Abstract

The invention relates to a flow regulating device for an aircraft environmental control air inlet (11), comprising: a regulating plate assembly (100) mounted on the peripheral wall of an environmental control air passage (10) containing the air inlet (11), the regulating plate assembly (100) comprising a plurality of regulating plates which are adjacent and overlapped pairwise, and the regulating plates are arranged in the flow direction of environmental control air from front to back; the plurality of adjustment plates include a foremost adjustment plate (110) located at the foremost and a rearmost adjustment plate (120) located at the rearmost, the plurality of adjustment plates being movable relative to each other such that a portion of the plurality of adjustment plates opens or closes the air inlet (11). According to the flow adjusting device, the problems that a flexible adjusting piece is not resistant to low temperature and not enough in strength are solved through the rigid adjusting piece, and meanwhile poor fluid motion characteristics caused by a single rigid piece are avoided through the combined rigid piece.

Description

technical field [0001] The invention relates to the technical field of aircraft environmental control, and belongs to the air conditioning system integration technology. Specifically, the present invention relates to the design of an air intake for environmental control of an aircraft, and more particularly relates to a flow regulating device for an air intake for environmental control of an aircraft. Background technique [0002] The ram air system of civil aircraft provides cooling and fresh air sources for the aircraft, and is an important part of the aircraft air conditioning system / environmental control system. It is mainly used for the cooling of aircraft air conditioning systems, fuel inerting systems, and auxiliary cooling systems , It can also be used for ventilation of each compartment. [0003] Since the air inlet is in direct contact with the ram air, there are problems such as large frontal area and severe pressure. The layout of the flow regulating device sho...
