Problems solved by technology

However, during aircraft configuration changes (e.g., relocation of wing control surfaces, wing lift or drag devices, landing gear, thrust level changes, etc.), these elevators are typically used to counteract the resulting change in the aircraft's pitching moment rather than to steer aircraft, thereby reducing the overall maneuverability of the aircraft

Embodiment Construction

[0017] Methods and apparatus for controlling an aircraft horizontal stabilizer are disclosed herein. Changes in aircraft configuration (eg, relocation of wing control surfaces, wing lift or drag devices, landing gear, and / or changes in thrust levels, etc.) may result in changes in the aircraft's pitching moment. This change in pitch moment can be counteracted by a similarly sized reverse pitch moment, for example, to maintain relatively stable flight. This counteracting pitching moment is typically produced by a combination of fast-moving elevators that may sit on a relatively slow-moving horizontal stabilizer. In these instances, the pitching moment imbalance is mainly counteracted by the rapidly moving elevator. The relatively slow horizontal stabilizers are then placed to return the elevators to their original position. This positioning of the elevators to counteract changes in pitching moments caused by changes in aircraft configuration may reduce the maneuverability of ...

Abstract

The present invention relates to a method and an apparatus to control an aircraft horizontal stabilizer. One described method includes calculating, using a processor, a desired movement of a horizontal stabilizer of an aircraft to counteract a pitching moment of the aircraft, and controlling the horizontal stabilizer based on the desired movement.

Description

technical field [0001] This patent relates generally to aircraft, and more particularly to methods and apparatus for controlling an aircraft's horizontal stabilizer. Background technique [0002] Some aircraft utilize control surfaces (eg, dynamic surfaces, etc.) to control and / or steer the aircraft. Specifically, elevators located on the horizontal stabilizer(s) are used to steer the aircraft longitudinally. However, during aircraft configuration changes (e.g., relocation of wing control surfaces, wing lift or drag devices, landing gear, thrust level changes, etc.), these elevators are typically used to counteract the resulting change in the aircraft's pitching moment rather than to steer aircraft, thereby reducing the overall maneuverability of the aircraft. Contents of the invention [0003] An example method includes calculating, using a processor, a desired movement of a horizontal stabilizer of the aircraft to counteract a pitching moment of the aircraft, and contr...
