摘要:	飛機在大氣擾流中飛行,其遭受的隨機外力衝擊造成飛機姿態角(Attitude Angle)及軌跡 (Trajectory)隨時間任意變化,運動參數時間反應的強弱(Intensity)與擾流大小(Scale)有嚴密關係,不僅加重結構和駕駛員的負擔,也令乘客產生不舒適(Uncomfortable),甚至不可接受(Unacceptable)的搭乘感覺。因此我們希望經由飛機在大氣擾流中的飛行反應,了解飛機在這些飛行狀況的特性,藉此改善飛航安全,增加乘客搭載的舒適性。本文分別用不同方向:垂直向上陣風(Vertical Wind Gust)和水平逆向陣風(Horizontal Head Wind),及強弱度的變化,對Boeing-747型飛機在不同飛行狀況下,各飛行參數的時間反應以了解飛機特性,再利用不同動力模擬系統:Laplace轉換法,線性、非線性擾動直接積分法,比較各動力模擬系統的可行性及實用性。 An aircraft is always flying in a turbulent atmosphere, and suffers the impact of atmospheric gust winds. The net effect is that this aircraft will change its attitude angle, altitude, and trajectory in a almost randomly fashion, and represents a severe hazard in aviation safety problem. The purpose of this project is to understand the response behavior of several types of aircraft under different gust wind models, in order to investigate the flight characteristic conditions, and improve their flight safety situations. Through the use of four different methods such as Laplace transfer, linear and nonlinear equations of motion, the Boeing 747 transport aircraft's response behavior were fully investigated and compared under vertical wind gust and horizontal head wind influences. Results show that the two Runge-Kutta methods agree well, and will be the best compromise of accuracy and realistic response.
