An improved ground-run/skid-braking and/or maneuvering control system for an aircraft or ground effect machine having an air cushion type undercarriage of the type comprising an elastically retractable inflatable trunk or other air inflatable air cushion confining device fabricated of elastic sheet material. The braking/control system comprises a mechanically actuated multiple spine system disposed interiorly of the trunk fabric; and is operable under pilot control to cause portions of the trunk to curvilinearly project downwardly below the basic footprint level of the trunk when inflated, to provide the desired ground-friction braking/maneuvering effects. The projected portions of the trunk are externally armored by means of wear/tear resistant friction pads which are relatively pleat-folding automatically incidental to elastic contractions of the trunk sheet material, to minimize craft flight drag effects.
