Radiative cooling is a cooling method employed in certain rocket engines, like SpaceX’s vacuum Merlin and Rocket Lab’s vacuum Rutherford engines. As the name suggests, this method gets rid of heat through radiation, a form of heat transfer that does not require matter. Through using nozzle extensions made of alloys like niobium, radiative cooling dissipates the heat into space. While the nozzle extensions can handle high heat, they are somewhat fragile, making them impractical to use as a primary rocket engine cooling method. Read full article here
