<p>A hydraulic feel augmentation system for high speed helicopters in which a force is applied to the cyclic stick in direct proportion to the loading induced by movement of the stick. An unbalance in electrical load sensing inputs to twin pressure control valves generates hydraulic flow to deactivate force pistons and a damping force is then provided for the cyclic stick. The stick can be activated by the pilot against the damping force, and the system will not be activated until reset.</p> |
