The invention relates to a contra-rotating propeller system (1) for the turbine engine of an aircraft that comprises first and second propellers (6, 8) each including a control system (26, 56) for setting the blades, the latter including rotary actuation means (38, 68) for sliding a member (28, 58) in order to move the blades at an attack angle. According to the invention, the system also includes a declutchable means (72) for connecting in rotation the rotary actuation means (38, 68), wherein the system is designed so that, when said means (72) is clutched, a relative rotation speed is generated between the members (28, 58) and their associated rotary actuation means (38, 68), thereby moving the blades (6a, 6b) into a neutral feathering position.
Système d'hélices contrarotatives (1) pour turbomachine d'aéronef, comprenant une première et une seconde hélices (6, 8) disposant chacune d'un système de commande de calage (26, 56) des pales, ce dernier comprenant des moyens rotatifs d'actionnement (38, 68) permettant de faire coulisser un organe (28, 58) afin de déplacer les pales en incidence. Selon l'invention, le système comprend également des moyens débrayables (72) permettant de rendre solidaires en rotation les moyens rotatifs d'actionnement (38, 68), le système étant conçu de sorte que lorsque ces moyens (72) sont embrayés, une vitesse de rotation relative se crée entre les organes (28, 58) et leur moyens rotatifs d'actionnement associés (38, 68), amenant les pales (6a, 6b) dans leur position neutre de mise en drapeau.
