At rotation, Concorde would rise to a high angle of attack, about 18 degrees.
It has been shown that the instability tonal noise generated at an angle of attack below approximately one degree could involve several complex mechanisms.
The angle-of-attack sensor contributes to the airspeed readings.
In fact, before the penultimate flight, engineers had replaced one of the angle-of-attack sensors.
The angle-of-attack sensor was replaced October 27.
Methodology for accounting for changes in mean angle-of-attack during LCO is also developed.
Wing mean angle-of-attack is also shown to be very important.
In the normal range of operations, the variation of lift coefficient with angle of attack of the vehicle will be approximately linear, {C}_L={a}_Lcdot alpha +{C}_{Lo}={a}_Lcdot left alpha -{alpha}_oright) (13).
where CL and CD represent coefficients of lift and drag, respectively, SP is the area of the wing projected into a plane perpendicular to the airflow (approximately half the true wing area, at an optimal angle of attack) and v represents airflow velocity.
Angle of attack and pitch angle are two distinct conditions.
By using parametric angle of attack profile, optimization algorithm for angle of attack is designed and the impact of angle of attack to footprint is discussed.
