Aircraft component additively having thermally adaptive material and a thermoelectric junction
A device, having: a base having an outer boundary and a plurality of base voids, formed from a first material having a first coefficient of thermal expansion (CTE); beads that line ones of the base voids, formed from a second material having a second CTE that differs from the first CTE, wherein each of the beads has a bead void; and a thermoelectric junction around the outer boundary, or within one or more of the bead voids.
1 . A device, comprising:
a base having an outer boundary and a plurality of base voids, formed from a first material having a first coefficient of thermal expansion (CTE);
beads that respectively line each one of the base voids, formed from a second material having a second CTE that differs from the first CTE, wherein each of the beads has a bead void; and
a thermoelectric junction around the outer boundary, or within one or more of the bead voids,
wherein the device is a compressor case of a cabin air compressor; and
a section of the device defines a bypass port that is opened or closed by driving current, through the thermoelectric junction, in a first direction or a second direction.
2 . The device of claim 1 , wherein:
the thermoelectric junction is a Peltier device.
3 . The device of claim 1 , wherein:
one or more of the first material and the second material is a bistable metal, alloy or composite.
4 . The device of claim 1 , wherein:
a base outer surface is formed from the second material.
5 . A cabin air compressor comprising the device of claim 1 .
