DARPA-funded team proposes "sweating" hypersonic missiles to beat heat

In a significant development to overcome the challenges posed by hypersonic missiles, the Defense Advanced Research Projects Agency (DARPA) has turned to an unusual but effective solution: making the missile "sweat." Researchers at the RTX Technology Research Center, under the guidance of John Sharon, are developing a cooling mechanism that leverages transpiration cooling channels in the tip of
