Abstract
A stability augmentation system for a forward swept wing aircraft is disclosed that corrects a dynamic instability phenomenon which occurs when the whole vehicle (rigid body) motion couples with the wing structural motion. The sensors are positioned and their output signals combined such that wing structural motion is isolated. Specifically positioned wing control surfaces are operated to suppress such motion with minimal resulting rigid body pitch motion inducing inputs.
