Claim 0:
1. An exhaust device for a compressor bypass bleed system of a ducted fan engine, the exhaust device comprising: a housing having an inlet end and an outlet end, and defining a centerline axis from the inlet end to the outlet end; an inner flow conditioner arranged at the inlet end, the inner flow conditioner including a plurality of openings for conducting a flow of compressed air therethrough into the housing; and an exit screen arranged at the outlet end of the housing, the exit screen including a plurality of exit openings therethrough arranged at an acute angle with respect to the centerline axis for providing a directional flow of compressed air from the housing therethrough, wherein the exit screen defines, in a plan view of an outer surface of the exit screen, a longitudinal centerline axis extending in a same direction as a flow direction of a bypass airflow, and a lateral axis extending orthogonal to the longitudinal centerline axis, the plurality of exit openings being arranged in a plurality of rows of exit openings, including a first row of exit openings arranged on a first side of the longitudinal centerline axis, and a second row of exit openings arranged on a second side of the longitudinal centerline axis opposite the first side, the first row of exit openings extending at a first non-zero angle with respect to the longitudinal centerline axis and the lateral axis, and the second row of exit openings extending at a second non-zero angle with respect to the longitudinal centerline axis and the lateral axis.
