| 摘要: |
| 本文是“可调汽蚀文氏管”课题研究的阶段报告。 为了提高变推力发动机的控制精度，要采用带有特殊型面调节锥的线性可调汽蚀文氏管。本文证明了这种调节锥的形状应为一旋转抛物面，并得到了实验验证，也给出了这种使流量与调节锥行程为线性关系的文氏管之设计方法。为了便于设计，对参数间的关系及有关的问题也进行了讨论。 本文可供从事变推力液体火箭发动机和文氏管流量计的研究工作者参考。 |

| On Linear Throttling Cavitation Venturi |

| Abstract: |
| This paper is a phase report of the study concerning the subject"Throttling Cavitation Venturi".
To improve controle accuracy of the throttling engine，the linear throttling cavitation Venturi with a movable，specially shaped part is used. In our work，the shape of the movable part has been verified to be a rotational paraboloid，which has been proved by tests. The technique to design such a Venturi which makes the relationship between the f1ow rate and the moving distance be linear is presented. For the convenience of designing，some relations between parameters are given and Some problems concerned are discussed.
This report may be a reference for those who are engaged in the development of variable-thrust liquid propellant rocket engines and liquid Venturi f1owmeters. |
