A ground environment mat for VSTOL aircraft and the like, comprising drag elements controlling the effect of laterally transmitted ground jets resulting from jet entry to the mat, so as to reduce hot gas and debris ingestion by the aircraft\s air intakes, suck-down on the aircraft\s surfaces and ground or deck erosion or heating. The drag elements may comprise or perforated metal twisted flat strips tubes or perforated elements hingedly attached to a backing layer.

A ground environment mat comprising: a single porous layer means for permitting vertical entry of and controlling ground jet flows in all horizontal radial directions within said single porous layer means, said single porous layer means having a height and comprising: an upper surface, said upper surface being sufficiently porous to permit vertical jet flow entry into said single porous layer means while subsequently preventing substantially a ground jet flow escape therefrom, a lower surface, and a plurality of discrete drag elements, each of said plurality of discrete drag elements spanning said height of said single porous layer means, said plurality of discrete drag elements comprising a plurality of spaced apart, twisted flat strips extending in a generally vertical direction from said upper surface to said lower surface of said single porous layer means.
