    摘要： The invention relates to an element (201) for injecting a mixture of at least one first propellant (E1) and one second propellant (E2) into a combustion chamber. The injection element (201) includes a first tubular wall (202) defining a first channel (206) for injecting the first propellant (E1), and a second wall (204) surrounding the first wall (202) and defining, between the first and second walls, a second channel (207) for injecting the second propellant (E2). The first wall (202) includes a first electrode for igniting the mixture by electrical discharge.
