Abstract

The objective of this paper is to develop helicopter flight control laws that minimize unsteady rotor loads while meeting desired handling qualities. These control laws are meant to act solely through the primary flight controls. First, an overview on how the harmonic decomposition methodology is used towards load alleviation control is presented. Next, explicit model following flight control laws are developed to provide insight on how the feed-forward and feedback paths can be used towards load alleviation. Their impact on the handling qualities is also studied. Finally, the control laws are optimized with CONDUIT®.
