Resumo: | In recent years, the interest in morphing technologies has been continuously growing. Many designs have been developed, but some are very complex to manufacture. The main goal of this dissertation is to present the development of a wing design with a morphing trailing edge that is easy to manufacture and control while allowing the execution of appropriate aerodynamic studies in a wind tunnel. Using computer-aided design and 3D (Three-dimensional) printing, a wing that is simply controlled with easy-to-use hardware is developed, manufactured, and studied using flow visualization and force acquisition. The whole developing steps are described in detail, as well as all the calibration processes of the required equipment to reproduce the final result, in order to enable others to proceed with further investigation using the present design. Considering initial studies, flow visualization showed that the presence of curvature delays stall when compared to the non-deflected configuration, where flow separation starts right at the leading edge. Also, the increase in deflection translates into an increase in the size of the wake, but not having a significant impact on the location of flow separation. In terms of force measurements, curvature plays an important role regarding lift enhancement, as well as substantially delaying wing stall when combining angle of attack with no flap deflection with trailing edge deflection. This design will allow for a wide range of studies to be performed, such as comparisons with conventional flap configurations to verify the performance of both systems, but also the study of unsteady conditions, including the dynamic motion of the trailing edge deflection, which can offer insights concerning aerodynamic surfaces design. |

Muitos designs têm vindo a ser desenvolvidos, com diferentes níveis de complexidade no que diz respeito à fabricação. O principal objetivo desta dissertação é apresentar o desenvolvimento de uma asa com bordo de fuga deformável, de fácil fabrico e controlo, e que permita a execução de estudos aerodinâmicos em túnel de vento de forma viável. Utilizando ferramentas de desenho computacional e impressão 3D, uma asa controlada de forma simples através de componentes básicos é desenvolvida, fabricada e estudada recorrendo a visualização do escoamento e medição de forças. Todo os passos de desenvolvimento são descritos em detalhe, bem como toda a calibração dos equipamentos necessários para reprodução do resultado final, de forma a permitir que outros procedam com uma investigação mais aprofundada da matéria recorrendo ao design apresentado. Considerando alguns estudos iniciais, a visualização do escoamento mostrou que a presença da curvatura retarda a ocorrência de perda quando comparada à configuração simétrica, onde a separação começa logo no bordo de ataque. Além disso, o aumento da deflexão traduz-se num aumento do tamanho da esteira produzida, apesar de esta não ter uma reflexão significativa na posição onde o escoamento separa. Relativamente à medição de forças, verifica-se que a curvatura desempenha um papel importante no aumento da sustentação, bem como atrasa substancialmente a entrada em perda da asa, quando se combina ângulo de ataque inicial com deflexão do bordo de fuga. Este design permitirá realizar uma ampla gama de estudos, tais como comparar com configurações convencionais de flaps para verificar o desempenho de ambos os sistemas, mas também o estudo de condições dinâmicas, incluindo movimentos repetitivos de deflexão do bordo de fuga, que poderão oferecer uma nova configuração no design de superfícies aerodinâmicas.Silva, André Resende Rodrigues dauBibliorumPinho, João Correia de2023-11-23T11:27:38Z2023-03-022023-01-182023-03-02T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.6/13766TID:203390156enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-12-15T09:57:28Zoai:ubibliorum.ubi.pt:10400.6/13766Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T00:53:08.046835Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
