Stabilizer
First Claim
1. Stabilizer for rotorcraft which carry one hanging sling load on at least one supporting cable:
- comprising;
at least one sling load pendulum motion detecting unit (S2) for detecting pendulum motion of the sling load; and
a working range determination unit (S3) to determine a free working range in which the rotorcraft with sling load can move without collision, andwherein the stabilizer generates the control signals (R) in dependency of a detected pendulum motion of the sling load and in dependency of a determined working range, andwherein the sling load pendulum motion detecting unit (S2) for detects the pendulum motion of the sling load in a lateral and a longitudinal direction in relation to a longitudinal axis of the rotorcraftwherein the stabilizer generates control signals (R) which are applied or modulated onto flight control signals of the rotorcraft for damping pendulum motion of the sling load.

Abstract
A rotary aircraft which carries a hanging sling load on at least one support cable, benefits from a stabilizer which generates control signals R to be applied or modulated onto the flight control of the aircraft. At least one sling load pendulum motion detecting unit provides the stabilizer with data on the pendulum motion of the sling load. Additionally, the stabilizer is set up with a working range determination unit S3 for determining the space where free movement is possible in which the rotary aircraft with sling load can move without collision. The stabilizer generates control signals R in dependency of the determined pendulum motion of the sling load and the determined working range.
