Control rod device

摘要

A control rod configuration for adjusting a position of a rotor blade of a helicopter. The control rod configuration includes a control rod which has a bearing eye, adjacent the swash plate, which is penetrated by an axle shaft which has a bearing supported by a bearing bracket. The control rod configuration, which can be simply constructed and is less susceptible to malfunction, has an eccentric with its pivotable bearing in the bearing bracket and which is provided between the bearing bracket and the bearing eye. In addition, a method in which a rotor blade of a helicopter has an assigned control rod which is supported by an axle shaft with a bearing in the bearing bracket which is mounted to the swash plate so as to enable adjustment of the control rod by pivoting the axle shaft during flight.

主权项

1. A control rod configuration, for adjusting a rotor blade of a helicopter, comprising:
a control rod (12) having a swash plate side bearing eye (11), at one end, which is penetrated by an axle body (5), the swash plate side bearing eye of the control rod defining a longitudinal axis, the axle body (5) being rotationally supported by a bearing in a bearing bracket (2) such that the axle body is rotatable in the bearing bracket about a rotational axis, and an eccentric (8), which is pivotable in the bearing bracket (2), being arranged between the bearing bracket (2) and the swash plate side bearing eye (11), the eccentric having a central axis that is offset from the rotational axis of the axle body and is coaxial with the longitudinal axis of the swash plate bearing eye of the control rod.
