Abstract : A diffuser and baffle device prevents sea water intrusion or ingestion into a marine gas turbine engine exhaust system without significantly increasing exhaust back pressure. Inboard and outboard rows of vertical turning vanes are separated by a gap and effect successive bends of the exhaust flow in opposite directions while affording an increase in cross-sectional area. The outboard vanes are slotted at their inboard edge portions, and the inboard vanes are provided with hook-shaped projections defining grooves, whereby water driven into the device is arrested and drained overboard.
