Classification: CPC B  F | IPC B  F

Claim 13:
14. A powerplant for an aircraft, comprising:
a power unit rejecting heat at a nominal heat rejection rate; and
a vapor-to-air heat exchanger including:
an evaporator thermally coupled to the power unit so as to supply vapor at a nominal pressure upon the power unit rejecting heat at the nominal heat rejection rate; and
a condenser including a condenser inlet downstream of the evaporator, a condenser outlet, and at least one pneumatic vessel being inflatable and defining an cavity in fluid communication between the condenser inlet and the condenser outlet, the at least one pneumatic vessel being configurable between a collapsed vessel configuration and an inflated vessel configuration, the at least one pneumatic vessel being inflatable from the collapsed vessel configuration to the inflated vessel configuration upon the cavity being pressurized up to the nominal pressure.
