Finite Element Analysis of the Drum-Shape Cavity Fluidic Gyroscope Sensitive Mechanism

Abstract:

Against the deflect that the existing fluidic gyroscope airflow channel structure was easy to cause the flocculating flow. This paper presented a kind of elliotic-drum flow cavity structure. Using the finite element method, calculated the flow field in the closed cavity at different angular velocity input. The results showed that the gas flow path of the main airflow distribution was streamlined, there did not form the vortex area which could reduce the energy additional losses, when the angular rate input changed, then the jet flow field distribution didnt keep equal and symmetrical, the jet speed difference at the hot sensitive wire changed with angular velocity, thus revealing the drum-shape cavity fluidic gyroscope sensitive mechanism.
