A proposed system architecture for estimation of angle-of-attack and sideslip angle

摘要

This paper examines a method for air data estimation to derive the angle-of-attack and the sideslip angle of an aircraft. ^Continuing on earlier work, this paper proposes an avionics system architecture that, by sensing both the N(y) and N(z) acceleration components of the aircraft, can analytically derive both the angle-of-attack, alpha, and the sideslip angle, beta, in the presence of turbulence. ^A model of the U-2S aircraft is used, along with the control model by the air data estimation system, to compare simulation results against the actual dynamics of the U-2S aircraft. ^Finally, an avionics system architecture for air data estimation is proposed. ^(Author)
