Combustion chamber construction

Abstract

Abstract THE SUBJECT COMBUSTION CHAMBER CONSTRUCTION HAS AN OUTER CASING ENCLOSING AN INNER CASING TO FORM AN ANNULAR COMBUSTION CHAMBER WITH AN AIR PLENUM OR PASSAGE EXTENDING ALONG THE OUTSIDE, RADIALLY INWARDLY AT THE REAR END, AND AXIALLY ALONG THE INNER SIDE. AIR FROM THE ENGINE COMPRESSOR ENTERS THE PLENUM AT THE FRONT END AND FLOWS THROUGH THE PASSAGE INTO THE COMBUSTION CHAMBER THROUGH OPENINGS IN THE INNER WALL THEREOF, SUCH AIR THEN FLOWING TANGENTIALLY FROM THE INNER WALL TO FORM A TOROIDAL FLOW PATTERN. FUEL IS SPRAYED INTO COMBUSTION CHAMBER FROM TANGENTIALLY DIRECTED JETS TO MIX AND BURN WITH THE AIR IN THE TOROIDAL FLOW PATTERN, THE RESULTING GASES DISCHARGING FROM THE CHAMBER VIA AN ANNULAR RADIALLY INWARDLY DIRECTED NOZZLE ADJACENT THE AIR-INLET. THE TOROIDAL FLOW PATTERN IN THE ANNULAR CHAMBER PROLONGS THE AIR/FUEL MIXING AND BURNING PERIOD.
