INJECTION SYSTEM WITH CONCENTRIC SLOTS AND ASSOCIATED INJECTION ELEMENTS

摘要

Parallel flow injector having a circular body (10), based on an axis of symmetry (11), with which is coaxially associated at least one annular injection element (12, 14) comprising a central annular injection slot (212) surrounded by two other annular injection slots (218, 219). The central annular slot is supplied with a second propellant entering the top of the injection element at the central slot and the other annular slots are supplied with a first propellant which enters at the base of the injection element, on either side of the central slot, and passes through an annular homogenizing cavity (203) from which it flows towards the annular slots surrounding the central injection slot. The invention also concerns injection elements which can be associated with the injector.
