1. A thermal management system for a gas turbine engine including a compressor section, a combustion section, and a turbine section in serial flow order and at least partially defining a working gas flow path, the thermal management system comprising:
an oil tank comprising a solid-solid phase change material, a solid-liquid phase change material, or both the solid-solid phase change material and the solid-liquid phase change material, wherein the oil tank comprises at least one wall formed of the solid-solid phase change material;
a pump in fluid communication with the oil tank, the pump configured to generate a flow of oil from the oil tank;
at least one heat exchanger positioned downstream of the oil tank; and
one or more thermal loads positioned downstream of the at least one heat exchanger.
