Performance and emissions of a gas turbine engine using ox tallow ethyl-ester blended with kerosene

The performance and emissions behavior of a Rover 1S/60 turboshaft engine when operated with several blends of aviation kerosene and ox tallow ethyl-ester are shown in this article. The tests were performed with a compressor shaft coupled to an hydraulic dynamometer where data of power and mass fuel flow were collected to determine the brake specific fuel consumption. A flue gas analyzer was positioned at the exhaust duct to collect oxygen, carbon dioxide, carbon monoxide and nitrous oxides. An increase in the specific fuel consumption was observed due to the lesser lower heating value of the most oxygenated blends. However, reductions of CO, CO2 and NO (x) have been observed and no-significant ill effects have occurred in the turbine operation.

Estudo de um método para simulação e teste de sistema de freio

The brake system of a Formula SAE car has determinant character in the quality of the project. Any flaw in the design of the brakes, the vehicle is rejected for the competition. The project well done, and its smooth operation, depends on some variables that should be studied and linked to the brake components, as needed by the vehicle. After the calculations, the components were defined according to commercial availability. So it is interesting simulation of braking when the vehicle will be submitted before the implementation of the brake system, saving time and cost. This project also enable the comparison between components from different brands. This work shows the study of a method that would allow simulate and test the brake system in an upcoming project for a bench test

Aplicação dos conceitos de RCM e a ferramenta FMEA no aumento de confiabilidade em equipamentos de uma indústria química

The growing demand for quality at competitive prices and fast production process put to the test function in the industrial Maintenance. The need for equipment with high availability to fit this fierce competitiveness makes maintenance becomes essentially reliable. Despite this current context, many companies still have an old view of maintenance, focused only on corrective services, and proposals for change are often neglected due to the sense of urgency day to day. Thus, this study aims to demonstrate through theoretical applicability of simple tool, but of great value in increasing reliability within the maintenance sector of an industry, applying the concepts of Reliability Centered Maintenance – RCM and Analysis tool Failure Modes and Effects – FMEA in equipment of a chemical company directly involved in the manufacturing process of the brake fluid, which this product is used in vehicles around the country. That way, you can identify the types, occurrence and criticality of each failure and evaluate assertively decision making for each device, avoiding unnecessary downtime and potential failures of the same

Projeto CHRONOS - desenvolvimento e aplicação de um sistema de freios automotivo

The automobilist Market is more competitive each day, with new products developed by great technological innovations, daily challenging new concepts of Engineering. This monograph aims to explain the development of a brake system project completely, with emphasis on preliminary calculations made from a worksheet in Excel, for a better understanding of the components, which can be improved further in order to achieve the goals of company. It is through the preliminary calculations that we can have a reasonable first system estimate. The whole set is then analyzed for performance, cost and mass by competitors benchmarking. In terms of confidentiality, all data is fictional, but viable. The motivation for this study is approach an extracurricular topic, which essence is designing, base of engineering. The results obtained in software and field tests prove the validity of the study and assist in the continuous improvement of product development

Redução do tempo de ciclo baseado na produção enxuta em uma rémontagem de tubos de freios e combustível

In today's competitive environment of automakers, it is essential to obtain the highest efficiency of the production process. This paper presents a study in a pre-assembly of brake pipes and fuel of a vehicle where the value stream maps and information (VSM – Value Stream Mapping) were designed in order to improve the process by reducing the Lead Time Production of a product, reducing waste and decrease time between processes. This work can be divided into three stages, the first building the VSM of the initial state, the second VSM of the proposed state and finally the VSM than was actually performed and to present the gains were achieved effectively. The proposed VSM would lead to a gain of 54% in lead time and 61% in processing time, since the VSM implemented had gains of 47% in lead time and 48% in processing time even without major investments as originally proposed. Concluding that even without big investment, using the techniques of lean manufacturing is possible to achieve high levels of process efficiency

Analise de desgaste em materiais aplicados em discos de freio

Baja SAE competitions challenge engineering students to design and build offroad vehicles, preparing them for the competitive job market. This monograph aims to study a part of the braking of a Baja SAE vehicle system, the brake disc. Giving attention to the wear suffered by discs of two different materials, steel 1045 and stainless steel 304, helping the team Piratas do Vale Bardahl in the best selection between them. Braking tests were performed on a test bench. Both discs have suffered the same braking conditions. Brake pads material, brake line pressure, braking time, number of braking, were parameters which were repeated in the testing of different types of disk, in order to ensure a high power comparison between the obtained data. Before and after the disk tests were weighed and measured, to make a comparison. After the brake tests, the disks were subjected to hardness and surface roughness testing. With the data collected and observations made in the worn parts, the comparison between these two materials was made, obtaining a selection of the best material for the team. The tests showed that steel 1045 has more advantages, compared to stainless steel 304, when applied to brake discs, on the tested conditions
