초록

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.

청구항

1. A system for augmenting stability of an aircraft having a fuselage and forward swept wings comprising: a control surface mounted on each wing, said control surfaces positioned such that a plane substantially perpendicular to the fuselage center line and which passes through the nominal aircraft center of gravity also passes through said control surfaces; wing sensors mounted near each of said control surfaces for providing first signals indicative of the motion of each wing; fuselage sensor means mounted on the fuselage for providing second signa...
