A novel basic architecture for helicopter autopilots where the conventional fuselage attitude control function is turned into an airspeed control function without resorting to coupler technology. A known fraction of the flight control output signal (24S) is added to a standard fuselage attitude input (1S) and fed to each of the two pitch and roll channels, and the resulting signal (4S) has the new static and dynamic properties needed for the control loop to impart static speed stability to the helicopter throughout the flight envelope. Said novel architecture enables the conventional fuselage attitude signal (1S) to be replaced with an accelerometer signal. By displaying the signal (4S), in particular on a standard attitude indicator instrument (33), rapid changes in fuselage attitudes may be monitored and airspeeds may at the same time be controlled.
L'invention concerne une nouvelle architecture de base pour les pilotes automatiques d'hélicoptères, transformant l'objectif clas- sique de tenue d'assiette de fuselage en objectif de tenue de vitesse- air, sans recourir aux techniques des coupleurs. Sur chacune des deux chaînes tangage et roulis, on injecte, en sommation avec l'entrée standard (1S) d'assiette de fuselage une fraction connue du signal de sortie (24S) de la commande de vol. Le signal (4S) ainsi formé possède les propriétés statiques et dynamiques nouvelles requises pour que la boucle de pilotage rende l'hélicoptère statiquement stable en vitesse dans tout le domaine de vol. La nouvelle architecture per- met de substituer un signal d'accéléromètre au signal (1S) classique d'assiette de fuselage. La visualisation du signal (4S), en particulier sur un instrument de type standard "horizon artificiel" (33), permet simultanément la surveillance des variations rapides des assiettes de fuselage et le pilotage des vitesses air.
