Abstract
A lubrication system for an aerial vehicle, the lubrication system including: a lubrication oil (LO) tank configured to operate at a first internal pressure; and an intake chamber (IC) configured to operate at a second internal pressure greater than the first internal pressure, the IC including an ingress port configured to receive LO from a sump of an equipment of the aerial vehicle; an overflow port in fluid communication with the LO tank; and a supply port in fluid communication with the sump and configured to supply LO to the sump.
Claims13
A lubrication system for an aerial vehicle, the lubrication system comprising:
- a lubrication oil (LO) tank configured to operate at a first internal pressure;
- and
- an intake chamber (IC) configured to operate at a second internal pressure greater than the first internal pressure, the IC comprising:
- an ingress port configured to receive LO from a sump of an equipment of the aerial vehicle, wherein the sump comprises a first egress port and a second egress port, wherein the first and second egress ports are disposed on generally opposite sides of the sump, and wherein the ingress port of the IC is in fluid communication with both the first and second egress ports of the sump;
- an overflow port in fluid communication with the LO tank;
- and
- a supply port in fluid communication with the sump and configured to supply LO to the sump;
- a makeup fluid circuit having a first makeup fluid passageway and a second makeup fluid passageway in fluid communication with the LO tank at generally opposite sides of the LO tank;
- and
- an air-oil separator in fluid communication with the first and second fluid passageways and the first and second makeup fluid passageways, and wherein the oil-air separator is configured to provide the LO to the IC and vent air to an external environment.
An aerial vehicle comprising:
- a lubrication system, the lubrication system comprising:
- a lubrication oil (LO) tank configured to operate at a first internal pressure;
- and
- an intake chamber (IC) configured to operate at a second internal pressure greater than the first internal pressure, the IC comprising:
- an ingress port configured to receive LO from a sump of an equipment of the aerial vehicle, wherein the sump comprises a first egress port and a second egress port, wherein the first and second egress ports are disposed on generally opposite sides of the sump, and wherein the ingress port of the IC is in fluid communication with both the first and second egress ports of the sump;
- an overflow port in fluid communication with the LO tank;
- and
- a supply port in fluid communication with the sump and configured to supply LO to the sump;
- a makeup fluid circuit having a first makeup fluid passageway and a second makeup fluid passageway in fluid communication with the LO tank at generally opposite sides of the LO tank;
- and
- an air-oil separator in fluid communication with the first and second fluid passageways and the first and second makeup fluid passageways, and wherein the oil-air separator is configured to provide the LO to the IC and vent air to an external environment.
