一、前言 研究分析动态压力进气畸变的早期方法为确定性方法(Determinate Method),其优点在于准确可靠。然而用确定性法处理分析动态压力进气畸变是一个极为繁重的计算过程,耗资费时,故多用于定型阶段的进气道与发动机的最后匹配性校核中。国外从70年代初开始研究用统计方法来预测发动机进口的最大瞬时压力畸变,致力于在工程运用上 I. INTRODUCTION The early method of analyzing the dynamic pressure inlet distortion was deterministic (Determinate Method), which has the advantage of being accurate and reliable. However, the deterministic method to deal with the dynamic pressure intake air distortion is a very arduous calculation process, it is costly and time-consuming, it is mostly used in the final phase of the intake air intake and engine consistency check. Abroad from the early 1970s began to study the use of statistical methods to predict the maximum instantaneous pressure engine inlet distortion, is committed to the engineering application
