Design considerations for a flueric laminar jet angular rate sensor

This report presents experimental performance data for a laminar jet angular rate sensor (LJARS). An LJARS is a device in which a radially issuing laminar jet deflects relative to a rotating frame of reference causing a pressure differential that is proportional to angular rate. Both theory and data show that the output differential pressure is a linear function of applied angular rate. The report expands considerably on previous work by presenting numerous empirical guidelines for the design and the implementation of these devices. Methods for effecting suitable temperature and null offset compensation are discussed as are environmental temperature, and pressure effects. Finally, typical LJARS characteristics are summarized.
