Abstract(s)
Com o progresso da tecnologia aeronĆ”utica, a deslocaĆ§Ć£o de pessoas e bens tornou-se bastante acessĆvel para variados pontos de mundo, com espaƧo de tempo muito reduzido.
Um dos motores essenciais deste avanƧo, concernente Ć mobilidade, Ć© o transporte aĆ©reo e a sua evoluĆ§Ć£o. Este tipo de transporte requer a mĆ”xima seguranƧa, sendo que um Ćŗnico acidente pode gerar centenas de vĆtimas. Atendendo a estas condiƧƵes, a qualidade dos pavimentos aeroportuĆ”rios Ć© de grande importĆ¢ncia para a seguranƧa da movimentaĆ§Ć£o das aeronaves em solo. Mas, por razƵes econĆ³micas e por vezes de espaƧo, perspetivas de novas construƧƵes perdem viabilidade comparativamente a soluƧƵes de reabilitaĆ§Ć£o.
A posiĆ§Ć£o geogrĆ”fica do aeroporto de Ondjiva faz com que seja um importante ponto de passagem entre a Ćfrica do Sul e a NamĆbia e, prevĆŖ-se que o nĆŗmero de voos que se efetuam no aeroporto cresƧa, sendo que o paĆs estĆ” numa fase de grande evoluĆ§Ć£o.
O presente trabalho visa o conhecimento do processo de dimensionamento para pavimentos aeroportuĆ”rios e soluƧƵes de correĆ§Ć£o para anomalias que possam apresentar, aplicando-os ao aeroporto de Ondjiva, em Angola. Atualmente, o aeroporto revela um grande desgaste das pistas de tĆ”xi, inadaptabilidade das cabeceiras face Ć s cargas estĆ”ticas a que sĆ£o submetidas e, largura insuficiente da pista para a aeronave de projeto, ou aeronave crĆtica, atendendo ao regulamento da ICAO (International Civil Aviation Organization). Para melhorar o conforto, a seguranƧa e eficiĆŖncia dos serviƧos aĆ©reos, o dimensionamento do aeroporto deve obedecer aos princĆpios e regras da ICAO.
Pretende-se tambĆ©m a modelaĆ§Ć£o de uma soluĆ§Ć£o de reforƧo para o pavimento existente, para que nĆ£o seja necessĆ”rio construir um aeroporto de raiz, minimizando custos.
ApĆ³s a realizaĆ§Ć£o do dimensionamento, foi estudada a sinalizaĆ§Ć£o horizontal e luminosa da pista, para que esteja em conformidade com as suas novas medidas.
With aeronautical technology development, people and goods movement has become quite affordable for different parts of world, in a small period of time. One of the key factors of this advance, as far as mobility is concerned, is the air transportation and its own evolution. This kind of transport requires maximum security systems, because a single accident can cause hundreds of victims. Given these conditions, the quality of airport pavements is truly important for the safety of aircraft ground movement. But, for economic and, sometimes, space reasons, prospects for new construction lose viability against rehabilitation solutions. The geographical position of Ondjiva airport makes it an important crossing point between South Africa and Namibia, and it is expected that the number of flights that are carried out at the airport will grow, once the country is in a phase of great evolution. The present work focuses the knowledge behind the sizing process for airport pavements and correction solutions for anomalies that may occur, applying them to the Ondjiva airport, in Angola. Currently, the airport shows great wear of taxiways, inadaptability of the headwaters face to static loads to which they are submitted, and insufficient lane width for the project aircraft, or critical aircraft, given the ICAO (International Civil Aviation Organization) regulation. To improve comfort, safety and efficiency of air services, the airport scaling must obey the principles and rules of ICAO. It is also intended to model a solution for enhancing the existing pavement, in a way that wonāt be necessary to build an airport from scratch, minimizing costs. After performing the scaling, horizontal and light signaling of the track was studied, so it is in line with its new measures.
