Permanent set of the Space Shuttle Thermal Protection System Reinforced Carbon–Carbon material

The objective of this paper is to provide an interpretation and understanding of the permanent set (or deformation) phenomenon observed from debris impacts on Space Shuttle Thermal Protection System (TPS) Reinforced Carbon–Carbon (RCC) panels. Deflection test results for static and dynamic loadings of RCC material will be presented. Permanent set has been observed for both the static and dynamic loading onto RCC material, even for cases where no damage was detected using conventional Non-Destructive Evaluation (NDE) techniques. Although, the RCC material is considered to be brittle, the evidence of permanent set indicates a tough-brittle material behavior with plasticity. The post-test observation of permanent set, without NDE-detectable damage, indicates an opportunity for an alternative method for assessing debris impacts.

Changes in Toyota Motors’ operations management

A key driver behind Toyota Motors’ rise to prominence has been the Toyota Production System (TPS). This pillar of the firm's competitive strength was developed over several decades. As of the late 1980s, various changes were introduced into the TPS. Some of these, such as line segmentation, the use of inter-segment buffers and high-tech automation, have been portrayed as breaks with TPS foundations. With virtually no exception published accounts on these changes stop with the situation in the mid-1990s. Based on general literature and three factory visits, this article aims to provide an update on the situation in April 2001.     

复合增塑剂增塑红苕淀粉的研究

采用双螺杆挤出机制备了红苕热塑性淀粉(TPS)和高密度聚乙烯(HDPE)/塑化淀粉共混材料.通过X射线衍射和扫描电镜分析了甘油/尿素/乙醇胺复合增塑剂的增塑效果和结晶行为,结果表明,复合增塑剂可以使淀粉塑化,能明显抑制红苕淀粉的重结晶.甘油含量的增多可以改善TPS与HDPE的相容性,同时会引起少量重结晶,但是不会影响到材料的使用性能.此外,共混材料随热塑性淀粉中甘油含量的增多,拉伸强度逐渐下降,而断裂伸长率逐渐增大.     

PRA as a management tool: organizational factors and risk-based priorities for the maintenance of the tiles of the space shuttle orbiter

A probabilistic risk assessment (PRA) model, developed for the Thermal Protection System (TPS) of the space shuttle orbiter and presented in the previous paper, is used as a management tool to identify root-cause, organizational factors of the various failure modes. The objective is to set priorities in the process of resource allocation to minimize the risk of accident caused by the failure of the TPS. Starting with the technical characteristics of the system and the inputs of the risk assessment model, the approach is to identify the human decisions and actions and the key organizational factors that influence the risk.

Among the management factors that affect the reliability of the TPS are time pressures that have occurred in the past, liability concerns and conflicts among contractors, the low status of the tile work and material technicians among maintenance personnel, the absence of priorities in tile testing, and under-recognized couplings among subsystems (such as the external tank insulation as a source of debris that may hit the tiles). It is shown here how using the PRA results to set priorities in the maintenance of the tiles can allow reduction of the overall risk, and how critical zones of debris sources can be identified on the surface of the external tank and the solid rocket booster. It was found, for instance, that detecting and fixing loose tiles in the most risk-critical areas and securing insulation by up to 80%, and securing the insulation of external systems in specified areas could reduce the TPS risk by about 75%.

People Pillars: Re‐structuring the Toyota Production System (TPS) House Based on Inadequacies Revealed During the Automotive Recall Crisis

Toyota has long been recognized as a leader in lean manufacturing and production quality through a dedicated practice of continuous process improvements and waste elimination techniques hallmarked within their Toyota Production System (TPS) and the ‘Toyota Way’ principles. Toyota's long list of successes and quality achievements has inspired companies within all industry sectors, not just automotive, to seek application of the coveted TPS into their process models in hopes of achieving the rewards that lean production promises. However, a recent series of automotive recall announcements associated with Toyota quality control have led many industry experts and students to reflect on possible inadequacies of the TPS House model. This article seeks to identify potential structural shortcomings and possible deficiencies of the TPS House in light of the root causes of recall crisis and suggest potential re‐structuring to better achieve continuous improvement.

Thermal Analysis of Thermal Protection System of Test Launch Vehicle

In this paper, a thermal analysis of the thermal protection system (TPS) of test launch vehicle (TLV) is explained. TLV is heated during the flight due to engine exhaust plume gas by thermal radiation and a TPS is needed to protect the vehicle from the heating. The thermal analysis of the TPS is conducted to predict the heat flux from plume gas and temperature of the TPS during the flight. To simplify the thermal analysis, plume gas radiation and radiative properties are assumed to be surface radiation and constants, respectively. Thermal conductivity, emissivity and absorptivity of the TPS material are measured. Proper plume conditions are determined from the preliminary analysis and then the heat flux and temperature of the TPS are calculated.
