FIELD: engines and pumps.
SUBSTANCE: fuel feed unit to the afterburner of the bypass turbojet engine contains a fuel manifolds with the fuel feed fittings. The fuel manifolds are formed all-in-one with the housing, which by means of fixing elements is connected to the upper diffuser cowl and with the upper ring flame stabiliser fastener. At that the mentioned housing in the cross-section plane has a rectangular shape, and the fuel manifolds are made in the form of a ring.
EFFECT: reduction of the full pressure loss in the afterburner flow section, thrust augmentation and reduction of coke formation in the fuel manifolds.
