Abstract
An aerodynamic drag reducing device reduces drag on a vehicle when in an extended configuration. The aerodynamic drag reducing device includes a moveable frame, a set of linkages, and a linkage coordinator. The set of linkages supports the moveable frame in an extended configuration and a retracted configuration. A first linkage of the set of linkages defines a first axis, and a second linkage of the set of linkages defines a second axis. The linkage coordinator coordinates movement between the first linkage about the first axis and the second linkage about the second axis. The first and second axes may be non-parallel.
