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 containing fuel and air channels, and a fuel collector connected to the plate, collector cavity being connected to fuel channels with injector modules. Over three concentric rows of injector modules are installed, the modules are installed with register ledge inserted into blind hole made in the plate. The plate is designed convex towards air flow.
EFFECT: invention is meant for improvement of fuel combustion completion, reduction of harmful emissions at all the modes and provision of uniform temperature field at combustion chamber outlet in a circumferential direction at all the modes.
