Diffusor for an annular combustor, as well as combustor and turboprop with such a diffusor

摘要

The diffuser has a separator (36) formed of a thin sheet for distributing an air flow (38) coming from a compressor into two annular internal and external jets (40, 42). The separator is connected to internal and external orbit walls (32, 34) by structural arms (44) which extend radially between the separator and the walls. The jets delimited by the separator have diffuser angles ranging from 12 to 13 degrees.
