FIELD: engines and pumps.
SUBSTANCE: injector unit of gas-turbine engine combustion chamber includes a plate of annular shape with injector modules installed on it in several rows, and a primary fuel collector connected to the plate, collector cavity being connected to fuel channels with injector modules. Injector modules are installed with register ledges inserted into the blind holes made in the plate and provided with mixing chambers of frustum-of-a-cone shape. All the injector modules have central fuel channel. Tangential air swirlers are made between the housing and the central body in the form of inclined blades. The central fuel channel is made blind with inserted tangential holes. Injector modules in rows are installed on the plate in staggered order.
EFFECT: improving fuel combustion completion at all the modes, reducing harmful emissions and providing uniform temperature field at combustion chamber outlet.
