Pressure sensing flow stabilization device

The invention belongs to the field of airplane design technology, and relates to a pressure sensing flow stabilization device of an air supply device of an airplane. The pressure sensing flow stabilization device is an improvement of an air supply device of an existing airplane. The pressure sensing flow stabilization device comprises a pitot tube type air inlet channel, an air application device, mounting linings, static pressure tubes, a flexible cover skin and static pressure through holes which are arranged in an airplane body. The flexible cover skin is arranged on the front portion of the inner wall of the pitot tube type air inlet channel, and the periphery of the flexible cover skin is connected with the inner wall of the pitot tube type air inlet channel through glue or rivets. The flexible cover skin and the inner wall of the pitot tube type air inlet channel form a sealed cavity, and the static pressure through holes are formed in the pitot tube type air inlet channel. The static pressure through holes are connected with the static pressure tubes which are communicated with a seat bin or a passenger bin in the airplane. The air application device is arranged on the rear end of the air inlet channel, and the periphery of the air application device is connected with the flexible mounting linings. The outer sides of the mounting linings are tightly connected with the inner wall of the air inlet channel. The pressure sensing flow stabilization device has the advantages of being simple in structure, light in weight, high in reliability, and simple in maintenance.
