1. An aerodynamic surface actuation system, comprising:
a plurality of outer tracks, wherein each outer track of the plurality of outer tracks comprises:
an outer roller channel; and
an inner roller channel positioned above the outer roller channel;
an aerodynamic surface connected to a carrier, wherein the carrier comprises rollers configured to move within inner roller channels of the plurality of outer tracks; and
a plurality of fixed rollers mounted to one or more longitudinal structural elements in an aerodynamic structure, wherein the plurality of fixed rollers are disposed within the outer roller channels of the plurality of outer tracks.
