Pneumatically or hydraulically shape changeable textile structure for use as e.g. crash protector arrangement for aircraft, has cathode surfaces provided with expansion section, where structure is surrounded by elastic coating

摘要

The textile structure has a fluid guide section formed as a propellant or as a feed line, and a knitted fabric upper and lower cathode surfaces (1,2) provided with an expansion section (5), where the textile structure is surrounded by fluid-tight, elastic coating (4). A sandwich like cascaded arrangement is provided with a pile yarn (3). An expansion sensor is arranged in the expansion section for detecting an expansion condition in the upper and lower cathode surfaces. A pressure sensor is provided in the structure to detect fluid pressure.
