Flexible duct with sealed insulation for aircraft applications

摘要

A hose for transport of conditioned air between a ground-based heating-ventilating unit and an internal ventilation system of an aircraft comprises at least one hose segment. The hose segment has an end provided with a fastener interconnectable with a fastener on an end of an adjacent hose segment. The hose segment also has an interior insulation layer sealed to inhibit migration of moisture between the insulation layer and the interior of the hose.
