Abstract
Abstract ZONE. THE INJECTORS ARE RADIALLY ALIGNED ON INTEGRAL MOUNTING STRUTS. ALTERNATE ALIGNMENTS AND SHAPES OF INJECTORS ARE SHOWN. A FUEL INJECTOR IS SHOWN HAVING A HEMISPHERICAL CUP WHICH OPENS DOWNSTREAM INTO A COMBUSTION ZONE. A BAFFLE PLATE EXTENDS OUTWARDLY OF THE CUP. AIR ENTERING TANGENTIAL SLOTSS CREATES AN AXIAL VORTEX WHICH BREAKES UP FLUID INTRODUCED TANGENTIALLY AT THE REAR OF THE CUP. AIR FLOWING OVER THE EDGES OF THE CUP CREATES A PERIPHERAL VORTEX. THE COMBINED ACTION OF THESE VORTICES PROVIDES A STABLE FLAME FRONT OF SHORT AXIAL LENGTH. THE FLUID INJECTORS ARE DISPOSED IN THREE CIRCUMFERENTIAL ROWS AROUND AN ANNULAR COMBUSTION
