扰动对超声速进气道起动状态影响的数值模拟

of disturbing on starting state of ramjet engine inlet

摘要:

对超声速冲压发动机进气道—喉道段进行了二维稳态流场数值模拟,给出了反压与攻角变化对冲压发动机进气道起动状态影响的数值模拟结果。得到不同反压及不同攻角下进气道—喉道段流场,分析了起动与不起动时进气道—喉道段壁面静压分布特性。

Abstract:

The prevailing software numerically simulates a 2-D internal steady flow of the ramjet inlet-isolator; the numerical simulation results of the state of start in the ramjet inlet are presented. The static pressure contours of the ramjet inlet-isolator under different backpressure and angle of attack are given. The distribution of static pressure of the inlet-isolator is analyzed when the inlet is started and unstarted.
