AERODYNAMIC ANALYSIS OF FLUSH-MOUNTED STATIC PORTS PLACEMENT ON THE COMMERCIAL TRANSPORT AIRCRAFT

摘要

Flush-mounted static pressure ports are widely used to sense ambient static pressure on modern commercial transport aircrafts. The flight altitude and flight speed of the aircraft are obtained through the air data computer by the static pressure measured. The fuselage static field is analyzed by computational fluid dynamics(CFD) in this paper. Combined with the used characteristics and design requirements of the static pressure ports ,we can obtain the layout position where the correction rule of the static pressure ports is simple. Through this ,we can laid a good theoretical basis for the design for pore pressure sensor in flight correction obtained high quality measurement accuracy.
