| 摘 要： | 采用代数方法、局部变形技术及快速动态弹性变形技术生成三维翼/体组合的贴体动态网格。用时间精确近似因式分解差分方法求解守恒型非定常全位势方程。考虑附面层影响，通过粘/位迭代得到跨音速翼/体的非定常气动力。所得结果与实验数据相比相当吻合。

| Abstract: | Algebraic methods and rapid deforming techniques are used to generate three-dimensional boundary-fitted dynamic grids for assemblies. The conservative full-potential equation is solved by a time-accurate approximate factorization algorithm and internal Newton iterations. An integral boundary layer method based on the dissipation integral is used to account for viscous effects. The computational results about unsteady transonic forces on wings, bodies and control surfaces are in agreement with experimental data. |
