Methods and apparatuses for passive jet blast deflection or the like. Use of the passive jet blast deflector permits the efficient dispersal of a fast moving local heat source into the environment through passive means while providing a high strength structure. The jet blast deflector system may include a first plate, a second plate, and a cellular core disposed between them adapted to allow cooling ambient air to flow through the cellular core, wherein the first plate, second plate, and core are all seamlessly coupled heat pipes that form a single vapor core to facilitate the spreading and even storing of thermal energy. An ejector plate may be attached to the top of the second plate to create a low pressure zone as the heat source passes over it, thereby pulling the ambient air through the cellular core, facilitating the removal the thermal energy from the system.
