A method for operating a parking lock system () with a parking interlock gear () is provided. The parking lock system () also includes a parking pawl () insertable with an insertion section () in one of recesses () of the parking interlock gear () in order to interlock the parking interlock gear (), a parking lock actuator () for the parking pawl (), and a parking lock sensor () for detecting an absolute rotation angle position of the parking interlock gear (). The method includes detecting an absolute rotation angle position of the parking interlock gear () and comparing the detected absolute rotation angle position with a reference rotation angle position. When the particular absolute rotation angle position is situated behind the reference rotation angle position as viewed in the particular direction of rotation of the parking interlock gear (), a rattling process of the parking pawl () is detected.

Method and control unit for operating a parking lock system

An actuator for aviation applications, in particular for adjusting rotor blades in a helicopter, may include an electromechanical drive assembly connected to an output drive via a downstream transmission, where the drive assembly is divided into sub-drives that can be operated independently, and where at least two sub-drives are spatially separated from one another in that the transmission is placed between these sub-drives. The transmission may include at least two harmonic gearings coupled to one another by at least one first coupling element, where a first harmonic gearing is located inside a non-rotating first housing, where a second harmonic gearing is located inside a rotating second housing, and where the second housing is connected to the output drive.

Actuator for aviation applications

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.
