Space Shuttle Blueprint

This section of paper was a piece of a blueprint used to manufacture a critical component of the space shuttle columbia.
We acquired several sheets of this set of prints from the estate of an engineer on the project. These are not modern reproductions. They were produced in the 1970s for use in the space shuttle orbiter development.
History:
In 1972, nasa hired ltv aerospace to develop the shuttle entry air data system (seads) a method for measuring air pressure distribution around the spacecraft’s nose during reentry.
Due to the extreme heat of reentry, which could reach temperatures as high as 2,700° f (1,480° c), this assembly and the leading edges of the wings were protected by black tiles made of reinforced carbon-carbon material (rcc).
