Systems and Methods Involving Reduced Thermo-Acoustic Coupling of Gas Turbine Engine Augmentors

摘要

Systems and methods reducing thermo-acoustic coupling of a gas turbine engine augmentors are provided. In this regard, a representative method includes: determining acoustic resonances and heat release phase relationships associated with the augmentor; and determining relative axial positions of a fuel injector and a flame holder of the augmentor that result in reduced thermo-acoustic coupling of the augmentor during operation.
