Abstract: A gymballess, two axis rate gyroscope in which an inertia rotor is keyed on the electric motor shaft. The motor shaft comprises a flexible part (flexure shaft) adapted to flex upon precession of the inertia rotor in consequence of an angular velocity input around either of two axes normal to each other and both normal to the rotor spin axis, and an end portion extending beyond the inertia rotor in a direction away from the electric motor (delfector). The gyroscope further comprises a non-contacting measuring device in association with the deflector for detecting any deflection thereof.
