The Pentagon's Defense Advanced Research Projects Agency (DARPA) is seeking new designs for cooling super-hot leading edges of hypersonic vehicles as they rip through the air at more than five times the speed of sound.
In a mid-December press release, DARPA explained that hypersonic weapons traveling through the atmosphere at "incredibly high speeds" create "intense friction with the surrounding air," which produces furnace-like temperatures, particularly at the leading edges or forward parts of the vehicle.
Challenge - DARPA - Materials - Architectures - Characterization
To address this thermal challenge, DARPA announced its Materials Architectures and Characterization for Hypersonics (MACH) program.
The press release describes the MACH program as an attempt to "develop and demonstrate new design and material solutions for sharp, shape-stable, cooled leading edges for hypersonic vehicles." DARPA has plans to formally release the new program on January 22, 2019, in Arlington, Virginia.
Decades - People - Edges - Vehicles - Concepts
“For decades people have studied cooling the hot leading edges of hypersonic vehicles but haven’t been able to demonstrate practical concepts in flight,” said Bill Carter, program manager in DARPA’s Defense...
