摘要：The paper proposes to insulate an aircraft by an air stream barrier running through an annular channel along the cross section of the fuselage. Hot air is supplied to the channel entry at the lower lobe of the aircraft to heat the aircraft before the air is finally delivered into the passenger cabin. As both channel surfaces are neither in uniform temperature nor uniform heat flux, the existent correlation formulas cannot be applied to fulfill the insulation design. This investigation has applied a computational fluid dynamics (CFD) program to model a two-dimensional aircraft section insulated by such an air channel. A partial aircraft cabin mockup is constructed and put to a psychrometric chamber that is conditioned to -19   C for experimental test. The results reveal the air channel is effective to insulate an airplane. Cold sidewall and draught complaints by passengers seated near windows can be much alleviated.
