ABSTRACT:
An electromagnetically interference-proof flight control device having an hydraulic positioning drive for a control surface, the position of which is to be influenced. Provided are at least one signal line for feeding in optical control signals, at least one hydraulic pressure line and a return line, an electrohydraulic valve arrangement which precedes the hydraulic positioning drive and is connected to the hydraulic pressure line, an optical-electronic converter which converts the optical control signals into corresponding electronic signals for the electrohydraulic valve arrangement and a hydraulic-electric energy converter. The hydraulic-electric energy converter serves as an electric energy source for the opto-electronic converter and for addressing the electrohydraulic valve arrangement. To accomplish the hydraulic-electric energy conversion for the internal power supply in a manner as interference-free and wear-free as possible, the hydraulic-electric energy converter comprises a fluidic oscillator and one or more piezoelectric elements acted upon by the former with periodically variable pressure.
