New paint for stealth jets is even better at hiding them from radar and lasts longer than the coating currently used on USAF s fleet
The spray-on ceramic allows engineers to quickly apply the stealthy skin without sacrificing designs that hurt the jet s speed and performance
The skin is harder than sand when it sets and withstands harsh conditions
It is applied as a liquid and becomes hard when exposed to ambient air
The new coating can also withstand temperatures over 3,000F
A tougher skin that also has more desirable stealth characteristics will allow designers to rethink the stealth jet, researchers report.
Stealth fighters and bombers are among the most expensive aircraft in the world, and they rely on a radar-absorbent polymer skin to avoid detection. But that polymer is so fragile that these high-end aircraft have to be designed in ways that protect the skin even if that means hurting their performance in the air.
“It comes down to this: if we get the support we need to scale this up, aircraft manufacturers will be able to fundamentally redesign stealth aircraft,” says Chengying “Cheryl” Xu, whose research team at North Carolina State University developed the tougher radar-absorbent material.

NEW YORK, May 14, 2021 /PRNewswire/ Researchers have discovered new ways in which the COVID-19 virus causes human immune cells to overreact, a deadly part of the disease.
Led by researchers from NYU Grossman School of Medicine and the Perlmutter Cancer Center at NYU Langone Health, the new study found that SARS-CoV-2, the pandemic virus, interacts with specific proteins on immune cells, causing these cells to release abnormally high levels of immune signaling proteins called cytokines (a cytokine storm ). These cytokines, in turn, cause fluid buildup in the lungs and makes it hard to breathe.
