Abstract:
1. An aircraft system comprising: an air circuit extending from an air intake to an air discharge; and a plate closing said air discharge, said plate comprising a peripheral frame adapted to be connected to an aerodynamic surface of an aircraft, said plate having plural openings delimited by intermediate zones and at least one longitudinal reinforcement that separates said plural openings into at least two stages, said intermediate zones being a flat surface and said at least one longitudinal reinforcement being a flat surface coplanar with the flat surface of said intermediate zones and arranged to be an extension of the aerodynamic surface of the aircraft, wherein a largest dimension of said intermediate zones is oriented perpendicular to said at least one longitudinal reinforcement, wherein a pair of said plural openings, one from each of said two stages, perpendicular to and separated by said at least one longitudinal reinforcement have a same length in a direction perpendicular to said at least one longitudinal reinforcement, and wherein a width of said at least one longitudinal reinforcement between said pair of plural openings is more than the length of one of said plural openings in said pair and less than twice this length.
