a supply housing for containing a fire extinguishing agent;
a line for routing the fire extinguishing agent from the supply housing; and
a nozzle structure operatively coupled to the line, the nozzle structure having an opening for expelling the fire extinguishing agent, wherein the nozzle structure is located within an annular space defined by the engine core and the nacelle,
the opening is recessed with respect to the face of the nozzle structure, the opening defined by a face of the nozzle structure, and the opening through which fluid passes is end-to-end continuous and comprises:
a first linear segment and a second linear segment oriented perpendicularly to the first linear segment so that the opening through which fluid passes defines an L-shape with first and second straight legs that extend from a vertex; and
an arc shaped segment extending continuously from the second linear segment so that the opening through which fluid passes further defines an arc shape leg that extends beyond the second straight leg.
