A kind of ventilation system for projecting wind along the aisle of aircraft cockpit

Abstract

The invention discloses a ventilation system for projecting and supplying air along an aircraft cabin aisle, comprising an air supply port and an air exhaust port. The air outlet is arranged on the roof of the cockpit aisle and the lower part of the seat on both sides of the aisle, and the top air outlet is an orifice or louver tuyere connected at the end of the top air duct arranged longitudinally along the fuselage; the air outlet at the lower part of the seat is in the shape of a long strip It is connected with the air supply branch pipe under the seat, and is arranged on the seat structure next to the aisle along the direction of the fuselage, and the air supply opening is embedded with louvers; the air exhaust opening is arranged on the ceiling near the bulkheads on both sides and the cabin symmetry axis on the top panel (applicable to dual-aisle cockpit); the ventilation system includes three independent air supply modes that can be used in combination, including high-speed downward air supply from the top panel, low-speed ceiling air supply, and air supply under the seat, which can be used in combination with the aircraft. In different stages of disembarkation and flight, it provides a comfortable thermal environment for passengers and flight attendants, reduces the discomfort caused by the blowing of the feet caused by the existing replacement ventilation design, and improves the air quality of the cabin.

Description

technical field [0001] The invention belongs to the technical field of ventilation of passenger aircraft, and relates to a ventilation system for projecting air along a cockpit aisle of an aircraft. Background technique [0002] With the process of globalization, airplanes are gradually becoming the mainstream means of transportation. Aircraft rely on airflow patterns created by the Cabin Environmental Control System (ECS) to provide a comfortable and healthy cabin environment. Reasonable airflow organization can enable the pollutants in the cabin to be discharged out of the cabin in the shortest path and the fastest time, reduce the cross-mixing of the air in the cabin, and ensure that the passengers inhale relatively clean air. [0003] According to the mixing of supply air and cabin air, the current air flow organization modes designed for the cabin can be divided into two categories: one is the mixed ventilation based on the dilution principle, which mixes the supply ai...

AI Technical Summary

Problems solved by technology

The air supply outlets of the cabin replacement ventilation currently designed are located at the bottom of the cabin’s two side walls. When cooling the cabin, the cold air sent from the bulkhead directly blows at the ankles of the passengers, causing strong discomfort to the passengers.

In addition, the passengers next to the bulkhead are also affected by the cold radiation from the bulkhead, together with the cold wind blowing from the ankles, the discomfort is further aggravated
