Monday materials fun: Robotic flying ‘maple seed’ vehicle with two moving parts

By / August 22, 2011

I used to imagine a lot of the bio-inspired ideas, such as flying maple seed pods (above) and artificial jellyfish arose on Thursday or Friday afternoons around happy hour time by brain-fried engineers. You know: It’s easy to imagine sensor, battery, propulsion and aeronautics wonks knocking down a few IPAs and hatching a new scheme…

University of Limoges developing composite ceramics for aeronautics applications

By Martin Grolms / August 4, 2011

ZrC-SiC materials from poly(methylvinylsilane) Credit Pizon, et al.; Advanced Engineering Materials. New advanced materials are often drivers of technologies, especially for aeronautics applications. Many materials have been developed to resist severe working conditions, which usually couple high-temperature and mechanical-stress corrosion resistance. For these applications, non-oxide ceramics are promising materials, particularly transition metal carbides, such as zirconium…

Video of the week: The Shirtsleeve Invention

By / June 22, 2011

I learned about the existence of this video after I wrote my review of Gloria Beasley Lausten’s book about the work by her husband (Bob Beasley) on the NASA’s Space Shuttle tile-based thermal protection system.

Beasley biography details quest for space shuttle’s thermal protection system

By / June 21, 2011

If mechanical systems and the weather cooperate, July 8 will bring the 135rd and final mission of the American Space Shuttle program (STS-135). Coincidentally, I recently received a charming biography of the late Robert M. Beasley, the man who led the team that developed the shuttles’ high-temperature reusable surface insulation tiles. I think for those…
