ABSTRACT:
The steering or control force for operating a steering column in an aircraft, especially in a rotary wing aircraft, is stabilized. The steering column influences through an articulated steering or control linkage the elevator assembly or the rotor blade adjustment, whereby a signal is employed which is dependent on the measured flight speed. It is necessary to signal to the pilot at all times how the steering column must be moved. Such signalling must be definite and free of any disturbing influences and the pilot must receive such signalling through the steering column manual force which is a force reacting to the operation of the steering column. For this purpose a speed dependent signal is supplied to a servomotor. This signal rises with the flight speed at least above a preselectable threshold value. The servomotor in turn controls the tensioning state of a spring which is pivoted at one end to the steering column and at the other end to the displacement member of the servomotor. Preferably, the point of articulation between the spring and the steering column is located approximately opposite the point of articulation between the steering column and the steering or control linkage. Additionally, a feedback signal derived from sensing the displacement caused by the servomotor is added to the speed dependent signal. The feedback signal varies in the same sense as the displacement caused by the servomotor and serves to achieve proportionality between the signal S and said displacement.
