Ventilation system suitable for air conditioning assembly cabin of aircraft and aircraft comprising same

Abstract

The invention discloses a ventilation system suitable for an air conditioning assembly cabin of an aircraft and the aircraft comprising the same. The ventilation system comprises an injection sleeve which is located at a position close to an exhaust port of a ram air exhaust pipeline of an air conditioning system of the aircraft, wraps a section of the ram air exhaust pipeline, and extends out ofthe surface of a skin of the aircraft, and an adjustable skin air inlet which leads to the air conditioning assembly cabin and is constructed to enable external air to flow into the air conditioning assembly cabin and at least partially flow to the injection sleeve. According to the ventilation system suitable for the air conditioning assembly cabin of the aircraft and the aircraft comprising thesame, the effective circulation area and the circulation amount of the ventilation system can be flexible, the ventilation function of the air conditioner assembly cabin is achieved, and the ventilation system has the advantages of being adjustable in flow, low in fuel oil compensation loss, light in weight and free of temperature rise on the ground.

Description

technical field [0001] The invention relates to the ventilation of an air-conditioning module compartment of an aircraft and the ram air system of the aircraft, in particular to a ventilation system suitable for an air-conditioning module compartment of an aircraft and an aircraft comprising the same. Background technique [0002] As the economic requirements of civil aircraft become more and more stringent, composite materials with lightweight, high structural efficiency, safety, economy, comfort and environmental protection are widely used in the structure and skin of aircraft. Combining more than two kinds of materials, such as reinforcing fibers (glass fiber, aramid fiber, carbon fiber) and organic polymer matrix, in a certain proportion and composition form, so that the properties of various materials complement each other, thus making a kind of New composite materials. Composite materials have ultra-high specific strength and specific stiffness, greatly reduce weight,...

AI Technical Summary

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to overcome the ventilation system of the air-conditioning module cabin in the prior art, which lacks the ventilation flow adjustment function and cannot adjust the effect of regional ventilation and heat exchange according to the needs, and must use high pressure when there is no active flow of external ambient air. The air source drives the turbofan, which will consume valuable engine bleed air and increase fuel compensation loss, which will affect the economy of the aircraft. A ventilation system suitable for the air conditioning component compartment of the aircraft and the aircraft including it are proposed
