To reduce a noise and to cool a nozzle in a supersonic jet propelling engine, a sound absorbing member made of a porous plate (4) and a honeycomb structure (2) or a porous plate (4) and a torus core (3) is provided between a nozzle plate (5) and a liner (1), a cooling air (7) is caused to flow along an inner surface of the nozzle plate (5) and to impinge against the liner (1) through holes (10) of the porous plate (4). Furthermore, a number of holes (11) which are slanted on a rear side are formed in the liner (1) so that the cooling air (9) are injected...
A cooling and noise reducing wall assembly for an exhaust gas nozzle of a supersonic jet engine, said wall assembly comprising: a nozzle plate; a liner spaced from said nozzle plate, said liner having a first surface, a second surface exposed to hot combustion gases, and a plurality of holes extending between said first surface and said second surface; a honeycomb structure spaced from said nozzle plate and having a first side opposing said nozzle plate and a second side positioned directly on said first surface of said liner; and a porous plate attached...
