Title:
VECTOR LIMITING OF A ROTOR CONTROL VOLUME
Document Type and Number:
WIPO Patent Application WO/2016/039834
Kind Code:
A3
Abstract:
A method and system for vector limiting of a rotor control volume for a helicopter with one or more controllers configured to issue a displacement command during a flight maneuver and a computer operably connected to the one or more controllers and configured to receive signals with a processor indicative of a displacement command for a rotor during a flight maneuver; determine with the processor an origination point for a command vector in a reference frame; determine with the processor the command vector in the reference frame; determine with the processor a command radius for the command vector; compare with the processor the command radius with values of estimated command radii in a look-up table; and determine with the processor a control volume limited command in response to the comparing of the command radius with the estimated command radius.
