an anemometric stabilizer consists of asmall surface A (Fig. 104), which can go forward or back-ward under the action of the air thrust R, and under thereaction of a spring S. The air thrust R, is proportional tothe square of the speed. When the relative speed is equalto the normal one, a certain… … Fig. 104. small disk will go forward under the spring reaction.Through rod S, these movements control a proper servo-motor which maneuvers the elevator so as to put the air-plane into a climbing path when the speed increases, andinto a descending path when the speed decreases. Such functioning is…
