The present invention relates to a trim actuator actuating system having two separate hydraulic power supply systems, through which it is possible for the first time to use a hydraulic linear actuator as a trimmable horizontal stabilizer actuator in an aircraft. The at least one hydraulic linear actuator is coupled to the first power supply system in such a way that it applies hydraulic power to the linear actuator during normal operation. In order to ensure the application of pressure to the hydraulic linear actuator in case of breakdown, in such a case, the pressure application to the hydraulic linear actuator is maintained with the aid of the second hydraulic power supply system.
L~invention concerne un système de commande d~actionneur de compensation comportant deux systèmes d~alimentation hydrauliques distincts permettant l~utilisation inédite, dans un aéronef, d~un actionneur hydraulique linéaire comme actionneur d~empennage horizontal compensable. L~actionneur hydraulique linéaire est couplé au premier système d~alimentation hydraulique de manière à fournir de l~énergie hydraulique à l~actionneur linéaire en fonctionnement normal. Le deuxième système d~alimentation hydraulique permet de maintenir la pression appliquée à l~actionneur hydraulique linéaire en cas de défaillance du premier système d~alimentation hydraulique.
