CIRCULAR COMBUSTION CHAMBER OF GAS TURBINE ENGINE Russian patent published in 2013 - IPC F23R3/50 F23R3/60 

FIELD: engines and pumps.

SUBSTANCE: circular combustion chamber of a gas turbine engine comprises an outer wall and an inner wall connected by a wall forming a chamber base. These walls limit furnace spaces, the axis of which is inclined relative to the chamber axis. In the wall of the chamber base, having the form of the truncated cone, there are holes drilled, design for fuel injection systems. Planes of holes are perpendicular to axes of these furnace spaces. Deflectors of thermal protection aligned relative to each hole comprise a flat collar, by means of which they rest against a section of a flat surface around the circumference of holes. The walls of the chamber base is made of one sheet along the perimetre of the combustion chamber and is represented by the sequence of bordering flat faces, forming one common board. Each face has a hole. The collar of the deflectors rests against the bearing surface of the faces.

EFFECT: provision of deflectors fixation on a wall of a combustion chamber with a small distance between holes for fuel injection systems.
