Resumo: | The aviation industry is an essential element of today’s global society and thus cannot ignore the public concern about the global warming and the environmental issues as well as the global economy and fuel prices. The actual green thinking and the new policies to protect the environment promoted the creation of some aeronautical environmentally friendly projects. They are meant to create new and cleaner solutions looking for a way to reduce the environmental footprint of aviation industry. These considerations involve the development of new aircraft concepts with lower pollutant emissions and fuel consumption. Consequently, this study aims to analyze the viability of a propfan engine with the introduction of a heat regenerator. According to several authors, the propfan engines are more efficient than the current turbofans and the introduction of heat regenerators in the gas turbines engines reduces its specific fuel consumption. Therefore, the combination of both propfan engines and heat regenerators may be a viable solution to reduce the specific fuel consumption in the current engines even further. The main purpose of this research Thesis is to analyze if this new engine concept could be a “greener” substitute to the current turbofans. This work consists in the comparison of three different engine configurations: a current turbofan; a conventional propfan and a regenerated propfan engine. The analysis is performed to show the influence of engine parameters in specific fuel consumption and specific thrust. The use of the heat regenerator could be justified if the reduction of the SFC and the increase of specific thrust are worthwhile considering the extra weight of the heat exchanger. |

O actual pensamento “verde” e as novas políticas de protecção ambiental promoveram a criação de alguns projectos aeronáuticos amigos do ambiente. Estes projectos são destinados à criação de novas e melhores soluções procurando reduzir a pegada ambiental da indústria da aviação. Estas considerações envolvem o desenvolvimento de novos conceitos de aeronaves com menores emissões poluentes e consumo de combustível. Assim sendo, este estudo visa analisar a viabilidade de um motor propfan incorporado com um regenerador de calor. De acordo com vários autores, os motores propfan são mais eficientes que os actuais turbofans e a introdução de regeneradores de calor em turbinas de gás reduz o seu consumo específico de combustível. Assim sendo, a combinação de ambos pode ser uma solução viável para uma redução ainda maior do consumo específico nos actuais motores. O principal propósito desta tese é analisar se este novo conceito de motor poderá ser um substituto mais amigo do ambiente dos actuais turbofans. Este estudo consiste na comparação de três diferentes configurações de motores: um actual turbofan; um propfan convencional e um propfan incorporado com regenerador de calor. A análise é feita de modo a perceber a influência dos parâmetros do motor no consumo específico de combustível e na tracção específica. O uso do regenerador de calor pode ser justificado se a redução do consumo específico de combustível e o aumento da tracção específica valerem a pena, tendo em conta o peso extra do regenerador.Brojo, Francisco Miguel Ribeiro ProençauBibliorumFerreira, Carolina da Silva2015-06-30T14:05:44Z201320132013-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.6/3673TID:201005301enginfo: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:RCAAP2023-12-15T09:40:10Zoai:ubibliorum.ubi.pt:10400.6/3673Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T00:45:02.068608Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
