FIELD: gas turbine engines. SUBSTANCE: proposed fuel nozzle with tangential air inlet is provided with combustion chamber inlet hole to pass air and fuel into combustion chamber. Said hole has convergent surface, divergent surface and cylindrical surface between convergent and divergent surfaces. Convergent surface falls at first length along longitudinal axis of nozzle, cylindrical surface falls at second length along axis, second length being at least 5% of first length. EFFECT: increased service life. 3 cl, 3 dwg
