摘要

微飛行器之可見度低，爲極有價值之偵蒐利器。然而，由於尺度小。速度低，造成其飛行雷諾數低，氣動效率差，使微飛行器對外界之干擾相當敏感而操縱困難，在飛行穩定與控制系統之設計上極具挑戰性。本研究旨在探討全翼微飛行器之縱向飛行穩定、控制面設計於組件配置，首先建立線性與性於非線性運動方程，並以風洞試驗數據與理論公式估算氣動力導數，再模擬微飛行器之動態響應，分析其飛行動態穩定性，其結果對微飛行器之飛行性能力瞭解以及外型設計與酬載配置均極有助益。

Since MAVs are of low observability, it is a postential candidate for performing reconnaissance missions. For its small size and low speed, MAV's low Reynolds number flight leads itself to a situation of low aerodynamic damping and high sensitivity to the turbulence, which also bring the challenges in stability and control. The objective of this study is to explore the longitudinal flight stability and control of a whole-wing MAV, including static and dynamic stability analysis, control surface design and components allocations. Based on some low Reynolds number wind tunnel test data and theoretical/empirical formulas, flight stability and maneuverability of a 15 cm whole-wing MAV were thoroughly investigated using linear and nonlinear dynamical models. It is expected that the present results are useful in MAV design.
