1. A thrust reverser of a nacelle of a turbojet engine of an aircraft extending about a longitudinal axis, comprising:
a fixed structure and at least one door rotatable between a closed position in which said door provides aerodynamic continuity with the fixed structure for the circulation of an air flow and an open position in which the circulating air flow is diverted to the exterior and upstream of the thrust reverser, the fixed structure comprising a downstream frame comprising an upstream end spaced axially from a downstream end edge of the door by an axial clearance parallel to the longitudinal axis;
at least one fluid diverter system for diverting fluids to the exterior of the thrust reverser associated with the door, wherein the fluid diverter system comprises at least one deflector group comprising at least one projection fixed onto one of the door or the fixed structure and extending locally from one of downstream end edge of the door or the upstream end of the downstream frame in the axial clearance and towards one of the upstream end of the downstream frame or the downstream end edge of the door, while leaving an axial gap between a free end of said projection and one of the upstream end of the downstream frame of the fixed structure or the downstream end edge of the door, and wherein the at least one projection includes at least one first projection fixed to the downstream end edge of the door and extending locally into the axial clearance and towards the upstream end of the downstream frame of the fixed structure and at least one second projection fixed to the upstream end of the downstream frame of the fixed structure and extending locally into the axial clearance and towards the downstream end edge of the door.
