ABSTRACT:
A turning indicator for indicating the turning direction and the turning speed of course changes of a ship or an aircraft, in which an electromotor is movably mounted between two supports of a carrier. An axle of the carrier is fixedly connected with the upper end of a leaf spring, the lower end of which is loosely guided. A measuring bridge is mounted on the leaf spring which is connected to an indicating device via an amplifier circuit. The measuring bridge can be supplied with direct current and the starting signal of the measuring bridge is also in the form of direct current which is positive or negative depending on the direction of deflection of the leaf spring, and thus indicates a measure of the turning direction, whereas the magnitude of the deflection of the leaf spring is a measure of the intensity of the starting signal and thus a measure of the turning speed.
