Multi-layer duct for air distribution in air conditioning systems for vehicles, in particular aircrafts, and an element for fixing the duct to the structure of an aircraft

摘要

A multi-layer duct for distributing air in air conditioning systems for vehicles, in particular for aircrafts, includes at least one layer of a prepreg of resin reinforced with glass fibre fabric and at least one layer of a prepreg of resin reinforced with a hybrid fabric of glass and carbon fibres. The layers are superimposed coaxially. A fixing element is also provided for securing an air distribution duct to the structure of an aircraft, having a saddle-shaped body comprising a base portion for fixing to the structure of the aircraft. The base portion is connected to a pair of arms having respective curved portions at their free ends for fixing by adhesive to the external surface of the duct. The curved portions are shaped so as to mate with the surface of the duct.
