Abstract:

A flow vortex spoiler including an oil sump wherein pressurization air flow moves about the oil sump through a sump pressurization cavity, the cavity having an inlet, a circumferential plate disposed across a portion of the pressurization cavity near the inlet. The circumferential plate is disposed at said inlet to said sump pressurization cavity. The circumferential plate has a plurality of closely spaced apertures. The pressurization air has a radial component and a tangential component wherein the circumferential plate and the plurality of closely spaced apertures substantially reduce the tangential component of the pressurization air and further wherein the vortex spoiler inhibits excessive pressure change within the pressurization cavity and inhibits oil leakage at seals adjacent to the oil sump.
