Ann, while the application of composites for the booster is new stuff, their use in the spacecraft itself is old hat. I worked at one spacecraft plant where we made our own composites from raw materials. One of our direct competitors, with whom we were merged later on, got their composites from a company whose main business was railcars. It was an interesting revelation when we found out.
I actually worked on the testing of the UARS satelite structure. It was the first large composite structure. If you recall, UARS recently fell back to earth. It was one of the largest satellites to do so. It was the size of a school bus and filled the Shuttle cargo bay. In testing we found some interesting things out about how the composites reacted structurally. Now, this was in the 1980s. It would have been nice to have some of the more robust CAE tools available today.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
