English to Portuguese: Control functions / Funções de controle General field: Tech/Engineering Detailed field: Automation & Robotics
Source text - English Controlling an automated flow line is a complex problem, owing to the sheer number of sequential steps that must be carried out. There are three main functions that are utilized to control the operation of an automatic transfer system. The first of these is an operational requirement, the second is a safety requirement, and the third is convenience.
1. Sequence control. The purpose of this function is to coordinate the sequence of actions of the transfer system and its workstations. The various activities of the automated flow line must be carried out with split-second timing and accuracy. On a metal machining transfer line, for example, the working parts must be transported, located, and clamped in place before the work heads can begin to feed. Sequence control is basic to the operation of the flow line.
2. Hazard monitoring. This function ensures that the transfer system does not operate in an unsafe or hazardous condition. Sensing devices may be added to make certain that the cutting tool status is satisfactory to continue to process the working part in the case of a machining-type transfer line. Other checks might include monitoring certain critical steps in the sequence control function to make sure that these steps have all been performed and in the correct order. Hydraulic or air pressures might also be checked if these are crucial to the operation of automated flow lines.
3. Quality monitoring. The third control function is to monitor certain quality attributes of the working part. Its purpose is to identify and possibly reject defective working parts and assemblies. The inspection devices required to perform quality monitoring are sometimes incorporated into existing processing stations. In other cases, separate stations are included in the line for the sole purpose of inspecting the working part.
Translation - Portuguese O controle de uma linha de fluxo automatizada é um problema complexo, devido ao grande número de etapas sequenciais que devem ser realizadas. Existem três funções principais que são utilizadas para controlar a operação de um sistema de transferência automática. A primeira delas é uma exigência operacional, a segunda é uma exigência de segurança, e a terceira é uma conveniência.
1. Controle sequencial. O objetivo desta função é coordenar a sequência de ações do sistema de transferência e suas estações de trabalho. As diversas atividades da linha de fluxo automatizada devem ser realizadas em frações de segundos com cronometragem e precisão. Em uma linha de transferência de usinagem metálica, por exemplo, as peças devem ser transportadas, localizadas e fixadas no local antes que os cabeçotes de trabalho possam começar a avançar. O controle da sequência é básico para a operação da linha de fluxo.
2. Monitoramento de perigos. Esta função garante que o sistema de transferência não opere em condições inseguras ou perigosas. Sensores podem ser adicionados para garantir que o status da ferramenta de corte seja satisfatório para continuar a processar a peça no caso de uma linha de transferência do tipo usinagem. Outras verificações podem incluir o monitoramento de certas etapas críticas na função de controle de sequência para garantir que todas essas etapas tenham sido executadas e na ordem correta. Pressões hidráulicas ou de ar também podem ser verificadas se estas forem cruciais para a operação de linhas de fluxo automatizadas.
3. Monitoramento da qualidade. A terceira função de controle é monitorar certos atributos de qualidade da peça. Sua finalidade é identificar e possivelmente rejeitar peças e conjuntos defeituosos. Os dispositivos de inspeção necessários para realizar o monitoramento da qualidade são às vezes incorporados às estações de processamento existentes. Em outros casos, estações separadas são incluídas na linha com a única finalidade de inspecionar a peça.
English to Portuguese: A Brief History of Aircraft Structures General field: Tech/Engineering Detailed field: Aerospace / Aviation / Space
Source text - English The history of aircraft structures underlies the history of aviation in general. Advances in materials and processes used to construct aircraft have led to their evolution from simple wood truss structures to the sleek aerodynamic flying machines of today. Combined with continuous powerplant development, the structures of “flying machines” have changed significantly.
The key discovery that “lift” could be created by passing air over the top of a curved surface set the development of fixed and rotary-wing aircraft in motion. George Cayley developed an efficient cambered airfoil in the early 1800s, as well as successful manned gliders later in that century. He established the principles of flight, including the existence of lift, weight, thrust, and drag. It was Cayley who first stacked wings and created a tri-wing glider that flew a man in 1853.
Earlier, Cayley studied the center of gravity of flying machines, as well as the effects of wing dihedral. Furthermore, he pioneered directional control of aircraft by including the earliest form of a rudder on his gliders.
In the late 1800s, Otto Lilienthal built upon Cayley’s discoveries. He manufactured and flew his own gliders on over 2,000 flights. His willow and cloth aircraft had wings designed from extensive study of the wings of birds. Lilienthal also made standard use of vertical and horizontal fins behind the wings and pilot station. Above all, Lilienthal proved that man could fly.
Octave Chanute, a retired railroad and bridge engineer, was active in aviation during the 1890s. His interest was so great that, among other things, he published a definitive work called “Progress in Flying Machines.” This was the culmination of his effort to gather and study all the information available on aviation. With the assistance of others, he built gliders similar to Lilienthal’s and then his own. In addition to his publication, Chanute advanced aircraft structure development by building a glider with stacked wings incorporating the use of wires as wing supports.
Translation - Portuguese Uma Breve História sobre Estruturas de Aeronaves
A história sobre as estruturas de aeronaves está subjacente à história da aviação em geral. Os avanços nos materiais e processos utilizados na construção de aeronaves levaram à sua evolução, desde estruturas simples de treliça de madeira até as elegantes máquinas voadoras aerodinâmicas de hoje. Combinadas com o desenvolvimento contínuo dos motores das aeronaves, as estruturas dessas "máquinas voadoras" mudaram significativamente.
A principal descoberta de que “sustentação” poderia ser criada passando o ar por cima de uma superfície curva colocou em movimento o desenvolvimento de aeronaves de asa fixa e de asa rotativa. George Cayley desenvolveu um eficiente aerofólio curvado no início do século XIX, bem como planadores tripulados de sucesso no final daquele século. Ele estabeleceu os princípios do voo, incluindo a existência de sustentação, peso, impulso e arrasto. Foi Cayley quem primeiro empilhou as asas e criou um planador de três asas que fez um homem voar em 1853.
Antes, Cayley estudou o centro de gravidade dessas máquinas voadoras, bem como os efeitos da asa diédrica. Além disso, ele foi pioneiro no controle direcional de aeronaves, incluindo o leme em seus planadores. No final de 1800, Otto Lilienthal construiu planadores a partir das descobertas de Cayley's. Ele fabricou e pilotou seus próprios planadores em mais de 2.000 voos. Seu avião de madeira e tecido tinha asas projetadas a partir de um extenso estudo das asas dos pássaros. Lilienthal também padronizou o uso de superfícies verticais e horizontais atrás das asas e da estação de piloto. Acima de tudo, Lilienthal provou que o homem podia voar.
Octave Chanute, um engenheiro aposentado de ferrovias e pontes, esteve ativo na aviação durante a década de 1890. Seu interesse era tão grande que, entre outras coisas, ele publicou um trabalho definitivo chamado "O Progresso em Máquinas Voadoras". Este foi o ponto culminante de seu esforço para reunir e estudar todas as informações disponíveis sobre aviação. Com a ajuda de outros, ele construiu planadores semelhantes aos de Lilienthal e depois os seus. Além de sua publicação, Chanute gerou um avanço no desenvolvimento de estruturas da aeronave, construindo um planador com asas empilhadas e incorporando o uso de fios como suportes de suas asas.
