Abstract:
How to exploit the precipitated internal and external knowledge to build dynamic capability in the era of big data remains a big challenge for innovation and business sustainability. This paper documents a novel perspective to address this challenge by exploring the double screen innovation knowledge management practice in Commercial Aircraft Corporation of China Ltd. (COMAC). Drawing from the literature on knowledge management and knowledge-based view, this paper elaborates how the new type of knowledge management practice represented by the case of Double Screen Innovation (DSI) in COMAC could help enterprise build sustainable core competence, which provides new perspective for multi-level knowledge management towards business sustainability. DSI, as a novel way of knowledge management, optimizes the micro-level knowledge co-creation and sharing and macro-level organizational learning mechanisms to accelerate the knowledge accumulation and dissemination within the organization. The process of knowledge creation, transformation, and application helps to integrate and transform big data into useful business information, thus provides an endless driving force conducive to the establishment and promotion of the core competencies of enterprises.

Abstract:
To reasonably define the design service life of Chinese double aisles wide-body commercial aircraft, the exact market region and design condition are researched. The base market of Chinese double aisles wide-body commercial aircraft is China, Asia, Europe and the Pacific. In these zones, customers should be analyzed carefully, and the customers who are not available but play an important role in these zones should be picked off decisively. Besides, the flight length definition is also studied, which affects the design service life of aircraft obviously in small market region. After research, the results could reduce engineering difficulties, and also increase airlines adaptability and competitiveness in the specific market zone.

Abstract:
Cabin air quality and thermal conditions have a direct impact on passenger and flight crew’s health and comfort. In this study, in-cabin thermal environment and particulate matter (PM) exposures were investigated in four China domestic flights. The mean and standard deviation of the in-cabin carbon dioxide (CO2) concentrations in two tested flights are 1440 ± 111 ppm. The measured maximum in-cabin carbon monoxide (CO) concentration is 1.2 ppm, which is under the US Occupational Safety and Health Administration (OSHA) permissible exposure limit of 10 ppm. The tested relative humidity ranges from 13.8% to 67.0% with an average of 31.7%. The cabin pressure change rates at the end of the climbing stages and the beginning of the descending stages are close to 10 hPa·min−1, which might induce the uncomfortable feeling of passengers and crew members. PM mass concentrations were measured on four flights. The results show that PM concentrations decreased after the aircraft cabin door closed and were affected by severe turbulences. The highest in-cabin PM concentrations were observed in the oldest aircraft with an age of 13.2 years, and the waiting phase in this aircraft generated the highest exposures.

Abstract:
The conceptual design optimization of wide-body commercial aircraft is very challenging today. This paper deals with the conceptual design optimization problem of a next-cycle wide-body commercial aircraft, which has many similarities to the one being co-developed by China and Russia. The most difficult weaknesses are that the design requirements cannot be traded off during the conceptual design optimization process. To overcome this issue, a competitiveness model is built up for the wide-body commercial aircraft. The analytic hierarchy process is applied to formulate the competitiveness model, which is a multi-level evaluation model. The competiveness model includes three levels, i.e. target level, criteria level, and attributes level. The target level has an output, i.e. the competitiveness of the investigated aircraft, which serves as the single objective function in the conceptual design optimization problem. The criteria level includes four elements of economics, comfort, environmental impact, and adaptability. In addition, each criterion is further divided into more attributes, which are parameters obtained from the commercial aircraft conceptual design. By using the competitiveness model, the conceptual design optimization problem is converted into an unconstrained one that can be solved easily. Two optimizations with different judgment matrices for criteria level were performed. Compared with the baseline design candidate, the overall competitiveness of the optimal design for the optimization case 1 and case 2 increased by 9.28% and 11.51%, respectively, which benefits the designers and decision-makers.

Abstract:
This paper presents the electromagnetic flux analysis of dual stator hybrid excitation switched flux machines (DS HESFM) using segmental rotor for the directly driven electromechanical actuator aimed to use in aerospace applications. The advantage of designing a machine with directly driven system is to eliminate the intermediate gear box system with having minor component count and reduced jamming possibility. The proposed design of DS hybrid excitation with high torque density is investigated in this paper as a potential solution for aircraft applications. The key intentions of the design are high level of actuator integration to reduce the overall weight and volume and fault tolerance ability. The proposed design of DS HESFSM has simple structure, which consist of only six field excitation coils (FECs) housed in outer stator along with six armature coils (ACs) whereas, six permanent magnets (PMs) are positioned in the inner stator. Moreover, DS HESFM structure is analyzed at open circuit and short circuit conditions conditions by means of “commercial 2D FEA package, JMAG-designer ver. 14.0,” released by JSOL Corporation.

Abstract:
In a recent article in this journal, William C. Kirby (1995) chronicled the development of China's Company Law, which was crafted in 1904 to promote industrial development by codifying a commercial code. Among other objectives, the Company Law was aimed at providing institutional support for the emergence of modern legal corporations. Indeed, it was a widespread belief among the Qing reformers of the period that “Modern industrial capitalism … demanded Western corporate structures to do business’ (Kirby 1995, 43). Kirby argued that after numerous revisions it has become clear that the Company Law has failed to promote the emergence of privately owned, publicly traded corporations. Given China's rich commercial tradition, its dramatic post-1978 reforms, and its rapid economic growth over the last two decades, Kirby's finding raises a most puzzling question for China scholars: Why is there not a single privately owned, publicly traded corporation (PPC) in mainland China?

Page 88 blank. Cataloged from PDF version of thesis.
Includes bibliographical references (p. 82-87).
Using an industry analysis framework, this thesis analyzes whether the recently established Commercial Aircraft Corporation of China (Comac) is likely to break the Boeing-Airbus duopoly in the industry of large commercial airplanes. The selected framework for this thesis is comprised by the following two principles: 1) "The nature and degree of competition in an industry hinge on five forces, one of these being the Threat of New Entrants, which depends on the height of Entry Barriers." (Porter 1979, 1) 2) "In order to cope with the competitive forces in an industry, there are three potentially successful generic strategic approaches to outperforming other firms in the industry: overall cost leadership, differentiation, and focus." (Porter 1980, 35) The results from the barriers of entry analysis suggest that Comac enjoys full unconditional support from the Chinese government as the development of an aerospace industry is deemed as national interest. However, the firm faces a high barrier of entry derived from the advantages the incumbent companies have in terms of their learning and experience curves, which allow them to effectively conduct research and development and innovate. In the long run, as the companies seek sustained competitive advantage (Porter 1984, 34), I find that Comac will mainly rely on generic strategy 'cost', while the incumbents counteract by adopting mainly generic strategy 'differentiation' and 'focus'. This thesis claims the chances of success for Comac largely depend not only on finding the right strategy for a proper balance between 'cost' and 'differentiation', but mainly on the Chinese government being able to maintain protectionist policies in place. In other words, the Chinese government must continue to decide for the domestic airlines what airplanes they should buy. This conclusion is reached by analyzing the history of all previous attempts by China to develop a national jet-which have all been unsuccessful- and the recent history of high-tech industries where China represented the world's largest market and there was a national interest for technology transfer.

Under the changes in financial liberalization and internationalization, the loan quality of the financial market is often degraded due to incomplete financial system or man-made causes. The outcome of which is non-performing financial asset which may affect the economic stability of a country. Worst of all, it may even have the domino effect and affect the entire world. Review the Asian financial crisis in 1997, the main causes are incomplete financial system, worsened asset quality and insufficient financial supervision which resulted in low load quality, high rate of non-performing loan and huge bad loan amount. Moreover, the main reason that caused subprime mortgage storm in America, which triggered shock, fear and panic in international financial market in summer 2007, is bad supervision mechanism of financial products derived from subprime securitization. It does not matter what the causes of the financial crisis and its product, non-performing asset, are, in order to stabilize the economical and financial order, dealing with non-performing assets of financial institutions is the first mission for many countries in the world. After the reform and opening-up policy is implemented in China in 1979, due to the transformation of the economy and the changes in the financing system, the financial system in China is reformed. Examples are State-owned commercial bank shareholding transformation and State-owned enterprise shareholder structure reform. In 1999, China learnt a lesson from the Asian financial crisis. While concerning about China’s economic and financial development, the State Council decided to setup state-owned sole-source non-bank financial organizations, specializing in dealing with bad loans. Therefore, the Asset Management Company such as Cinda, Huarong, Great Wall, Orient are established one after another to deal with the bad loans of China Construction Bank, Bank of China, Agricultural Bank of China and Industrial and Commercial Bank of China. The main objectives of this paper is to understand the financial development history of China, the reform in financial organizations, the regulations of Asset Management Company and its operation, through discussing the process of the financial system reform, the origin of the establishment of the Asset Management Company, the regulation implication and the framework operation. Moreover, the policy orientation in terms of sustainable development of financial asset management companies is also explored. Hopefully the results of this paper can be used as references for companies which are going into the Chinese financial market after the cross-strait financial policy and the MOU are signed.

Abstract:
This chapter explores the practical entanglement of questions of public and private international law through an examination of the history of ten commercial aircraft belonging to Kuwait Airways Corporation. The aircraft were seized by Iraq after the unlawful 1990 invasion of Kuwait, flown to Baghdad, and handed over to Iraqi Airways. Proceedings seeking return of the aircraft and damages were commenced by Kuwait Airways against Iraqi Airways in the English courts, a further saga which led to more than thirty reported cases, including a remarkable five decisions of the House of Lords. The dispute raised a range of issues, including questions of jurisdiction, state immunity, and perhaps most significantly the potential for public international law to be given effect through domestic private law proceedings, in this case as a source of public policy denying effect to acts of Iraqi law which were contrary to UN Security Council resolutions.

Abstract:
The AP1000® pressurized water reactor (PWR) is the first and only Generation III+ nuclear power plant to be granted design certification by the United States Nuclear Regulatory Commission. The initial deployment of this technology has been the construction of dual AP1000 units in each of two coastal sites in the People’s Republic of China (PRC), at Sanmen (Zhejiang Province) and Haiyang (Shandong Province). The contracts for these units were framed to support the PRC’s intention to achieve self reliance in its nuclear supply infrastructure. Westinghouse is implementing its innovative supply chain strategy, “We Buy Where We Build”™, to promote the technology transfer and increasing levels of localization needed as each unit is constructed. Since the initial contract award in 2007, the Westinghouse Consortium and the purchasers, State Nuclear Power Technology Corporation of China (SNPTC), the Shandong Nuclear Power Company (SDNPC), and the Sanmen Nuclear Power Company (SMNPC) have worked in harmony to build the units using advanced modular construction techniques that reduce construction timescales and associated risks. First-of-a-kind (FOAK) plant components have been manufactured and delivered, including reactor vessels, steam generators, and other safety equipment. With construction and equipment installation in the final stages, the planning and implementation of the pre-operational testing, system turnover, and commissioning are now underway to prepare for fuel load and future commercial operation.

Full text
Abstract:
The T407/GLC38 turboprop/turboshaft engine is a 6000 shaft horsepower (SHP) class gas turbine engine currently under joint development by Textron Lycoming of Stratford, Connecticut, and GE Aircraft Engines of Lynn, Massachusetts, with Bendix Control of South Bend, Indiana, a division of Allied Signal; Ruston Gas Turbines Limited of Great Britain, part of GEC ALSTHOM; and Steel Products Engineering Company (SPECO) of Springfield, Ohio. The powerplant is derived from the highly successful GE27 Modern Technology Demonstrator Engine (MTDE) program, which was conducted under the auspices of the U.S. Army in the mid-1980s. The T407 turboprop is currently under development for the U.S. Navy’s new P-7A anti-submarine warfare (ASW) aircraft. The P-7A will replace the P-3 and is under contract to Lockheed Aeronautical Systems Company (LASC). A T407 turboshaft model is also in development. The GLC38 commercial turboprop version, planned for both business and commuter aircraft, draws considerably on lessons learned through GE and Textron Lycoming’s extensive commercial experience, thereby ensuring the latest state of the art in maintainability, life, reliability, and ease of operation. The T407/GLC38 engine development program, scheduled for completion in December 1991, is uniquely defined to meet the stringent requirements of both Federal Aviation Administration (FAA) regulations and Military Specification MIL-E-008593E. The engine’s primary identity will be commercial, however, as per agreement with the U.S. Navy. The engine’s gas generator core is also part of a joint venture between the Garrett Engine Division of Allied Signal Corporation and GE. Garrett is responsible for developing the fan and power turbine for a new generation turbofan engine, the CFE738. This paper describes the key features of the T407/GLC38 engine design, performance, and development program.

Under the U.S. Dept. of Energy (DoE) funded Ceramic Turbine Engine Demonstration Project (CTEDP), AlliedSignal Engines is addressing remaining critical concerns slowing the commercialization of structural ceramics in gas turbine engines. These issues include demonstration of ceramic component reliability, readiness of ceramic suppliers to support ceramic production needs, and development of ceramic design technologies. The AlliedSignal/Garrett Model 331-200[CT] auxiliary power unit (APU) is being used as a ceramics test bed engine. The first-stage turbine blades and nozzles were redesigned for ceramic materials, employing design methods developed during the earlier Dept. of Energy/National Aeronautics and Space Administration (DoE/NASA)-funded Advanced Gas Turbine (ACT) and Advanced Turbine Technology Applications (ATTAP) programs. The fabrication processes for these components provide the framework for demonstration of ceramic manufacturing process scale-up to the minimum level for commercial viability. Ceramic engine components have been fabricated and are now being evaluated in laboratory engine testing. This testing is helping to refine the component designs and focus the development of ceramic component technologies. Extended engine endurance testing and field testing in commercial aircraft is planned, to demonstrate ceramic component reliability. Significant progress was made during 1996 in the ceramic component manufacturing scale-up activities. The CTEDP ceramics subcontractors, AlliedSignal Ceramic Components (Torrance, CA) and Kyocera Industrial Ceramics Corporation (Vancouver, WA) demonstrated increased capacity and improved yields of silicon nitride materials. Planned ceramic turbine nozzle manufacturing demonstrations were initiated by both companies. Ceramic design technology was further refined in several areas. Work continued in defining boundary conditions for impact modeling of ceramic turbine engines, including completion of a three-dimensional trajectory analysis for combustor carbon particles in the engine flowpath. Contact rig tests and supporting analyses helped define the effectiveness of compliant layers in reducing ceramic turbine blade attachment contact stresses, and the results are aiding the evolution of more effective compliant layer configurations. This work supported evaluation of various ceramic turbine blade attachment designs in subelement and engine tests. Thin-film strain gage technology for measuring vibratory levels at high temperatures was successfully applied on ceramic turbine blades. Ceramic materials were screened for susceptibility to cyclic hot corrosion fatigue at the conditions affecting turbine blades. Stress rupture testing in support of the proof test methodology development was completed. Engine endurance tests with ceramic turbine nozzles accumulated over 482 additional hours of successful operation. Ceramic turbine blades were successfully demonstrated in over 190 hours of engine operation. This work brought the combined ceramic component engine test experience to over 1500 operating hours. Work summarized in this paper was funded by the DoE Office of Transportation Technologies, as part of the Turbine Engine Technologies Program, and administered through Fiscal Year 1996 by the NASA Lewis Research Center, Cleveland, OH under Contract No. OEN3-335.
