Claim 10:
11. A gas turbine engine, the gas turbine engine comprising:
a turbomachine having a compressor section, a combustion section, and a turbine section arranged in serial flow order; and
an inducer assembly in fluid communication with the turbine section, the inducer assembly comprising:
a first ring with a first coefficient of thermal expansion;
a second ring disposed coaxially with the first ring and spaced from the first ring to define at least in part one or more passages defining a helical shape therebetween, the second ring with a second coefficient of thermal expansion that is less than the first coefficient of thermal expansion to passively modulate a size of the one or more passages during operation; and
a flow divider, wherein the flow divider is configured to create a temperature profile upstream of the first ring and the second ring.
