Lubrication system with multiple lubrication circuits

A system for a turbine engine, comprising:

• a first bearing and a second bearing;
• a first rotating assembly including a first component rotatably supported by the first bearing;
• a second rotating assembly including a second component rotatably supported by the second bearing;
• a first lubrication circuit comprising a first pump and the first bearing, the first pump driven by the first rotating assembly and configured to pump lubricant to the first bearing during nominal operation of the turbine engine;
• and
• a second lubrication circuit comprising a second pump and the second bearing, the second pump configured to pump lubricant to the second bearing during the nominal operation of the turbine engine.

A system for a turbine engine, comprising:

• a first rotating assembly including a fan rotor, a first compressor rotor and a first turbine rotor mechanically coupled to the fan rotor and the first compressor rotor, wherein a first component of the first rotating assembly is rotatably supported by a first bearing;
• a second rotating assembly including a second compressor rotor and a second turbine rotor mechanically coupled to the second compressor rotor, wherein a second component of the second rotating assembly is rotatably supported by a second bearing;
• a first lubrication circuit comprising a first pump and the first bearing, the first pump driven by the first rotating assembly and configured to pump lubricant to the first bearing;
• and
• a second lubrication circuit comprising a second pump and the second bearing, the second pump configured to pump lubricant to the second bearing, wherein the second lubrication circuit is configured discrete from the first lubrication circuit and the first bearing during nominal operation of the turbine engine.
