ABSTRACT:
Rate of turn indicator for a nautical vessel, aircraft and the like indicating the rate of turn or swing in units such as degrees per unit of time from a particular course of travel. The indicator includes a magnetic gyro wheel including a flexible hub rotating about an axis in the same plane as the course of travel, and electromagnetic sensing coils receiving the deviations of strength of the electromagnetic field of the magnetic gyro wheel from an axis on turning from the course of travel. The magnetic gyro wheel includes a plurality of permanent magnets of alternating poles positioned about a circumferential axis of a circular member, and a flexible hub material affixed to the interior diameter of the circular member. The hub is affixed to an axially support shaft. The rate of turn indicator includes a meter connected to the electromagnetic sensing coils through electrical circuitry and a potentiometer for zeroing the meter where the meter indicates the rate of turn.
