Aerodynamic injection system for aircraft turbine engine, having improved air/fuel mixing

To improve air/fuel mixing at low speed, the invention concerns an aerodynamic injection system (30) for a combustion chamber (8) of an aircraft turbine engine, the system comprising a central body (70) comprising a first air circulation space (72) and a swirler (74) allowing air to penetrate into t...

description	To improve air/fuel mixing at low speed, the invention concerns an aerodynamic injection system (30) for a combustion chamber (8) of an aircraft turbine engine, the system comprising a central body (70) comprising a first air circulation space (72) and a swirler (74) allowing air to penetrate into the first air circulation space (72), the hollow body (70) also comprising a fuel circuit (92, 93, 82) arranged at least partially around the first space (72), the circuit comprising a second annular space (82) for a fuel film to circulate and fuel supply structures (92, 93) communicating with the second space (82), the spaces (72, 82) opening into a third air and fuel mixing space (86). According to the invention, the system comprises fuel injection openings (90) that bring the fuel circuit into communication with the first space (72).
