| 摘 要： | 对带有内埋武器舱盖的载机,采用结构重叠网格方法保证各舱盖与载机网格质量,通过求解三维定常、非定常Navier-Stokes方程,得到内埋武器舱盖开启过程的静态、动态复杂流场,分析了内埋舱盖开启过程中其内外壁的气动特性,通过分析发现内外壁分布压力变化各有特点,动态压力分布居于静态压力分布包络中,舱盖结构强度设计宜采取"动-静结合"方式。

| Abstract: | As for the aircraft with weapon cabin′s door,structured overlapping grids generated around each door and the aircraft can work well.Thorough solving 3-dimensional steady/ unsteady Navier-Stokes equations,the steady/unsteady and complicated flow field aroused by opening the interior weapon cabin′s door,is reached,the aerodynamic characteristics of the inside and outside of the door,is analyzed.The conclusions are as that：different distributed pressure on inside between outside wall,dynamic pressure included in static pressure,dynamic-static united idea feasible in design of structure intensity of cabin′s door. |
