A disassemblable exhaust muffler and cabin air heater suitable for use on aircraft engines or the like comprising a plurality of assemblable modules which can be readily disassembled to facilitate periodic inspection and repair of the muffler assembly in accordance with prescribed maintenance and inspection schedules. The muffler assembly includes a perforated exhaust gas conduit having a gas flow obstruction at a position intermediate of the inlet and outlet ends thereof and around which an inner shell is removably disposed defining an inner chamber for sound attenuation which in turn is encircled by a removable outer shell defining an outer chamber through which cabin air is adapted to be passed in heat exchange relationship with respect to the periphery of the inner shell. The outer shell and inner shell are readily disassemblable to expose internal areas to inspection for the presence of any structural defects and for effecting any repair thereof.

An aircraft muffler and cabin air heater assembly or the like comprising an elongated gas flow conduit having an inlet end and an outlet end and formed with an annular connector around one end portion thereof, an elongated inner shell disposed in encircling spaced relationship around a substantial portion oF said conduit and defining therebetween an annular inner chamber, said inner shell having one end thereof necked down to slidably overlie and engage the other end portion of said conduit and having the opposite end thereof removably coupled to said annular connector at said one end portion forming a substantially gas-tight connection, said conduit formed with a gas flow obstruction at a position intermediate the ends thereof and provided with perforations through the walls thereof in a region upstream and downstream of said obstruction for providing communication between the interior of said conduit and said inner chamber, and an outer shell removably mounted in encircling spaced relationship around said inner shell including axially spaced end walls defining in combination an outer chamber which is axially spaced from said connection, said outer shell formed with inlet means and outlet means for passing air in heat exchange relationship through said outer chamber.
