Abstract: Low profile portable panels consisting of fiberglass-reinforced plastic cosite mats which include hollow inorganic silica spheres in the plastic resin to reduce weight have recessed molded lips and bushings along all edges for connecting panels together with bolts to form expedient airfield surfacing and repair having high flexural strength and high structural capacity.

Abstract: A portable airfield runway having an anchoring and tensioning system is crised of a plurality of fiberglass reinforced plastic panels anchored with earth anchors at each end of the runway and uses self-contained hydraulic tensioning and load maintenance units to maintain constant tension on the runway while allowing for both expansion/contraction due to temperature and dynamic aircraft braking loads.

Abstract: A highly maneuverable straddle carrier vehicle structure is provided for dling various sizes of containers and outsized loads over rough, unleveled, weak and unprepared soils to meet austere requirements which are beyond the capability of commercial straddle lifts that normally operate on prepared surfaces within specific boundaries of yards and docks. Features include high flotation tires capable of operation over marginal terrain, fording capability, all wheel 360 degree steering and offset wheel yokes which permits automatic changing of wheelbase dimensions for rugged sloping terrain operations and wheel positioning for optimum mobility including lateral and oblique movement and vehicle rotation within its own length for a variety of close quarters operations. Load stabilization devices permit container securing during transit and hinged transverse members operate to reduce torsion and bending moments on the vehicle structure over severe terrain.

Abstract: A membrane of fiberglass-reinforced polyester resin is used as a traffica cover over a compacted backfilled crater and crushed stone base to impart strength to the repair and prevent foreign object damage to aircraft. The membrane cover is usually prefabricated from several fiberglass matting layers of chopped fiberglass strands chemically bonded to woven fiberglass roving and impregnated with a polyester resin; an anchoring system consisting of holes along the cover perimeter and torque set rock bolts are used in conjunction with special steel bushings to secure the cover to airfield pavement surrounding the crater.
