An assembly is provided for a rotorcraft. This rotorcraft assembly includes a fuselage, a tail and a rotorcraft lift system. The tail boom is connected to and projects longitudinally out from the fuselage. The rotorcraft lift system includes a rotorcraft rotor and a powerplant configured to drive rotation of the rotorcraft rotor to generate rotorcraft lift. The powerplant includes a heat engine and a powerplant flowpath. The powerplant flowpath extends through the heat engine. The outlet from the powerplant flowpath is fluidly coupled to an interior volume in the tail boom.
