(2023-04-24) Abreu, Renan de Araújo; Moura, Alexandre Douglas Araújo de; Centeno González, Felipe Orlando; http://lattes.cnpq.br/9688427609049172; http://lattes.cnpq.br/3602476790054326; http://lattes.cnpq.br/1553803715502791
One of the pillars, currently, in a modern civilization is aviation and the mobility, ease and convenience that this technology provides to human beings. The pioneers of aviation began with the construction of scale models, called model airplanes, which will be treated in this work. One of the most important points in the construction of a model airplane are the engine and the propeller, also called powertrain set, in this work it will be possible to see how the performance of this set was determined for the construction of an unmanned aerial vehicle carrying cargo, Within the aero design project at the university, we are going to show how the Excel and Propeler Selector software were used to acquire the data of the performance curves that the aircraft should have starting from the data coming from the aerodynamics sector that delivers the lift and drag coefficients of the aircraft, among other parameters, all calculations were carried out in order to understand the performance of the aircraft in takeoff, cruise flight and landing conditions, always taking into account the FAR-Part 23 standard. The engine had already been defined as the OS model .61FX, as well as, the propeller was also determined to be the model with a diameter of 13” and pitch of 7”, being possible to determine the performance of the vehicle to fly with a total weight of 10 kg.
O cenário do hidrogênio verde: uma revisão como suporte ao recente interesse surgido em indústrias e governos na região

With the fight against climate change as one of the main drivers, the search for solutions that lead to economic decarbonization is increasing around the world. In this context, green hydrogen, called when produced from renewable sources of wind and solar energy, is considered one of the main alternatives, which has mobilized initiatives in several countries to develop it. However, there are still challenges to be overcome, mainly related to production costs that are still much higher than those of hydrogen obtained from fossil sources that emit greenhouse gases (GHG). Brazil has a competitive advantage for the production of green hydrogen, due to its strong potential for wind and solar energy, as well as the competitiveness of the energy generated from these sources in relation to other countries. In this sense, several national and international companies have expressed interest in investing in the Brazilian production chain of Green Hydrogen. Thus, a new industry is born in the country, opening spaces for the attraction of large investments, mainly in the Northeast Region, given its greater competitiveness in solar and wind generation. In view of this, this study sought to carry out a review of the general concepts of hydrogen, addressing its properties and characteristics, its use as a fuel, a review of the Hydrogen Economy, as well as economic aspects. Applications were seen in pilot projects, which prove the use of hydrogen as an energy vector in integrated production, storage and transport models. A brief history of the actions and initiatives in the world and in Brazil in favor of the development of the hydrogen industry is also made. In conclusion, Brazil emerges as a potential supplier of green hydrogen due to the great diversity of renewable sources.
Estudo de caso: Implantação do método de planejamento e controle da manutenção (PCM) como estratégia para o aumento da confiabilidade e disponibilidade dos ativos no setor de manutenção agrícola de uma usina de cana de açúcar da região Nordeste
(2022-05-24) Silva, Kerolly Thallya Pimentel Batista da; Centeno González, Felipe Orlando; http://lattes.cnpq.br/9688427609049172; http://lattes.cnpq.br/5671236699389554
This work is a case study that aims to demonstrate the importance of management in maintenance processes. Theoretical concepts that approach maintenance management in order to make the reader familiar with the subject and therefore portrayed in the practice of maintenance planning and control (PC) in the maintenance sector of a sugarcane sector implantation plant in the region North East. Through the computerized system announcements of the high-value company announcements of the high reliability of the chaotic reality of the low and the high unavailability of data generated by the cost and maintenance index of the maintenance of the maintenance of the cost and the high of the possible was the need for the sector to be responsible for maintenance management was verified. In this way, the maintenance planning and control sector (PCM) was planned, which is a maintenance area that strategically aims to process the processes of this segment. This study shows the importance of analyzing the performance indicators originated after the implementation of the PCM and as the case of decision making with greater precision and agility, resulting in an increase in the profitability of the organization.
Levantamento da liberdade de operação atual de biodigestores domésticos no Brasil
(2024-05-22) Santos, Damerson Vinícius Santana dos; Centeno González, Felipe Orlando; http://lattes.cnpq.br/9688427609049172; http://lattes.cnpq.br/0844925584480221
The population growth along with economic development has increased waste Production, however, waste treatment methods have not evolved at the same pace. Due to the high demand for waste treatment from households nowadays, biodigesters are becoming increasingly relevant as a potential technology capable of proper treatment, in addition to generating biogas and biofertilizer as by-products. However, this knowledge is still limited, so a survey of domestic biodigester models capable of meeting these demands is essential to disseminate this technology to the public. Therefore, the present work aims to survey the operational freedom of domestic biodigester models and the state of the art in this area, classify the researched models, and review patent research mechanisms. For this purpose, a study was conducted on search techniques used to apply appropriate filters, thereby reducing the amount of information and focusing on the subject at hand. Subsequently, an approach to the types of searches made in patent databases was conducted to reduce the number of patents and focus only on domestic biodigester models. Based on the research methods, a diverse set of domestic biodigester models was found, designed to meet the needs of both small households, as exemplified by the HomeBiogas model, and the requirements of a community of 100 people, as in the case of the Plug Flow model. It was observed that operational freedom varies depending on the information source, with scientific research having greater operational freedom and patent models having less. The combination of this knowledge resulted in the proposition of potential solutions for the treatment of waste produced in households, playing an important role in promoting sustainable practices and advancing environmental and social development.
