Title (EN) A VEHICLE GUIDANCE SYSTEM AND METHOD THAT USES AIR DATA FROM SURFACE-MOUNTED PRESSURE SENSORS FOR VEHICLE ORIENTATION CONTROL
(FR) SYSTÈME ET PROCÉDÉ DE GUIDAGE DE VÉHICULE QUI UTILISE DES DONNÉES AÉRODYNAMIQUES PROVENANT DE CAPTEURS DE PRESSION MONTÉS EN SURFACE POUR UNE COMMANDE D'ORIENTATION DE VÉHICULE
Abstract:
(EN) A vehicle guidance system, including: sensors to detect a surface pressure distribution for a respective location of the corresponding sensor on a vehicle, respectively; and a controller to receive an initial value for a Mach number; and calculate a converged value for an angle of attack based on first surface pressure data from a first set of the sensors, and a converged sideslip angle value based on second surface pressure data from a second set of the sensors. The controller calculates a freestream dynamic pressure based on the initial Mach number, the converged angle of attack, and the converged sideslip angle value, and calculates a freestream pressure, and calculates a converged value for Mach number based on the freestream pressure and the freestream dynamic pressure. A flight control processor provides an output for adjusting an orientation of the vehicle based on the converged Mach number and the freestream pressure.
(FR) La présente invention concerne un système de guidage de véhicule, comprenant : des capteurs destinés à détecter une distribution de pression de surface pour un emplacement respectif du capteur correspondant sur un véhicule, respectivement ; et un dispositif de commande destiné à recevoir une valeur initiale pour un nombre de Mach ; et à calculer une valeur convergente pour un angle d'attaque sur la base de premières données de pression de surface provenant d'un premier ensemble de capteurs, et une valeur d'angle de dérapage convergente sur la base de secondes données de pression de surface provenant d'un second ensemble de capteurs. Le dispositif de commande calcule une pression dynamique en écoulement libre sur la base du nombre de Mach initial, de l'angle d'attaque convergent et de la valeur d'angle de dérapage convergente et calcule une pression en écoulement libre et calcule une valeur convergente pour le nombre de Mach sur la base de la pression en écoulement libre et de la pression dynamique en écoulement libre. Un processeur de commande de vol fournit une sortie pour ajuster une orientation du véhicule sur la base du nombre de Mach convergent et de la pression en écoulement libre.
