Abstract
A turning vane arrangement (30) for an IR suppressor having a duct (32) adapted for receiving a primary flow PF of engine exhaust. The turning vane arrangement (30) is operative to direct a pressurized secondary flow PSF of low temperature gaseous fluid into the primary flow of engine exhaust for reducing the IR energy thereof. The turning vane arrangement (30) includes at least one turning vane (50) situated in the duct (32) and is characterized by a trailing edge (50TE) that defines an exhaust nozzle (52). The exhaust nozzle (52) is adapted for being disposed in fluid communication with a flow source (54) which produces the pressurized secondary flow PSF. The exhaust nozzle may include a plurality of adjoined lobes (60R, 60A or 60P) for rapidly and thoroughly admixing the primary and pressured secondary flows PF, PSF.
