Description
A novel Integrated Predictive and Analysis Computational Technology (IPACT) for the critically needed solution of the sever high and low frequency screech instability problems in military Air Force (AF) flight propulsion systems such as afterburners will be further developed, validated , demonstrated, and incorporated into AF design and testing tools. Since current military and industry "cut and try" empirical approaches involving changes to afterburners flame-holders, chamber shape, fuel injection, velocity profiles, and flame piloting have proven inadequate. In such afterburner applications, the pressure, mechanical vibration, and, heat loads resulting from combustion screech instability, superimposed on the normal loading, are usually destructive and must be avoided at any cost.
