A contoured thrust reverser and lobed nozzle noise suppressor is meant for use with gas turbine engines that have conventional post-exit thrust reversers and that require only moderate levels of noise suppression. The contoured thrust reverser and lobed nozzle noise suppressor comprises a conventional tailpipe frame terminating in a lobed nozzle, and a conventional thrust reverser mechanism holding a pair of contoured blocker doors. In a deployed position, the blocker doors lie aft of the lobed nozzle, having been moved there by the thrust reverser mechanism. The blocker doors abut one another and form a fore-facing scoop, wherein any engine exhaust exiting the lobed nozzle is redirected towards the fore of the engine. In a stowed position, the blocker doors lie over the tailpipe frame and align and nestle together with the engine's cowling. Since the blocker doors partially overlap the lobed nozzle in this position, aft portions of each blocker door are contoured to correspond in shape to an exterior fore portion of the lobed nozzle of which they overlap. The lobed nozzle and contoured blocker doors provide a substantially continuous outer surface aerodynamically configured to help in mixing ambient air with engine exhaust, so as to reduce engine noise.
