Mixed flow swirl augmentor for turbofan engine

摘要

An augmentor in a turbofan jet engine utilizes a crossover chute assembly to direct portions of the bypass fan stream inwardly and portions of the hot core stream outwardly into alternating radial zones of fan and core stream flow; and also annularizes a portion of the core stream around those zones. A plurality of angularly positionable radial vanes causes rotational swirl of the radial zones in one direction to produce buoyant "g" forces that effect rapid inward propagation of a flame front from the annularized zone.
