Abstract

The invention discloses an air outlet structure of a passenger cabin of a civil aircraft, belonging to the field of aircraft environmental control design. The structure comprises an air outlet housing(1) and a rectifying grill (2), the air outlet housing (1) comprising a first portion connecting an air supply duct, a second portion extending from the first portion to the passenger compartment ofthe civil aircraft, and a third portion connecting with the passenger compartment of the civil aircraft; the rectifying grille (2) is a plate-like structure having through holes provided in the secondportion of the air outlet housing (1) for separating the first portion from the third portion of the air outlet housing (1). Through the rectifying grille provided with several through holes, the gassent in from the outside is evenly distributed, the flow field distribution of the air outlet of the passenger cabin of the civil aircraft is improved, the circulation flow of the air in the cabin ispromoted, the dead zone of the gas flow is reduced, and the comfortable cabin environment is provided for the occupants.

Description

technical field [0001] The invention belongs to the field of aircraft environmental control design, and in particular relates to an air supply port structure in a passenger cabin of a civil aircraft. Background technique [0002] The cabin of a civil aircraft is usually provided with an air supply port near the trunk, and an air outlet is provided on both sides of the bottom of the cabin. After the fresh air comes out of the air outlet, it directly reaches the face of the person. Therefore, a more uniform and stable air supply is required. [0003] The uniformity of the flow field at the air outlet of the air conditioning system is the key to satisfying the comfort of the occupants. However, due to the requirements of space size and beautiful design in the passenger cabin of civil aircraft, the air outlet of the air conditioning system usually adopts a circular structure converted into a rectangular structure. plate, but this method fails to solve the problem of uniformity...
