TURBOMACHINE COMBUSTION CHAMBER WITH PERFECTED AIR FEED MEANS Russian patent published in 2014 - IPC F23R3/10 

FIELD: engines and pumps.

SUBSTANCE: combustion chamber (10) comprises bottom (22) at chamber (10) inlet side, chamber bottom circular cowl (78) arranged at chamber bottom (22) inlet. Besides it comprises several fuel and air injector systems (32) arranged in circle around combustion chamber (10) axis (34) at chamber bottom (22). Combustion chamber comprises air manifold (100) communicated with every injector system (32). Said manifold comprises at least two webs (96, 98) arranged at chamber bottom (22) to extend towards inlet on both side of injector system (32) to hinder peripheral air from around combustion chamber (10) axis (34). Said webs (96, 98) are connected, in fact, tightly with circular cowl (78) on both sides of appropriate opening. Said opening is made in said circular cowl (78) to make the inlet of said air manifold (100). Air inlet (88) is open radially outward relative to injector system axis (44). Said webs (96, 98) are arranged radially, each making the part of two serial air manifolds (100).

EFFECT: decreased airflow head losses, more uniform air feed of combustion chamber injection systems.
