摘要

A comprehensive collective axis limit avoidance system for Carefree Maneuvering in rotorcraft has beenrnevaluated. The system is designed to simultaneously prevent exceedances of the continuous and transientrntransmission torque limits, transient RPM limit and engine temperature torque limit. The system is also used to assistrnin OEI recovery and autorotation. A dynamic trim estimation algorithm using offline trained neuralrnnetwork/polynomial curve-fit for torque prediction is used to calculate constraints on the collective stick forrncontinuous torque limits. Different configurations of torque prediction are evaluated for possible implementation inrnexisting and future rotorcraft. A peak response estimation algorithm based on linear model of aircraft dynamics isrnused for transient limit prediction. The system is tested with a non-real time simulation model of the UH-60A BlackrnHawk helicopter. A limit over-ride approach for stick limiting is evaluated which combines the precision of AFCSrnlimiting with the limit over-ride capability of tactile cueing. The entire system is evaluated for different non-realrntime maneuvers.
