【摘要】 用特征面参数化方法数值模拟了喷管的非对称流场，研究了当总温、总压在喷管超声速段入口截面分布不均匀时，所引起的锥型喷管的推力偏心特性，得到了锥型喷管在不同扩张角和不同总温、总压分布时，喷管侧向推力分量沿轴向的变化及其零点位置在轴线上的分布规律．对微推偏喷管的设计具有重要参考价值．更多还原

【Abstract】 In this paper, the isentropic, non symmetrical flow fields in nozzle are numerically simulated by three dimensional method of characteristics. The thrust misalignment in rocket nozzle is investigated for the situation where the stagnation temperature and stagnation pressure are disturbed non symmetrically in the supersonic region of the nozzle. Distributions of side force and zero points along the axis of nozzle are presented for different distribution of stagnation temperature and stagnation pressure of conical nozzles.更多还原
