In this paper, the new type of active roll stabilizers are mounted on the front and rear axle of an experimental medium-duty truck, which are connected to the frame through their hydraulic actuators.

That is, the tail section lacked horizontal stabilizers, so researchers could test a theory that those components were a key factor in stability problems at transonic speeds up to about Mach 0.9.

The foot stabilizer includes a longitudinally extending spine portion (20) and a plurality of ribs (30, 37) extending laterally therefrom from opposing lateral and medial sides.
