ABSTRACT:
A stall recovery system for a ram air turbine (RAT) that supplements the operation of a volume fuse in the hydraulic system of the RAT by sensing a stall condition as the combination of low pressure at less than maximum flow and reducing RAT load torque after the sensed stall so that stall recovery is possible.
