Correction of sonic anemometer angle of attack errors [PDF]

Agricultural and Forest Meteorology, 2006
An improved method of correcting for the angle of attack error resulting from the imperfect (co)sine response of ultrasonic anemometers is proposed. The angle of attack, which was calculated as the arctangent of observed wind vectors, contains the angle of attack errors in the vectors themselves, and hence this angle was 'false'.

High Angle of Attack Velocity Vector Rolls

IFAC Proceedings Volumes, 1994
Abstract This paper presents the design of a flight control system for performing the velocity vector roll maneuver at high angles of attack. A six degree of freedom model is developed, and the multiple-input multiple-output Quantitative Feedback Theory (QFT) robust control design method is used to treat both the inherent system nonlinearities and ...

The angle of attack

IEEE Instrumentation & Measurement Magazine, 2001
The author considers the angle-of-attack compensator and the static pressure sensor. A true angle of attack is required to correct static and dynamic pressures. Static pressure is necessary to calculate altitude. Dynamic pressure is necessary to calculate speed. Sensing the angle of attack is crucial to correcting all sensed parameters.
