| 摘要: |
| 本文基于梁弯曲变形的小挠度线性理论，提出了半挠性喷管挠性板弹性曲线的计算方法。并对挠性板弹性曲线与气动力学给出的型面进行了对比研究，两者吻合得校好，研究表明，结构设计中撑杆合理布局，是影响匹配的关键问题，足应引起设计者的重视。 |

| Abstract: |
| A method of calculating elastic curve for semiflexible plate wind tunnel nozzle has been presented，based on the linear theory of small deflection of beam deformation，in this paper. In light of the match results of curvature between flexible plate calculated and aerodynamic contour，the reasonable arrangment of jacks on the plate，which has an obvious effect on the curvature match，is of vital importance. So the structure designer of flexible nozzle should be cautious of it. |
