Abstract
An assembly is provided for an aircraft powerplant. This assembly includes a first powerplant component, a second powerplant component, a third powerplant component and a fluid system. The fluid system includes a first fluid circuit, a second fluid circuit, a third fluid circuit and a heat exchanger. The first fluid circuit extends through the heat exchanger and is configured to service the first powerplant component. The second fluid circuit extends through the heat exchanger and is configured to service the second powerplant component. The third fluid circuit extends through the heat exchanger and is configured to service the third powerplant component. The heat exchanger is configured as or otherwise includes a radiator.
