Abstract (en)
[origin: EP1640661A2] The aerodynamic injection system (2) has an air feed channel (6) to supply air to a tubular structure (4). A fuel passage (8) is connected to a fuel feed channel (10). A gas injection channel (12) injects gas into fuel feed channel at a pressure which is greater than pressure of air supplied to tubular structure and greater than or equal to pressure of fuel flowing in fuel feed channel, to create effervescence in fuel. Independent claims are also included for the following: (1) turbomachine combustion chamber; and (2) turbomachine.
