METHOD AND APPARATUS FOR MINIMIZING DYNAMIC STRUCTURAL LOADS OF AN AIRCRAFT

摘要

A method of dynamically alleviating loads generated on an aircraft by a disturbance of gust and/or turbulence. The method comprises monitoring, during flight of the aircraft, to automatically detect a disturbance due to gust and/or turbulence and determining an incidence angle or angle of attack of the disturbance. When a disturbance due to gust and/or turbulence is detected, automatically generating control commands for deflecting control surfaces dependent on the incidence angle or angle of attack, and applying the control commands to deflect the control surfaces.

1. A method of dynamically alleviating loads generated on an aircraft by a disturbance, the method comprising:
monitoring, during flight of the aircraft, to automatically detect a disturbance due to at least one of gust and turbulence and determine an angle of attack of the disturbance; when the disturbance is detected, automatically generating control commands to deflect control surfaces dependent on the angle of attack in order to dynamically alleviate loads generated on the aircraft by the disturbance; applying the control commands to deflect the control surfaces accordingly; and adapting the control commands based on an amount of the angle of attack and a gust length representing a duration of the gust over time to adapt the deflection of the control surfaces both to the angle of attack and the gust length.
