ABSTRACT:
An improved fire-safe waste disposal system uniquely suitable for use in the aft bulk cargo hold (22) of a large capacity passenger aircraft which is compatible with, and can be readily interfaced with, FAA approved waste disposal chutes (39) extending through the passenger deck (25) from the aft galley into the bulk cargo hold (22) and comprising a standardized aircraft cargo container base (40), a floor (45) mounted on the base (40) and parallel therewith, a first pair of vertically extending walls (46, 49) secured to the floor (45) with one of the walls (49) being normal to the floor (45), the other of the walls (46) defining an included obtuse angle with the floor (45) and with the wall (49) having a greater height than the wall (46), and with a second pair of walls (50) rigidly secured to the first pair of walls (46, 49) and to the floor (45) in airtight fire-safe relation, a top (44) secured to the walls (46, 49, 50) in airtight fire-safe relation with the top (44) being normal to the wall (46) and defining an acute angle with respect to the wall (49), and an access opening (55) formed in the top (44) for mutual engagement with the waste chute (39). The fire-safe waste disposal container (38) includes a lip formed on the standard LD2 type base (40) mutually engageable with floor mounted tracks (61, 62) for securely clamping the container (38) to the floor (29) of the bulk cargo hold (22).
