An integrating angular accelerometer for measuring angular rate of a rotating body has a stationary cylindrical inertial mass supported by a low drag hydrostatic bearing concentrically in a housing rotatable relative thereto and filled with a viscous fluid. An annular channel of laminar dimensions is formed between the inertial mass and housing and a vane is arranged in the channel to block fluid flow caused by rotation of the housing relative to the inertial mass. The differential pressure in the channel at opposite sides of the vane provides a signal corresponding to the rate of rotation of the housing relative to the inertial mass. |
