Abstract As an important part of the flush air-data sensing (FADS) system, the pneumatic tube has an important influence on the reliability and measurement accuracy of the system. In this paper, the knowledge of fluid dynamics is used to build the dynamic response model of pneumatic tube in the continue flow and the transfer function is deduced. Through the transfer function, the dynamic characteristic of the pneumatic tube has been analysised, furthermore, the design criteria for the pneumatic tube has been formulated. Finally, the simulation results have been showed to prove the dynamic response model and the design criteria of the pneumatic tube, thus providing reference to the design of the FADS system.
