Abstract:
1. An aircraft fuselage sidewall comprising: an aircraft sidewall volume delineated by an aircraft skin forming an outboard boundary of the aircraft sidewall volume, a passenger cabin sidewall forming an inboard boundary of the aircraft sidewall volume and fuselage frame structures forming axial boundaries of the aircraft sidewall volume; a flow controller positioned at a portion of the aircraft sidewall volume to selectably control air flow through the aircraft sidewall volume, wherein the flow controller is positioned at an intersection between a crown and the passenger cabin so as to permit passenger cabin air to be extracted from the crown; and a dividing member disposed in the aircraft sidewall volume to divide the aircraft sidewall volume into an inboard volume between the dividing member and the passenger cabin sidewall and an outboard volume between the dividing member and the aircraft skin, wherein the flow controller is configured, based on an operating mode of the aircraft being an in-flight operation, to restrict flow through the inboard volume to provide insulating properties and simultaneously enable flow through the outboard volume to enable heat transfer between air in the outboard volume and a surface defining the outboard volume, and wherein the flow controller is configured, based on an operating mode of the aircraft being a ground operation, to restrict flow through the outboard volume to provide insulating properties and simultaneously enable flow through the inboard volume to enable heat transfer between air in the inboard volume and a surface defining the inboard volume.
