ACTUATOR FOR CONTROLLING A FLIGHT CONTROL SURFACE

摘要

The invention relates to an actuator (4) for controlling a flight control surface (3) of an aircraft, comprising:—a primary route (5) comprising a first member (8) for generating a first torque, and a first drive shaft (10) having an end (18) able to be connected to the first member (8) and an end (19) able to be connected to the control surface (3),—a secondary route (6) comprising a second member (24) for generating a second torque and a second drive shaft (26) having an end (45) able to be connected to the second member (24) and an end (46) able to be connected to the control surface (3), in which actuator the second drive shaft (10) is hollow and extends around the first drive shaft (26).

主权项

1. An actuator for controlling a flight control surface of an aircraft, comprising:
a primary path comprising a first member for generating a first torque, and a first drive shaft having one end capable of being connected to the first member and one end capable of being connected to the control surface, the end of the first drive shaft capable of being connected to the control surface having first reliefs capable of cooperating with reliefs of the control surface to connect in rotation the first drive shaft and the control surface, a secondary path comprising a second member or generating a second torque and a second drive shaft having one end capable of being connected to the second member and one end capable of being connected to the control surface, the end of the second drive shaft capable of being connected to the control surface, having second reliefs capable of cooperating with reliefs of the control surface to connect in rotation the second drive shaft and the control surface, wherein the second drive shaft is hollow and extends around the first drive shaft.
