| 摘要: |
| 提出了基于B-Spline曲线和特征线方法的超声速型面可控喷管设计方法，通过设置喷管轴向马赫数分布可以灵活地调整喷管的型面形状。数值验证结果表明，该方法不仅可以设计出高品质的喷管出口流场，而且能够实现喷管型面的灵活调整，可以获得长度与最短长度喷管一致，但流场品质更优的喷管。 |

| Abstract: |
| A designing method of supersonic nozzle with controllable contour based on B-Spline curve and characteristic line algorithm is proposed. The contour of the nozzle was adjusted by assigning the distribution of Mach number on the nozzle’s axis. The reliability of the designing method was validated by numerical simulation, which shows that the outflow of the nozzle with high quality can be produced and the contour can be adjusted freely. The result also shows that the nozzle designed by the proposed method can produce better flow than the minimal length nozzle(MLN) with the same length. |
