The invention discloses a main landing gear cabin ventilation device and an aircraft, relates to the technical field related to aircraft environment control oxygen, and aims to solve the problems that an existing ventilation device cannot adjust the ram air flow in a main air supply pipeline according to the temperature of an aircraft wheel assembly, and the economical efficiency is low. The main landing gear cabin ventilation device comprises a main air supply pipeline, a ventilation disc and a flow adjusting structure, the ventilation disc is provided with an air inlet end face, and air inlet holes are formed in the air inlet end face; the flow adjusting structure comprises a baffle, the baffle is arranged on the leeward side of the air inlet end face of the ventilation disc and connected with the transmission part, the heat transfer part is connected with an air collecting cover of the airplane wheel assembly and the air bag so as to heat or cool air in the air bag to enable the air bag to expand or contract, one end of the transmission part is connected with the air bag, and the other end of the transmission part is connected with the baffle. The transmission part is driven to move through expansion or contraction of the air bag, so that the baffle rotates relative to the air inlet end face, the circulation area of the air inlet hole is adjusted, and flow adjustment of the main air supply pipeline is achieved.

    本申请公开了一种主起落架舱通风装置及飞行器,涉及飞机环控氧气相关技术领域,用于解决现有的通风装置无法根据机轮组件的温度调整主送风管路内的冲压空气流量,其经济性低的问题。本申请提供的主起落架舱通风装置包括主送风管路、通风盘和流量调节结构,通风盘具有进风端面,进风端面设有进风孔;流量调节结构包括挡板,挡板设于通风盘的进风端面的背风侧,并与传动部件连接,传热件连接机轮组件的集风罩和气囊,以加热或冷却气囊中的空气使气囊膨胀或收缩,传动部件的一端与气囊连接、另一端与挡板连接,并通过气囊的膨胀或收缩带动传动部件运动,进而实现挡板相对进风端面转动,以调节进风孔的流通面积,实现主送风管路的流量调节。
