中文摘要 | 以非破壞檢驗(NDI)技術來判定民航機結構失效極為費時,本文提出一種方法是以安定性與控制導數受到靜氣彈力效應之概念,來間接預測出結構的健整性。氣動力模型是以快速記錄擷取器(QAR)提取飛航資料,藉由模糊邏輯建模技術所建立。使用此氣動力模型可計算出有氣彈力效應的安定性與控制導數,從而預測出可能的結構及飛安問題。本文以一架雙噴射民航機遭遇大氣亂流在飛行中瞬間起伏運動(Plunging Motion)作為案例研究,並呈現該民航機在遭遇大氣亂流前與後之氣彈力效應比較分析結果。本研究由QAR資料進行分析,無須對飛機進行NDI,因此可以及早發現飛機結構之潛在影響,增進飛航安全。 |
英文摘要 | Since non-destructive inspection (NDI) technology to determine structural faults of transport aircraft is very time consuming, a method based on the concept of static aeroelastic effects on stability and control derivatives to indirectly determine the structural integrity is presented in this paper. Aerodynamic models are established by using fuzzy-logic modeling (FLM) of the flight data extracted from quick access recorder (QAR). The aeroelastic effects in terms of stability and control derivatives are then calculated by using these aerodynamic models to predict the possible problems in structure and flight safety. A twin-jet transport aircraft undertaken plunging motions in atmospheric turbulence is applied the study case, and the results of comparison and analysis of the aeroelastic effects of this transports pre and post encountering atmospheric turbulence are presented. Since the present study employs the flight data stored in QAR, NDI is avoided. It can discover potential problems of structure and improve flight safety. |
