| 中文摘要: |
| 为解决航空发动机可调喷管液压作动筒工作腔流量偏小问题，对作动筒复杂双油路腔开展了CFD 数值仿真分析，阐明
了作动筒流量偏小原因，提出了增大流量的措施并仿真分析了改进效果。计算结果表明：仿真流量由465.5 mL/s 增大到539 mL/s，
增大了73.5 mL/s;流量实测值由443 mL/s 增大到507 mL/s，满足设计要求，最终通过作动筒流量试验验证。 |
| 英文摘要: |
| In order to solve the problem of small flow in the working chamber of regulated hydraulic nozzle actuator of aeroengine，
CFD numerical simulation was carried out for the complex double oil cavity of actuating cylinder，and the reasons for the small flow of
actuating cylinder were expounded. The measures to increase the flow were put forward and the improvement effect was simulated and
analyzed. The results show that the simulation flow increases from 465.5 mL/s to 539mL/s and increased by 73.5mL/s；The measured flow
which meets the design requirements is increased from 443mL/s to 507mL/s. Finally the flow test of the actuating cylinder is verified. |
