Ground environment mat.

摘要

A ground environment mat for VSTOL aircraft (1) and the like, comprising a porous core element (9) having an upper surface (7) porous enough to permit jet entry and controlling the effect of laterally transmitted ground jets resulting therefrom 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 porous core element may comprise mesh or strands, or twisted flat strips or metal tubes or perforated elements hingedly attached to a backing layer (8).
