USING OF ACCELERATION SIGNALS IN CONTROL LAWS FOR OSCILLATION DAMPING OF LOADS TRANSPORTED BY HELICOPTER SLING LOADING
This article presents analytic expressions using the example of the helicopter lateral movement analysis with a helicopter sling loading. These expressions make it possible to form the estimation of the sling load deflection angle from the objective vertical using only measurements of the roll and pitch attitudes and acceleration vector components. The materials of mathematical modeling are presented, which confirmed the control law performance of the sling load oscillation damping system when onboard sensors measuring directly the sling load deflection angle are absent.
