Ultrahigh-temperature ceramics are promising materials for protecting aircraft wings from friction during hypersonic flight—but thermal shock can cause these ceramics to crack. In the cover article for the March 2020 International Journal of Ceramic Engineering & Science, researchers in China report how wing shape affects thermal shock behavior of UHTCs.

Faster than a speeding bullet: A review on fiber reinforced UHTCMCs for hypersonic aircraft and more
Ultra-high temperature ceramic matrix composites could be used on some of the hottest portions of hypersonic aircraft if their brittleness is reduced. Research on using fibers to reinforce these materials increased greatly in the past decade, and a recent review article in an ACerS journal discusses the progress and challenges in this field.

With just under 200 of 12,000 satellites launched, SpaceX’s planned Starlink constellation is already causing major complications for astronomers. Global internet coverage could theoretically be achieved with only four satellites, and a new paper proposes a way to make such a constellation economically feasible.
