base bleed meaning in English
底部放气
Examples
- Numerical investigation of 3 - d turbulet flow fields for supersonic flying base bleed projectile
超声速飞行底部排气弹三维湍流流场数值模拟 - The doppler radar data processing of the first flight segment trajectory for the rocket - assisted and base bleed projectiles
复合增程弹起始飞行段弹道测速数据处理方法 - The base bleed has two contrary action of providing energy and ejection , and it can weaken the effect of lateral jet upon base flow
底喷流动具有添质加能和引射两种相反作用，并能消弱侧喷流对弹丸底部流动的影响。 - The lateral jets are caused to incline to the direction of rotating free flow and to weaken the effect upon base flow . furthermore , the spinning effect upon lateral jet is much stronger than that upon base bleed
与无旋转情况对比表明，旋转对弹丸侧喷流以及底部流动均有影响，高速旋转导致侧喷射流向旋转来流方向倾斜，并减弱其对弹底流动的引射。 - Without spinning or attack angle , the three dimensional interaction flowfield over projectile with lateral jets is numerically simulated successfully , and unified interaction flowfield with lateral jets and base bleed is also calculated
在无旋转、无攻角条件下完成了弹丸侧喷三维干扰湍流流场数值模拟，并完成了弹丸底喷流-侧喷流共同干扰流场的一体化计算。
