Multi-boss flange

A fuel tank flange assembly, comprising:

• a flange body including a base region, a raised region, and a sloped region extending there between, wherein said raised region is positioned vertically upwardly from said base region as measured along a vertical axis of said flange body, and wherein said sloped region includes a plurality of section lines;
• a first component aperture and a second component aperture each positioned on said raised region;
• wherein said sloped region defines a plurality of convex curved regions positioned in a plane perpendicular to said vertical axis of said flange and a plurality of concave curved regions positioned in said plane perpendicular to said vertical axis,
• wherein individual ones of said plurality of convex curved regions are each positioned between individual ones of said plurality of concave curved regions such that said sloped region defines an alternating pattern of concave and convex curved regions positioned in said plane perpendicular to said vertical axis, and wherein individual ones of said plurality of section lines define a boundary between individual ones of said alternating concave and convex curved regions, and
• wherein said flange defines a line of stress extending between said first component aperture and said second component aperture, and wherein said plurality of convex curved regions each define a normal line positioned in said plane perpendicular to said vertical axis and that intersects said line of stress.

A flange, comprising:

• a flange body including a base region, a raised region, and a sloped region extending there between, wherein said raised region is positioned vertically upwardly from said base region as measured along a vertical axis of said flange body;
• and
• a first component aperture and a second component aperture each positioned on said raised region;
• wherein said sloped region includes first, second and third continuous contour lines positioned around said raised region and a plurality of section lines that each extend from said first continuous contour line, through said second continuous contour line, and to said third continuous contour line, wherein said plurality of section lines define an alternating pattern of convex curved regions and concave curved regions extending around said raised region and positioned in a plane perpendicular to said vertical axis of said flange, and wherein said first and second continuous contour lines define a concave contour section therebetween that is positioned in a plane parallel to said vertical axis of said flange body, and wherein said second and third continuous contour lines define a convex contour section therebetween that is positioned in a plane parallel to said vertical axis of said flange body, and
• wherein said flange defines a line of stress extending between said first component aperture and said second component aperture, and wherein said alternating pattern includes first, second and third convex curved regions that each define a normal line positioned in said plane perpendicular to said vertical axis and that intersects said line of stress.
