Abstract : The present invention is directed to an integrating angular accelerometer which has a neutrally bouyant mass, thereby eliminating the detrimental effect of high shock and vibration loads. The accelerometer includes a housing and an inertial mass positioned in the housing, arranged for relative rotation with respect to the housing. An annular channel is provided between the housing and the inertial mass, located about the acceleration sensitive axis and dimensioned to cause fluid flow upon relative rotation of the housing and inertial mass in the direction of relative rotation. The fluid contained within the channel is a viscous fluid having a density equal to that of the inertial mass so as to achieve a neutral bouyancy of the inertial mass. A splitter for blocking fluid flow in the channel is provided so as to produce a differential pressure which corresponds to the relative angular rotation of the inertial mass and housing. A transducer is provided for converting the differential pressure into an electrical signal corresponding thereto. (Author)
