To address this thermal challenge, DARPA recently announced its Materials Architectures and Characterization for Hypersonics (MACH) program. The MACH program seeks to develop and demonstrate new design and material solutions for sharp, shape-stable, cooled leading edges for hypersonic vehicles. A Proposers Day describing the program will take place January 22, 2019 in Arlington, Virginia.
“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 Sciences Office. “The key is developing scalable materials architectures that enable mass transport to spread and reject heat. In recent years we’ve seen advances in thermal engineering and manufacturing that could enable the design and fabrication of very complex architectures not possible in the past. If successful, we could see a breakthrough in mitigating aerothermal effects at the leading edge that would enhance hypersonic performance.”
The MACH program will comprise two technical areas. The first area aims to develop and mature fully integrated passive thermal management system to cool leading edges based on scalable net-shape manufacturing and advanced thermal design. The second technical area will focus on next-generation hypersonic materials research, applying modern high-fidelity computation capabilities to develop new passive and active thermal management concepts, coatings and materials for future cooled hypersonic leading edge applications. Both technical areas will be described in a Broad Agency Announcement solicitation expected in mid-January 2019 on DARPA’s FedBizOpps page here: http://go.usa.gov/Dom.
The MACH program seeks expertise in thermal engineering and design, advanced computational materials development, architected materials design, fabrication and testing (including net shape fabrication of high temperature metals, ceramics and their composites), hypersonic leading-edge design and performance, and advanced thermal protection systems.
