Benefits and Costs Analysis of Relaxed Static Stability for MAV

Using control augmentation system to relaxed static stability on MAV can greatly reduce triming drag, but also cause weight increase, which, due to lightweight of MAV, sometime is unacceptable. Whether or not using relaxed static stability in MAV design should be carefully balanced. To support such decision making, an algorithm is developed to calculate the benefits from difference on lift, drag, weight, price between stable and unstable design, along with a method to estimate the lift loss and drag increase from static stability. Also, to minimize the lift loss for stable design, the effects of control surface size on lift force and pitch moment is analyzed. Finally, some general rules are given for the small span flying wing MAV control system design.
