Title (EN) METHOD AND SYSTEM FOR DETERMINING AN ESTIMATION OF AN ANEMOMETRIC PARAMETER IN AN AIRCRAFT
(FR) PROCÉDÉ ET SYSTÈME DE DÉTERMINATION D'UNE ESTIMATION D'UN PARAMÈTRE ANÉMOMÉTRIQUE DANS UN AÉRONEF
Abstract:
(EN) A method and a system are disclosed for determining an estimation of an anemometric parameter of an aircraft, the anemometric parameter selected from a group comprising at least one of an angle of attack, a sideslip angle and a calibrated airspeed, the method comprising obtaining an indication of a state of at least one secondary surface of the aircraft; obtaining an indication of a position of a horizontal primary surface; obtaining an estimation of the load applied on a corresponding actuator used for actuating the horizontal primary surface of the aircraft using at least the indication of the position of the horizontal primary surface and the position of the corresponding actuator; accessing at least one lookup table with the indication of the state of the at least one secondary surface of the aircraft, the estimation of the load applied on the corresponding actuator used for actuating the horizontal primary surface of the aircraft, and the position of the corresponding actuator; obtaining a corresponding estimation of the anemometric parameter of the aircraft associated with the horizontal primary surface; providing the corresponding estimation of the anemometric parameter of the aircraft associated with the horizontal primary surface and wherein the at least one lookup table is generated during a learning phase.
(FR) L'invention concerne un procédé et un système de détermination d'une estimation d'un paramètre anémométrique d'un aéronef, le paramètre anémométrique étant choisi parmi un angle d'attaque, un angle de dérapage et/ou une vitesse aérodynamique étalonnée, le procédé comprenant l'obtention d'une indication d'un état d'au moins une surface secondaire de l'aéronef; l'obtention d'une indication d'une position d'une surface primaire horizontale; l'obtention d'une estimation de la charge appliquée sur un actionneur correspondant utilisé pour actionner la surface primaire horizontale de l'aéronef au moins à l'aide de l'indication de la position de la surface primaire horizontale et de la position de l'actionneur correspondant; l'accès à au moins une table de consultation comprenant l'indication de l'état de ladite surface secondaire de l'aéronef, l'estimation de la charge appliquée sur l'actionneur correspondant utilisé pour actionner la surface primaire horizontale de l'aéronef et la position de l'actionneur correspondant; l'obtention d'une estimation correspondante du paramètre anémométrique de l'aéronef associé à la surface primaire horizontale; la fourniture de l'estimation correspondante du paramètre anémométrique de l'aéronef associé à la surface primaire horizontale, ladite table de consultation étant générée pendant une phase d'apprentissage.
