Patent ID: 8606434

Claim:
A regulator device for a helicopter wherein said helicopter is configured to carry an external load suspended from the helicopter in a direction of the ground on at least one supporting cable, comprising: at least one load oscillation recording unit for recording an oscillating movement of the external load in lateral and longitudinal directions with respect to a longitudinal axis of the helicopter; and one or more regulators which convert detected variables for the oscillating movement from said at least one load oscillation recording unit to a geodetic coordinate system, and generate closed-loop control signals as a function of the variables converted to the geodetic coordinate system for the oscillating movement of the external load, wherein said closed-loop control signals are a function of a mass (m L ) of the external load and a length (I s ) of the at least one supporting cable as parameters, and wherein said closed-loop control signals are applied to open-loop control signals for controlling flight of the helicopter.
