Abstract:

An augmentor in a turbofan jet engine utilized 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 zoned.
