초록

Strain gages embedded in an upper skin structure portion of the wing, near the centerline axis, measures centerline moment and produces a feedback signal used for adjusting the control surfaces of the wing, to produce stabilizing forces. This enables the wings to be designed primarily for strength, not stiffness.

청구항

In an aircraft having flight sustaining wings, a plurality of movable control surfaces distributed along trailing portions of said wings for maneuvering the aircraft, and a separate actuator means for positioning each control surface, a structural feedback system, comprising: strain measuring means carried by a load carrying portion of a wing, near the aircraft center, for measuring bending moment induced strain; AOT sensor means for measuring angle-of-attack forces acting on the aircraft; accelerometer means for measuring acceleration forces acting on t...
