Lo-Frequency Augmentor Instability Investigation Computer Program User's Manual.

摘要

This report describes the computer code and the models developed to form the computer code used to analyze low frequency augmentor instability (rumble). Rumble occurs mainly at high fuel-air ratios and at flight Mach numbers and altitudes where low duct inlet air temperatures and pressures exist. The model was developed in conjunction with and checked by two experimental programs.
