This　paper　reports　structure　design,　sensing　principle　and　numerical　simulation　of　a　novel　gyroscope　based　on　multidirectional　jet　flow　generator.　The　finite　element　analysis　method　and　COMSOL　Multiphysics　software　were　used　to　calculate　the　airflow　field　distribution　and　motion　feature　in　the　generator.　The　results　indicate　that:　(1)　When　the　angular　velocity　ranged　from　0　to　60rad/s　along　the　Z　axis　was　applied,　the　deflection　of　flow　is　increasingly　obvious　with　the　increasing　of　angular　velocity　and　linearly　proportional　to　applied　angular　velocity.　(2)　The　distance　between　hotwires　and　nozzle　is　L-x=1.4-1.6mm　and　that　between　hotwires　and　central　axis　of　nozzle　is　L-Y=0.33-0.35mm,　respectively.
