How Did Boeing 787 Improve The Fuel Economy

Nowadays, the growing public awareness of the impact of aircraft emissions on the environment forces the aviation stakeholders to search for environmentally friendly solutions. The relation between aircraft emissions and climate change relies heavily on fossil fuels. Indeed, when an aircraft burns fuel, several pollutants that alter the chemical composition of the atmosphere are produced and released into the sky. One of the principal pollutants emitted from aviation is the carbon dioxide (CO2); a greenhouse gas well known for its contribution to global warming. For each kilogram of fuel consumed, a typical engine of a commercial aircraft produces on average 3.15 kilograms of CO2 [X]. In comparison to other modes of transport, the aviation industry is responsible for 2.5% of global carbon dioxide emissions [X]. Although this percentage may seem relatively small, it has in reality a disproportionate large impact on the environment. Indeed, around 80% of aviation emissions are emitted from flights of over 5,000 feet, and as pointed out by Lee et al. in [X], the impact per kilogram of CO2 emissions at high-altitudes on climate change is about twice that of emissions at ground-level. Faced with this awareness, the International Air Transportation Association (IATA) has recognized the need to address the global challenge of climate change and has set the ambitious goal of reducing the aviation carbon footprint by 50% by 2050, relative to 2005 levels [X].

The first production electric cars were produced around the early 1900s and they were tremendously more popular than cars with gasoline engines. They eventually died out in the 1920s because of the decrease in cost of the gasoline engine. Even though electric cars faded away in the 1920’s they are making a comeback now due to the many benefits of an electric car over the traditional gasoline engine. Because of the rapid evolution of the electric car raises concern on the future of the gasoline engine, also the rise in popularity of the electric car because of environmental and other reasons. The future of electric cars will negatively affect the longevity of the gasoline engine because of the advancement of technology (or the area of) in

In the article, “ Why the Gasoline Engine Isn’t Going Away Anytime Soon,” Joseph B. White writes about the reality of the old school, yet productive ways how the internal-combustion engine is going to stay in the competitive market. While at the same time he describes the change for the industry is coming just at a gradual slow pace. For years environmentalists and energy saving specialists could not accomplish what high oil prices did in just a couple years. Changing the game of auto makers focus to make improvements to their engines. The idea of changing from oil to electricity is possible but there is few chances of it succeeding until the future. The author states that cars powerful enough to serve more than one function are the basic need

In this chapter, it was tried to describe a new perspective for the future aviation industry fuel provision. Considering serious constrictions ruled by CAAA, it is of high probability that Avgas, the current conventional aviation fuel, will be forbidden because of air polluting problem it causes and the fact that it contains considerable amounts of lead element which is hazardous. Ethanol, as a green biofuel, has a promising production potential to be introduced as an alternative fuel according to the current aviation market capacity. Advantages and disadvantages of ethanol usage as an aviation alternative was fully described. The necessary airplane engine modification was mentioned to compensate some of ethanol drawbacks along with some case

Three main areas Computational Fluid Dynamics, Alternative engines and advanced materials are considered in research.

In 2012, the amount of petroleum used every day skyrocketed to an all-time high of 88.9 million barrels used per day. (Energy, 2013) With such a huge dependency on fossil fuels today, it is critical that the world finds ways to increase efficiency to a maximum. That is why in most industries, new technology is always being produced that increases the efficiency of the machines, for example the aircraft industry. By simply adding afterburners in a jet turbine, excess jet fuel is not wasted, eliminating byproducts released into the atmosphere while gaining extra

The Majority of vehicles used to this day utilize gasoline for their primary source of fuel. Because of this, electric vehicles have faced a decline in the future of their industry due to natural physics that exists in the world. Although many of the electric vehicles offer benefits, petroleum vehicles naturally outperform the electric run vehicles. This is the result of the technology of electric vehicles due to its battery capabilities, performance, impact on the environment, and the financing of the car.

In the automotive world, efficiency and power are two elements of vehicle performance metrics that while important to many consumers and critics alike, appear to be elusive when in convolution with one another. In automotive history, good fuel efficiency equaled compromises in power and performance and vehicles with large displacements and torque usually had worse gas mileage. The exception to this rule were diesel engines, which managed to combine better efficiency than many four-cylinder gas engines while providing very high torque number for better performance. The main drawback that diesel’s faced was due to their stigma of being dirty, as they emitted more greenhouse gases including nitrous and sulfur oxides. Coupled with the stricter emissions that many states began to implement, primarily overseen by the EPA, it became harder for car manufactures to certify diesel engines for emissions while maintaining high fuel economy and power output figures. The emission control hardware and software in diesel vehicles also came at a high price and with increased complexity, both unwelcoming additions for any car company wanting to mainstream diesel’s.

The company has been facing several challenges recently which include the production of automotive machinery that have transmission problems whose impact has been proved to be a big problem. Pollution of the environment is another great challenge facing the company which comes both from the production mechanisms applied by the company and transmission problems of the vehicles which are released into the atmosphere greenhouse gasses. This fact places the company in a state that does not meet all the requirements of environmental sustainability. The project mainly aims at conducting an assessment of the corporation manufacturing techniques and all the necessary improvements needed to significantly reduce the levels of pollution. Implementation of innovative techniques of production, recycling of materials in production and designing cars together with machines

The automobile industry is constantly being revolutionized through new technology resulting in a fuel concept for consumer vehicles. Although these new alternative fuels are a break-through for the automobile industry, where do they stand in comparison to our conventional vehicles? This paper will address this issue by asking: What are the environmental and economic benefits and disadvantages of alternative-fueled cars compared to conventional cars?

Hence, there is always an opportunity to adopt new technology and implement them to enhance customer experience. Besides, the use of technology is more of a boon than a bane in aircrafts as it helps to lower fuel consumption and improve efficiency while keeping the cost of airline operations low.

Cars have been around for many years. The first car to move off its own power was in 1769, and 1989 the average weight of a car was about 3,000 pounds. Overtime, cars have been through many changes and improvements. Car makers are constantly in search of improving cars to be better than the last. Can lighter cars be safer? Can the fuel economy benefit if the production of lighter cars were to increase? And lastly, what are alternative composites car makers can invest in? Making cars lighter will not only make them safer, but they will also greatly benefit the fuel economy. Even though we may have the technology to build lighter and safer cars, the cost affects puts this change on hold. Changing a cars build will increase the price on cars

Abstract- Today’s environmental situation is continuing to spiral downwards; the ozone layer is receding, habitats being destroyed, and the air is being polluted. Scientists of every nation are researching ways to solve this problem. Due to automobiles sizeable contribution to the environmental crisis, studies are focusing on ways to reduce the harmful emissions caused by the internal combustion engines. Hybrid vehicles offer an alternative to powerful gas engines by providing the car with a secondary propulsion source powered by a strong battery. With this secondary power, car manufactures can reduce the size of the internal combustion engine, which accordingly reduces emissions and raises the vehicles miles

For a few decades, pollution has become an emergent hazard to the Earth. To solve that problem, human have been putting a great effort into filtering atmosphere, cleaning wastes from industrial factories, and making things greener. Waste from transportation is one of the most serious effects on environmental problems. It appears that scientists are searching for alternative fuels and evolutions in automotive industry, which must satisfy energy requirements and offer, at least, same performance compared to conventional car. The automotive industry, therefore, has turned to a new project, which is called hybrid transportation. This proposal presents how hybrid cars have developed and how that technology works in order to protect environment and save expenditure on fuel economy. Also, this will consider positive side of hybrid vehicle technology and its integration into society.

The need for reduction in weight of heavy vehicles is increasing day after day. Reduction of weight results in reduced fuel consumption which results in a
