Esses veículos são hoje longamente utilizados em operações conjuntas de lançamento com diversos países. A aquisição de tecnologia, pelo IAE, possibilitou a concepção e o desenvolvimento do Veículo Lançador de Satélite - VLS - item fundamental dentro do Programa Espacial Brasileiro que está, atualmente em fase de qualificação em vôo. O CTA e seus institutos promoveram avanços tecnológicos no país, muitos em parceria com empresas nacionais. Na área de materiais, um grande investimento foi feito para permitir a produção, no Brasil, das estruturas dos motores em aço 300m. O envolvimento das indústrias mecânicas e químicas na produção do mais simples componente é por si só fator de desenvolvimento. Muitos materiais de uso espacial devem ser manipulados com cuidados inusitados; as tolerâncias dimensionais ou das propriedades fisico-químicos obrigam ao treinamento de mão de obra e a seleção rigorosa dos métodos de inspeção e de fornecedores. Este trabalho apresenta um modelo conceitual de gestão sistêmica baseado em pensamento estratégico ideal para definir os objetivos estratégicos de uma organização de pesquisa e desenvolvimento tecnológico no setor aeroespacial. O modelo estabelece uma integração sistêmico dos modelos de gestão de conhecimento, gestão de competências e gestão da qualidade / Abstract: In the competitive world of these days, a system or organization has success only if it presents a differential competitive character in terms of continuos innovation. lnvesting in research and development (R&D) is a very important necessity for survival. The main Brazilian lnstitution for research and aerospace project development, Instituto de Aeronáutica e Espaco - IAE, from Centro Técnico Aeroespacial- CTA started its activities in 1969, developing sounding rockets. CTA and its institutes have promoted technological advances in the country, lots of them in association with national companies. In the last ten years, CTA-IAE is facing different kinds of problems like: lack of budget from Federal Government, boycott of imported products, retirements, low salaries, low motivation and lack of future perspectives. All these problems compromise the surviving and the existence of the Brazilian (R&D) organizations. This work presents a conceptual model of the strategic management of the (R&D) organization, with the intention of increasing the survival chances. It also describes a model for strategy methodology based on theoretical aspects, where Prahalad and C.K. Hamel, define the ideal strategy based on Core Competence for the (R&D) organization. The development of an efficient organization change is based on the theories of Henry Metzberg, Broce Ahlstrand and Joseph Lampel. Knowledge Management (KM) assessment is used in the human resources development. The model was built supported by "State of Art" literature and was tested in the Aerospace organization CTAlIAE in Brazil. The model will be controlled by the roles and criterions of Malcon Baldrige and PNQ (Prêmio Nacional de Qualidade). The final product of the work will be a systematic model for strategy management of integration of (R&D) organization / Doutorado / Materiais e Processos de Fabricação / Doutor em Engenharia Mecânica

In the aviation industry, purchasing departments spend approximately 80% of revenues on procurement. Additionally, 62% of companies experience unforeseen expenses or hidden costs in the procurement process. Grounded in a conceptual framework of activity-based costing, the purpose of this case study was to explore strategies used by 5 upper-level supply chain management leaders at a maintenance repair and overhaul company in the aviation industry in the Southeastern United States to accurately forecast procurement costs. Data collection included 5 semistructured interviews, company documents, and annual reports. Through thematic analysis, the major themes that emerged from the data analysis were accuracy, competitive advantage, improved corporate performance, and improved total cost analysis. The findings may contribute to social change in the Southeastern region of the United States. The aviation industry is experiencing competition from low-cost countries and the economy of the region and hundreds of families and educational institutions depend on the success of the companies in the region for sustainability.

The sponsor of the thesis is the Composite Unit of AIRBUS Nantes plant, which manufactures aircraft composite. The basic process to manufacture composite parts is to lay-up raw composite material on a tool and involves very costly means and raw material. This process can be modeled as a two-stage hybrid flow shop problem with specific constraints, particularly prescription constraints on the jobs. This thesis restates the practical problem as a scheduling problem by doing hypotheses and restrictions. Then, it designs a mathematical model based on time-indexed variables. This model has been implemented in an IP solver to solve real based scenarios. A heuristic algorithm is developed for obtaining good solutions quickly. Finally, the heuristic is used to increase the execution speed of the IP solver. This thesis concludes by a discussion on the advantages and disadvantages of each option (IP solver vs. heuristic software) for the sponsor. / Master of Science

Thesis (MScEng (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The development of light and sti aerospace structural panels is very important in the aerospace industry, e.g. a lighter satellite requires less fuel to launch it into space which in turn saves money for the owner of the satellite. This thesis describes the design, optimisation, manufacturing and testing of a ribbed light alloy core - carbon bre face sheets, sandwich-type, satellite panel operating at launch loading conditions (115 m/s2 accelerations and requiring a minimum structural natural frequency of 90 Hz) to determine the optimum sti ness per mass ratio of the panel. The panel layout was based on a satellite panel designed by SunSpace and Information Systems for the Sumbandila satellite. Only the black box mounting positions of the original panel were used in the optimisation of the new panel. The core of the evaluation panel was manufactured from aluminium (6082-T6). The carbon bre skins were manufactured from unidirectional high modulus carbon bre (K63712) in a [0/90/0] wet layup with the 0± direction in the longitudinal direction of the panel. A three-dimensional model of the panel consisting of 3D wedge elements and containing all the boundary conditions was modelled with the use of the nite element software MSC Patran. The model was optimised with the use of optimisation software Genesis to locate the rib positions. Genesis removes all the elements containing the least amount of stress; only 30% of the core elements were kept while restricting the elements to form an extruded con guration (for milling machining) throughout the thickness of the panel. The rib elements remaining were replaced in MSC Patran by shell elements and the shell element thicknesses were optimised with the use of Genesis to ensure the lightest and sti est possible structure. The optimised rib thicknesses were imported into MSC Patran and the numerically optimised model could then be analysed with MSC Nastran. The numerical model was converted into a manufacturable structure and the core was machined from a solid aluminium sheet. The ribs were machined in the shape of an Ibeam to allow for minimum weight and a su cient bonding area for the two carbon bre face sheets. Elevated circular surfaces, protruding through the carbon bre sheets, were machined in the position of the black box mountings to allow for better heat transfer away from the black boxes. The carbon bre face sheets were bonded to the metal core (3M Scotch-Weld 9323 B/A). The nished panel was put through various tests to determine whether it is suitable for use in the aviation industry. The tests included modal testing, random vibration testing and temperature testing to determine if the structure is durable enough for use in satellites. The test results are promising and show that a substantive amount of money can be saved by reducing the mass on the structure. By using optimisation software and ribbed light alloy - carbon bre face sheets sandwich structures the performance of the structures can be improved without adding mass to the structure. / AFRIKAANSE OPSOMMING: Die ontwikkeling van ligter en stywer lugvaartstruktuur panele is baie belangrik in die lugvaart-industrie, bv. 'n ligter satelliet benodig minder brandstof om tot in 'n wentelbaan lanseer te word. Dit bespaar sodoende lanseerkostes vir die eienaar van die satelliet. In die verslag word die ontwerp, optimering, vervaardiging en toets van 'n gewebde, ligte allooi kern - koolstofveselvel, saamgestelde materiaal, satelliet struktuurpaneel wat onderwerp word aan lanseer belastingstoestande van ongeveer 115 m/s2 versnellings ondersoek. Die tegnieke word gebruik om die optimale styfheid per eenheidsmassa-verhouding te bepaal. Die paneel benodig 'n minimum strukturele eerste natuurlike frekwensie van 90 Hz. Die basiese paneel uitleg is verkry vanaf 'n satellietpaneel wat deur SunSpace and Information Systems ontwerp is vir die basisplaat van die Sumbandila satelliet. Die enigste geometrie wat van die oorspronklike struktuur behou is om die nuwe struktuur te optimeer is die vashegtingspunt-posisies van die swart-kassies. Die kern van die ge-optimeerde struktuur is vervaardig uit gemasjieneerde aluminium (6082-T6). Die koolstofvesel-velle is vervaardig uit enkelrigting hoë-modulus koolstofvesel-doek (K63712). Die oplegging is gedoen met 'n nat-opleggingsproses waar die drie lae van elke vel 'n [0/90/0] oriëntasie het met, die 0± lae in die langsrigting van die paneel. 'n Drie-dimensionele eindige element model van die paneel is geskep met behulp van die MSC Patran sagteware pakket met die model hoofsaaklik opgebou uit 3D wig-elemente. Al die lanseertuig vashegtingsrandwaardes is in die eindige element model ingebou. Om die web posisies te bepaal is die Genesis optimeringsagteware pakket gebruik. Verskeie ontwerpsvoorwaardes is gespesi seer waaraan die optimeringsproses moes voldoen. Slegs 30% van die wig-elemente mag behoue bly in die optimeringsproses en al die elemente deur die dikte van die paneel moet of behou of verwyder word. Dit verseker dat die resultaat masjieneerbaar is met 'n freesmasjien. Die oorblywende wig-elemente is in MSC Patran vervang met dop-elemente. Die dopelemente se diktes is ge-optimeer met Genesis om die ligste en styfste struktuur moontlik te kry. Die ge-optimeerde dop-element diktes is in die MSC Patran model ingetrek. Die numeries ge-optimeerde model is daarna met behulp van MSC Nastran ge-analiseer. Nadat die numeriese model omgeskakel is in 'n vervaardigbare struktuur is die kern gemasjieneer uit 'n soliede blok aluminium. Die webbe is ontwerp en vervaardig in 'n I-balk vorm. Dit laat toe dat die webbe 'n minimum gewig en genoegsame area het waarop die koolstofvesel velle geheg kan word. Verhewe vlakke is gemasjieneer op die aluminium kern in die posisies van die swart-kassie vashegtingpunte. Hierdie verhewe vlakke steek deur die koolstofvesel-vel aan die kant waar die swart-kassies vasgeheg word. Dit verseker 'n metaal-op-metaal verbinding tussen die kern en die swart-kassies vir beter hittegeleiding. 3M Scotch-Weld 9323 B/A epoksie is gebruik om die koolstofvesel-velle aan die aluminium kern te heg. Die voltooide struktuur is aan 'n reeks toetse onderwerp om te bepaal of dit geskik is om in die ruimtevaart-industrie gebruik te kan word. Dit sluit modale toetse, lukrake vibrasie toetse en temperatuursverandering toetse in. Die toetsresultate sal bepaal of die struktuur duursaam genoeg is om in satelliete gebruik te word. Die toetsresultate is belowend en dui daarop dat deur massa te bespaar op die struktuur, 'n aansienlike bedrag op satelliet lanseer-kostes bespaar kan word. Deur optimeringsagteware tesame met gewebde ligte allooi kern - koolstofvesel vel, saamgestelde materiaal strukture te gebruik kan die werksverrigting van die strukture verbeter sonder dat massa bygevoeg word.

A estratégia da política pública de longo prazo para o setor aeroespacial compreende, historicamente, uma variável fundamental para organização e desenvolvimento dessas atividades em todos países que contam com esses segmentos industriais, inclusive o Brasil. A partir de meados dos anos 2000, a retomada das políticas industriais setoriais, como diretriz para o desenvolvimento econômico no Brasil, marcou um novo cenário em relação aos anos 90, com a implementação de estratégias baseadas nas características e nos desafios para as atividades. Essas novas diretrizes envolveram também o setor aeroespacial. O tema do presente trabalho é a estratégia para o Setor Aeroespacial Brasileiro, entendida como a apreciação das escolhas e objetivos da política industrial. O problema de pesquisa, por sua vez, consiste na análise comparada da estratégia brasileira e na formulação de considerações para uma avaliação abrangente da política, tendo como referência a experiência canadense. O objetivo do estudo é comparar a concepção estratégica para o setor aeroespacial estabelecido no Brasil pela Política de Desenvolvimento Produtivo (PDP) em 2008 em relação National Aerospace and Defence Framework (NADF), que foi instituída no Canadá, em 2005. A justificativa para escolha da referência canadense é fundada nas semelhanças em relação orientação da produção e características configuração setorial. Nesse contexto o estudo descreve a evolução e apresenta as especificidades do sistema de produção aeroespacial do Brasil e do Canadá; analisa as diretrizes políticas e estratégias para o setor, empreendidas pelos países, tendo como referência os objetivos de política setorial; e compara os programas e ações para o setor, desenvolvidos no contexto da PDP (Brasil) e da NADF (Canadá). Entre as constatações derivadas da análise podemos destacar as diferenças no conceito de autonomia associados à políticas empreendidas no Brasil e no Canadá; a participação das médias empresas e das subsidiárias estrangeiras no tecido produtivo; e a configuração da infraestrutura e serviços de apoio entre os países. Particularmente, em relação às políticas, há diferenças importantes em relação aos objetivos; requisitos e forma de seletividade das ações; e articulação dos instrumentos para consecução dos objetivos. Entre as considerações críticas para avaliação da política no Brasil, formuladas com base experiência canadense, destacam-se a ausência de um projeto integrado para o setor aeroespacial e definição de metas em relação às variáveis básicas de performance da atividade industrial; o foco excessivo nos produtos e a pouca ênfase nos processos de construção de competências para inserção nas cadeias internacionais de valor; e a visão limitada dos elementos institucionais necessários para viabilizar a produção aeroespacial no longo prazo. / The strategy of long-term public policy for the aerospace sector comprises Historically, a key variable for organization and development of these activities in all countries that have these industry segments, including Brazil. From the mid 2000s, the resumption of sectorial industrial policies, as a guideline for economic development in Brazil, marked a new scenario for the years 1990, with the implementation of strategies based on the characteristics and challenges for the activities. These new guidelines also involved the aerospace sector. The theme of this work is the strategy for the Brazilian Aerospace, understood as the appreciation of the choices and goals of industrial policy. The research problem, in turn, is the comparative analysis of Brazil\'s strategy and the design considerations for a comprehensive policy, with reference to the Canadian experience. The objective is to compare the strategic design for the aerospace sector in Brazil established by the Production Development Policy (PDP) in 2008 for the National Aerospace and Defence Framework (NADF), which was established in Canada in 2005. The rationale for choosing the Canadian reference is based on similarities between production orientation and configuration features sector. In this context, the study describes the evolution and presents the system specifications in the aerospace in Brazil and Canada, examines the policy guidelines and strategies for the sector, undertaken by countries with reference to the objectives of sector policy, and compares the programs and actions for the sector, developed in the context of the PDP (Brazil) and NADF (Canada). Among the findings derived from the analysis can highlight the differences in the concept of autonomy associated with the policies undertaken in Brazil and Canada, and the participation of medium-sized enterprises and foreign subsidiaries in the productive fabric, and configuration of infrastructure and support services between countries. Particularly in relation to policies, there are important differences in relation to the objectives; requirements and form of selective measures, and articulation of the instruments for achieving the goals. Among the critical considerations for policy evaluation in Brazil, formulated based on Canadian experience, we highlight the lack of an integrated project for the aerospace and setting targets in relation to the basic variables of performance of industrial activity, the excessive focus on products and little emphasis on the processes of building skills for insertion in international value chains, and the limited vision of institutional elements needed to make production viable in the long term aerospace.
