Thermal tile processing system

The process of safety-guided design and the use of STPA to support it is illustrated here with the design of an experimental Space Shuttle robotic Thermal Tile Processing System (TIPS) based on a design created for a research project at CMU [57]. 

The high-level system hazards that might be derived from the accidents defined for the NASA thermal tile processing robot in section 7.1 might be ... 

Yasinskaya et al. (2011) studied flexural strength and thermal conductivity of poly ester/acrylic and polyester/wool insulating tiles as a function of polyester proportion in the mixture and volume density. The analysis of regression equations enabled the optimum combination of factors to be found which provides the required thermal insulation and mechanical properties of the tiles. Karthik and Murugan (2013) optimized the spinning parameters of DREF-3 system. Akyol et al. (2013) considered an industrial textile drying process.

Aerospace applications of ceramic matrix composites to date have been limited. Perhaps the most significant are the aircraft engine flaps used on a French fighter. There are two types. Both use silicon carbide matrices. One is reinforced with carbon fibers, and the other with a multifllament silicon carbide fiber. Another application is a missile diverter thruster made of carbon fiber-reinforced silicon carbide. Again, the process used to make this part is CVI. The Space Shuttle Orbiter thermal protection system (TPS) makes extensive use of tiles composed of a three-dimensional network of discontinuous oxide fibers with silicate surface layers. While there is no continuous matrix for most of the tile, the surface region is a form of CMC. In a sense, this can be considered to be a type of functionally graded material.
