FLOW VORTEX SPOILER

摘要

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.

1. A flow vortex spoiler for equalizing pressure between
a first location and a second location, comprising: an oil sump wherein pressurization air flow moves about said oil sump through at least one sump pressurization cavity, said cavity having an inlet; a circumferential plate disposed at said inlet to said sump pressurization cavity; said circumferential plate having a plurality of spaced apart apertures; said pressurization air flow having a radial component and a tangential component; said circumferential plate and said plurality of spaced apart apertures impinging said pressurization air and substantially reducing said tangential component of said pressurization air flow, wherein said vortex spoiler inhibits excessive pressure change within said pressurization cavity and inhibits oil leakage at forward and aft sump seals adjacent to said oil sump at said first location and said second location.
