Abstract
Juxtaposed recirculation zones for the pilot in the burner of an augmentor for a gas turbine engine is created by fabricating the engine's tail cone in two components and including an annular gap defined between the juncture of both components that injects a stream of cooling air radially into the augmentor's gas path for eliminating or minimizing screeching in the augmentor.
