimize the driving experience.Obtain a 3D assembly model.Using the principle of low-frequency flight of birds,we make a 1:6 size model for structural realizability analysis,combine the bird body structure,feather structure,movement mode,energy consumption utilization and other aspects with the hull structure and modeling to propose a bird-like hull movement structure.

當萊特兄弟在1903年發(fā)明了世界上第一架飛機——飛行者一號時,人類終于能夠在天空中自由翱翔,實現(xiàn)了第一次可操縱的、有動力的連續(xù)飛行[1]。然而它們必須依靠螺旋槳或獨立的噴氣發(fā)動機來推動機翼和機身前進,相比于理想狀態(tài)下的機翼撲動飛行仍有很大距離。鳥類能夠在飛行的過程中依靠柔性且能夠彎折的羽翼及調(diào)控羽毛間的間隙。實現(xiàn)瞬間的垂直起降、懸停、側(cè)飛甚至后飛退。運用翅膀的揮動承受自身重力,同時施加向下的變載力,獲得向上且前傾的綜合氣動力,為鳥提供升力和向前推力,其具有比傳統(tǒng)載具的定常氣動力理論更高的動能效率。……
