Aircraft thermal insulation

摘要

The invention provides an arrangement and methods for thermally insulating aircraft, particularly but not exclusively for when the aircraft is operating in extremely hot or cold conditions, and describes an aircraft skin construction comprising a foam- stiffened CFC sandwich panel forming part of the aircraft outer skin mounted to an underlying load bearing aircraft structure (203), wherein the panel at the mounting to the structure comprises two outer layers (207, 209) of CFC material with an inner layer of foam material (211) sandwiched there between.
