Gas turbine engine exhaust mixer with aerodynamic struts

摘要

An exhaust mixer (32) for a gas turbine engine has a plurality of circumferentially distributed alternating inner and outer lobes (42,44), and a plurality of aerodynamic struts (50) positioned and oriented between adjacent inner lobes (42) in the core flow passage. The struts (50) are configured for diverting a portion of the core flow radially outwardly in troughs formed by the outer lobes (44) on the core flow side of the mixer (32).
