Flight control system for an aircraft
11745851 · 2023-09-05 · ·

A simple, safe, and inexpensive flight control system in an aircraft. An anti-torque system for a rotary-wing aircraft has an airfoil with a first surface extending from a first trailing edge and a leading edge, and a second surface extending from a second trailing edge to join the first surface at the leading edge. The airfoil has a first moveable deflector panel pivotally coupled to the first trailing edge, and a second moveable deflector panel pivotally coupled to the second trailing edge. Means are provided to pivot the deflector panels in unison about their respective pivot axes to alter the direction of travel of the airflow downstream of the pivot axes over the surfaces of the deflector panels, thereby producing a lift in a direction perpendicular to the airflow to counteract the torque applied on the aircraft. The flight control system may be arranged within a fixed-wing aircraft.

Thermoplastic aerostructure with localized ply isolation and method for forming aerostructure

A composite wingbox structure formed of reinforced thermoplastic. The composite includes carbon fiber reinforcement and a plurality of insulation elements to localize the heat formed during the process of manufacturing the structure. The process of manufacturing the wingbox includes the steps of interleaving a series of insulations elements within a plurality of laminae and consolidating the insulation elements and laminae to form a laminate. The laminate is then aligned with a support structure such that the insulation elements overlie the supports structure. The laminate is then fused to the support structure using a non-contact heating process, such as inductive welding.
