Aircraft cooling duct

摘要

An aircraft structure, for example a wing, includes a section of skin, for example a lower wing panel, the panel defining an external (lower) surface that in use is on the exterior of the aircraft and an internal (upper) surface opposite the external surface, and a duct comprising a section of duct for transporting cooling fluid, for example air, between the internal and external surfaces of the panel from a first location in the panel to a second location that is spaced apart from the first location in a direction substantially parallel to the external surface of the panel. The cooling air cools an electronic hydrostatic actuator (EHA 4b) in the wing 2.

主权项

1. An aircraft structure including a lower skin and an upper skin, comprising:
a section of lower skin, the lower skin defining an external surface that in use is on the exterior of the aircraft and an internal surface directly opposite the external surface, and wherein the section of lower skin is defined by one or more panels, a duct comprising a section of duct defined by a region between the internal and the external surfaces of the lower skin, said section of duct transporting cooling fluid along said region from a first location in the lower skin to a second location that is spaced apart from the first location in a direction substantially parallel to the external surface of the lower skin, wherein the section of lower skin includes a cooling fluid inlet arranged on the external surface of the lower skin, the cooling fluid inlet being in fluid communication with the duct, wherein said section of lower skin includes a cooling fluid outlet arranged on the internal surface of the lower skin, the cooling fluid outlet being in fluid communication with an inlet of the section of duct, and an item of aircraft equipment that in use requires cooling being positioned and configured in fluid or thermal communication with an outlet of the section of duct.
