Abstract

Abstract: A new method measuring the atmospheric parameters was proposed based on acoustic vector sensors located at the wing leading edge, and the atmospheric parameters model was set up based on the airflow velocity distribution sensed by acoustic vector sensor over wing leading edge. According to the symmetric, swept character of wings, velocity vector was decomposed to solve the non-linear equation of model. The expressions of angle of sideslip, angle of attack and free stream velocity were derived. The feasibility of the expressions was verified by wing simulation data from Fluent.
