| 摘 要： | 针对航空单级增压泵在发动机低转速下供油压力不足的问题,给出了一种采用径向串联方式的两级旋涡组合泵设计方法.该方法首先使用经验系数法对旋涡组合泵进行初步结构参数设计.其次通过计算机数值模拟方法反复迭代优化出旋涡组合泵的最终结构参数.最后采用二次多项式拟合对两级旋涡组合泵的流量-扬程性能进行了预测.仿真结果表明:所设计的两级旋涡组合泵满足设计要求,达到了预期设计指标.

| Abstract: | Point to deficiency oil supply pressure of booster pump at low aeroengine speeds,a two grade combination vortex pump design method with radial series structure is give.In this method,the preliminary structural parameters of the vortex pump are designed by using the empirical coefficient method.Then the final structure parameters are obtained by numerical optimization.Finally,the flow-lift performance of the combination vortex pump is predicted by quadratic polynomial fit.The simulation results show that: the two grade combination vortex pump is satisfied the design requirements. |
