摘要
采用计算流体力学的方法计算了水下潜器主体在正弦和线性两种转艏方式下导管螺旋桨水动力性能,计算结果表明:当水下潜器主体从不同的方向摆动至同一位置时,导管螺旋桨进速、轴向速度和轴向诱导速度都不一样,逆时针方向转艏时大于顺时针方向;水下潜器按正弦转艏时,导管螺旋桨盘后轴向速度以及轴向诱导速度均大于按线性转艏的情况;潜器主体正弦摆动时,导管螺旋桨的推力大于线性摆动时,且均小于固定情况.
By using the method of computational fluid mechanics under sinusoidal and linear body in two kinds of yawing mode of ducted propeller hydrodynamic performance of water was calculated,the results show that when the underwater vehicle body from different direction swing to the same position,the ducted propeller into velocity,axial velocity and axial induced velocity are not the same,inverse when the bow is larger than clockwise clockwise direction; underwater sinusoidally yawing,ducted propeller after axial velocity and axial induced velocity is greater than the yawing according to the linear case; submersible body sine swing,propeller thrust greater than linear swing,and less than the fixed.
