The invention discloses an airflow system with a telescopic baffle structure and a control method thereof.The airflow system comprises an air inlet channel and an air outlet channel which are arranged on the two sides of an environment control system, the air inlet channel and the air outlet channel communicate with the environment control system, and a notch is formed in the bottom of an air outlet of the air outlet channel; a containing groove corresponding to the notch is formed in a skin conformal with the exhaust channel, a baffle penetrating through the skin is installed in the containing groove, the baffle is matched with the notch in size, the baffle is connected with a driving device, the driving device is connected with the pod wall, and the driving device can drive the baffle to move in the containing groove so that when the baffle protrudes out of the skin, the baffle can move in the containing groove. The wake flow negative pressure effect is improved, and the pressure difference between the air inlet of the air inlet channel and the exhaust port of the exhaust channel is enhanced. The wake flow negative pressure effect can be effectively improved, the pressure difference between the air inlet and the air outlet is enhanced, and therefore the air entraining amount and the refrigerating capacity of an environment control system are improved.

    本发明公开了一种具有可伸缩挡板结构的气流系统及其控制方法,包括设置在环控系统两侧的进气道以及排气道,进气道以及排气道分别与环控系统连通,排气道的排气口底部开设有缺口,与排气道共形的蒙皮上开设有与缺口对应的容纳槽,容纳槽内安装有贯穿蒙皮的挡板,挡板与缺口的尺寸匹配,挡板连接有驱动装置,驱动装置与吊舱舱壁连接,驱动装置能够带动挡板在容纳槽内移动,以在挡板突出蒙皮时,增大尾流负压效应,增强进气道的进气口与排气道的排气口之间的压差。本发明能够有效增大尾流负压效应,实现进排气口压差的增强,从而提升引气量与环控系统的制冷量。
