COMBUSTION CHAMBER COMPRISING HEAT-PROTECTIVE REFLECTORS OF CHAMBER BOTTOM AND GAS TURBINE ENGINE EQUIPPED WITH SUCH CHAMBER Russian patent published in 2013 - IPC F23R3/50 

FIELD: engines and pumps.

SUBSTANCE: circular combustion chamber of a gas turbine engine comprises inner and outer walls and a wall that connects these two walls and forms a chamber bottom. The chamber bottom wall is equipped with holes for fuel injection systems. Heat-protective reflectors are fixed on the wall. Reflectors contain a flat section of wall with a hole aligned by specified holes of the fuel injection systems, two longitudinal edges and two transverse edges. At least along one of the longitudinal edges the reflector comprises a tab, which continues the rear side of the reflector wall and forming a joint slab, leaving a gap along the specified edge for the edge of the adjacent reflector to ensure tightness of the joint between two adjacent edges of two reflectors. The specified tab is arranged at the distance from the chamber bottom wall, forming the space, where cooled air arrives via channels in the chamber bottom wall.

EFFECT: invention makes it possible to simultaneously provide for tightness between reflectors and cooling with an air jet in a narrow critical zone, which is located between holes of injection systems.
