【 摘 要 】

The article is about design of the active aircraft control sidestick. The disadvantage of the known frame constructions, apart from the large dimensions, is the difference in the dynamic characteristics of the channels when using the same actuators, because the mass of a frame mounted actuator is the load for a fixed base mounted actuator. As a result the kinematic scheme of an active control sidestick which don't use a frame is offered. The frameless scheme contains two identical actuators mounted on the fixed base, at that the interference of channels is excluded. The derivation of the actuator's gear ratio is given. It is shown that this dependence between the rotation angle of the actuator output shaft and the handgrip deflection angle is of a sinusoidal type and that it is close to linear in the range of the handgrip operating angle.
