[Read more.]( Thomas Edison once said, “Genius is one percent inspiration and ninety-nine percent perspiration.” Today, we report on a new technology that takes that maxim to its natural conclusion. 🔥 Hypersonic flight is hot - literally. Vehicles exceeding Mach 5 face scorching temperatures that are high enough to melt most metals. Now researchers have found a novel way to make them “sweat” to stay cool. Mimicking the human body's heat-dumping sweat glands, the system pumps liquid coolant to the surface where it evaporates, taking thermal energy with it. Tested at scale, this ingenious bio-inspired innovation could usher in an era of ultra-fast aircraft.

To tackle this, Raytheon Technologies researchers developed a “sweating” cooling system inspired by human sweat glands. Tiny embedded channels deliver liquid coolant to the vehicle's surface, where it evaporates and draws away heat. This maintains the vehicle's shape and performance at high speeds. In tests, a credit card-sized prototype with the channels survived exposure to intense simulated hypersonic conditions. The success proves the concept's feasibility. Now the team aims to scale up the micro-channels for full vehicle integration. Find out how this innovative bio-inspired approach could protect the ultra-fast aircraft of the future.
