Abstract
Briefly, the disclosure relates to apparatuses and methods to form a gearbox enclosure comprising an external liner, an internal liner, and a variable porosity region disposed between the external liner and the internal liner. The variable porosity region may be configured to accommodate flow of the lubricant, thereby providing a capability to cool, for example, a lubricating fluid at an elevated temperature.
Claims10
A gearbox enclosure, comprising:
- an external liner;
- an internal liner;
- a gearset surrounded by the gearbox enclosure,
- a porosity region disposed between the external liner and the internal liner;
- and
- a lubricant conduit disposed within the porosity region, configured in a reciprocating path from a base portion of the gearbox enclosure to a portion of the gearbox enclosure that opposes the base portion,
- wherein the lubricant conduit is configured for a lubricant to flow therethrough, and
- wherein the external liner, internal liner, and the porosity region are configured to provide load-bearing capability.

A gearbox enclosure for a rotor system of a rotary-wing aircraft, comprising:
- one or more lubricant input ports;
- one or more lubricant output ports;
- a gearset surrounded by the gearbox enclosure,
- a porosity region disposed between the one or more lubricant input ports and the one or more lubricant output ports and disposed between an internal liner and an external liner of the gearbox enclosure and
- a lubricant conduit disposed within the porosity region, configured in a reciprocating path from a base portion of the gearbox enclosure to a portion of the gearbox enclosure that opposes the base portion,
- wherein the lubricant conduit is configured to permit a lubricant to flow between the one or more lubricant input ports to the one or more lubricant output ports.
