Shock-attenuating seamless surface system for use on vertical takeoff and landing zones

摘要

Shock-attenuating seamless surface systems, for use on vertical takeoff and landing zones, can be installed on a base or installed in a recess in the base such that an integrated installation is obtained. PPAll systems have a surface layer with a bottom and outer edges; ribs extending from the bottom of the surface layer for defining an array of air-filled cells affixed to the bottom of the surface layer; and a first layer of sealer and aggregate spread over the surface layer, the outer edges, and the base immediate to surface system.P PMore complex systems may include one or more of the following: a plurality of median ribs extending a shorter distance from the bottom of the surface layer than the defining ribs in order to give added support against a strong blow striking the surface layer and the array of air- filled cells affixed thereto; a void area left in place of at least one median rib in order to facilitate cutting through the surface layer; a second layer of sealer spread under the array of air- filled cells and above the base in order to prevent the escape of air therefrom upon impact thereto and also for holding the array of air- filled cells in a substantially vertical orientation with respect to the base; a sloping outer edge surrounding all sides to help prevent tripping and facilitate access by handicapped person; and a beveled outer edge surrounding all sides for facilitating attachment to the base.
