Cool Edge: DARPA Seeks Tech to Keep Hypersonic Vehicles From Overheating
The US military’s Defense Advanced Research Projects Agency (DARPA) is looking for engineers to develop new, innovative materials to construct hypersonic vehicles that don’t heat up while traveling more than five times the speed of sound.
In a press release earlier this month, DARPA noted that hypersonic vehicles traveling through the atmosphere at "incredibly high speeds" create "intense friction with the surrounding air," which produces heat, particularly at the leading edges or forward parts of the vehicles.
"Developing structures that can withstand furnace-like temperatures at such high speeds is a technical challenge, especially for leading edges that bear the brunt of the heat," the release notes.
