Sound absorbing aircraft transparency and method of making same

摘要: The present invention relates to a vibration dampening/sound absorbing aircraft transparency (20) which includes an outboard pane assembly (26), dampening/sound absorbing pane assembly (28) and spacer frame (30) for retaining the (26) and assembly (28) in spaced-apart generally parallel facing relationship provide a space (32) therebetween. (28) is multilayer laminate substrate (40), an adhesive interlayer (42) provided over surface of substrate (40) sound dampening material layer (44) the adhesive adhered by to the (40). In alternative embodiment, aircraft transparency (60) addition the foregoing, transparent electroconductive coating (64) interposed between (40) and facilities (66,68) contact with to pass current through heat the coating sufficiently remove or prevent accumulation fog, ice, frost like on (60).
