Abstract: A strut may include an outer tube including an outer tube first end, an outer tube second end, and a longitudinal axis extending from the outer tube first end to the outer tube second end. The outer tube may define an interior. The strut also may include an additively manufactured inner tube at least partially within the interior of the outer tube of the strut. The additively manufactured inner tube defines an additively manufactured inner tube first end and an additively manufactured inner tube second end. The additively manufactured inner tube first end is integrally joined to the outer tube proximate to the outer tube first end.

Abstract: A bearing lubrication system includes a bearing assembly comprising a duplex bearing including an outer ring, an inner ring positioned radially inward from the outer ring, and two sets of circumferentially distributed rolling elements between the inner and outer rings. The bearing assembly further includes a housing radially surrounding the duplex bearing and including a lubricant flow passage in fluid communication with a source of lubricant. A flow orifice is located downstream of the lubricant flow passage for jetting the lubricant into the duplex bearing. The flow orifice has an axial location between the two sets of rolling elements.
