INVESTMENT COMBUSTION CHAMBER, ESPECIALLY INVESTMENT ANNULAL COMBUSTION CHAMBER FOR GAS TURBINE PROPELLING MECHANISMS AT LEAST WITH A FLAME TUBE WALL FILM COOLING SYSTEM.

摘要

THE REVERSIBLE COMBUSTION CHAMBER HAS AN ANNULAR CHAMBER, ENCLOSED BETWEEN THE SECTIONS OF THE WALL OF THE FIRE TUBE. THIS ANNULAR CHAMBER IS SUPPLIED WITH REFRIGERATING AIR FROM AN EXTERNAL ANNULAR CHANNEL (ADMITTING SECONDARY AIR IN THE DIRECTION OF THE MAIN CURRENT IN THE FIRE TUBE), SO THAT IT IS EXPELLED IN THE FORM OF FILM AGAINST A WALL CONTAINING THE TUBE , IN THE OPPOSITE DIRECTION OF CURRENT. IN ORDER FOR THE REFRIGERATING FILM TO BE DISTRIBUTED EVENLY ALONG THE ENTIRE PERIMETER AND WITH A CONSIDERABLE LENGTH, THE RING CHAMBER MUST BE FORMED TOWARD THE LONGITUDINAL DIRECTION OF THE COMBUSTION CHAMBER IN A FLAT-ELLIPTICAL WAY. THEREFORE, A PART OF THE REFRIGERANT AIR PROVIDED, TOGETHER WITH THE AIR COLLECTOR DRILLS (WHICH MAKE A RADIAL DAMAGE AND AT THE TOP TANGENTIALLY AT THE END OF THE SECONDARY CURRENT - FROM THE ANNULAR CHAMBER) WILL PRODUCE A TORBULAR REBUILD. , QUECORRERA ALONG THE ELLIPTICAL CONTOURS OF THE ANNULAR CHAMBER. THROUGH THIS SWIRL OF RECYCLING, THE HOMOGENEITY OF THE MAIN COOLING AIR STREAM WILL BE ACHIEVED, PROVIDED THROUGH THE AIR COLLECTING DRILLS AND BENDED BY 90 IN THE DIRECTION OF THE MAIN STREAM OF THE FIRE TUBE.
