| 摘要 |
The invention relates to a device (1) for controlling the setting of the blades (2) of a rotor (3) of a propeller, including a radial shaft (6), the rotation of which modifies the setting of the blade (2), a main spring (13), a first end (14) of which is connected to the rotor (3) and a second end (15) of which is connected to a part (8, 10) having an axial movement which drives the rotation of the radial shaft, and has a movement, the travel of which is offset relative to the first end in a direction (7) that is orthogonal to the axial direction (5), the main spring exerting a resilient force which aims to move the parts toward a position in which the cord of the profile of the blade is orthogonal to the plane of rotation of the propeller, in the absence of part control by means of a jack. |

1. A control device (1) for the blade angle of the blades (2) of a rotor (3) of a propeller (4), comprising:
a radial shaft (6) whereof the rotation modifies the blade angle of the blade (2), pieces (8, 10) capable of being displaced jointly according to an axial direction (5) of the device (1), so as to cause rotation of the radial shaft (6), at least one actuator (12) controlling displacement of the pieces (8, 10) according to the axial direction (5);characterized in that it comprises:
at least one main spring (13) with a first end (14) connected to the rotor (3), and with a second end (15) connected to one of the pieces (8, 10), the second end (15) presenting a displacement with a course which is shifted relatively to the first end (14) according to a direction (7) orthogonal to the axial direction (5), the main spring (13) exerting resilient force tending to displace the pieces (8, 10) towards a position in which the cord (16) of the profile of the blade (2) is orthogonal to the plane of rotation of the propeller (4), in the absence of control of the pieces (8, 10) by the actuator (12). |
