摘要： The invention provides an injection system for injecting an air/fuel mixture into a combustion chamber of a gas turbine engine, the injection system having a longitudinal axis and comprising fuel injection means, interposed between first and second air injection means, the fuel injection means being disposed in an annular internal cavity of a Venturi, the fuel injection means comprising at least a first fuel admission circuit provided with at least one fuel injection orifice, and a plurality of second fuel admission circuits independent from the first fuel admission circuit(s), each being provided with at least one fuel injection orifice so as to define a plurality of independent modes of injecting the air/fuel mixture depending on determined operating speeds of the engine, the fuel injection orifice of the first fuel admission circuit being formed in the upstream wall of the Venturi so as to inject fuel towards the combustion chamber in a general direction that is substantially perpendicular to a flow of air coming from the first air injection means, and the fuel injection orifices of the second fuel admission circuits being formed in the downstream wall of the Venturi so as to inject fuel towards the combustion chamber in a general direction that is substantially perpendicular to a flow of air coming from the second air injection means.
摘要翻译：本发明提供了一种用于将空气/燃料混合物喷射到燃气涡轮发动机的燃烧室中的喷射系统，所述喷射系统具有纵向轴线并且包括介于第一和第二空气喷射装置之间的燃料喷射装置，燃料喷射装置设置在文氏管的环形内腔中，燃料喷射装置至少包括设有至少一个燃料喷射孔的第一燃料允许电路和独立于第一燃料允许电路的多个第二燃料允许电路，每个设置有至少一个燃料喷射孔，以便根据确定的发动机的运行速度来限定喷射空气/燃料混合物的多个独立模式，第一燃料允许电路的燃料喷射孔形成在上游文丘里管壁，以便在基本上延伸的大致方向上向燃烧室喷射燃料相当于来自第一空气喷射装置的空气流，并且第二燃料允许回路的燃料喷射孔形成在文丘里管的下游壁中，以便在大致方向上向燃烧室喷射燃料垂直于来自第二空气喷射装置的空气流。
