Aviation Fuel Efficiency on 737 Max

One of the businesses with the highest levels of competition worldwide is aviation. Airlines are always seeking methods to increase revenue while still operating effectively. To do this, there are strategies to follow; one approach is to increase fuel effectiveness. In the aviation sector, there is a discussion about purchasing electric or modifying existing engines to achieve greater fuel economy. Reviewing the studies on fuel efficiency and airline earnings before choosing is crucial. To decide if it is more advantageous to invest in electric engines or improve current engines to enhance fuel economy, this literature review will assess the studies on fuel efficiency and airline earnings. The Boeing 737 Max will be the subject of the study since it is one of the aircraft that potentially consumes less fuel while maintaining its current efficiency level. The literature evaluation will include studies on the connection between engine adjustments and fuel efficiency, aviation sector technology advancements, and the environmental impacts of each choice. This literature study will provide an informed perspective on the advantages and disadvantages of investing in electric engines or modifying present engines to increase their fuel economy by reviewing this research.

In today’s world, the aviation industry has seen a rampant increase in customers making flights. The higher demand has triggered the use of planes with less fuel consumption. In the past few years, airlines have tried to find ways to use fuel more efficiently to cut costs and make more profit. Boeing 737 Max is one of the planes that could use less fuel while still being as efficient as it is now. Investing in electric cars could be one way to fix the problem of falling gas mileage. Electric engines could cut the airlines’ expenditure on fuel; this is because electric engines work better than regular ones (Birch, 2000). Electric engines are expensive, so some airlines have more cost-effective options.

Buying new electric engines for Boeing 737 Max may be expensive; therefore, it is prudent to use cost-effective methods to be cost-effective. One of the best methods is altering the features of the engines already in the Boeing 737 Max to make them use less fuel. Altering these engines involves making the vehicle more aerodynamic, managing the fuel, or making the engine’s architecture more efficient (Janssen & Emmelmann, 1978). Because of these upgrades, the planes may use less fuel, which could mean the airline’s operating costs will decrease. Also, these changes can be made by spending less money than acquiring new electric engines.

To make an informed decision on whether it would be better to invest in electric engines or make changes to the engines already in use to get better fuel efficiency, it is crucial to look at the research on fuel efficiency and airline profits. The research will make it easy to compare the possible benefits of each choice. According to Lu et al. (2021), the relationship between engine changes and fuel economy engine changes could lead to a 10% improvement in the vehicle’s overall fuel efficiency. Further, another study found that upgrading the engine can save up to 15% on gasoline costs. (Donateo & Spedicato, 2017). Therefore, these results suggest that improving engines by making necessary changes is the best way to improve fuel economy and reduce fuel costs.

Capoccitti et al. (2010) said that using electric engines affected fuel economy. The research found that using electric engines could improve fuel economy by up to 20%. Further, the research found that the fuel cost for electric engines might decrease by as much as 25%. Therefore, according to these results, electric engines could be an excellent way to improve fuel economy and lower the cost of fuel. But since electric engines require intense capital, it may be inappropriate for some airlines as they may need help to afford them.

To better understand the pros and cons of investing in electric engines or making changes to the engines we already have to make them more fuel efficient, it is important to look at the research on technological advances in the aviation industry. This study is significant since it assists individuals in determining what the best course of action is (Taylor & Coy, 2000). This will also assist you in determining the benefits and drawbacks of the various options. The aviation industry has swiftly embraced several innovative technologies in recent years. Most of these technologies are concerned with effectively employing aerodynamics and developing engines (Taylor & Coy, 2000). Due to these technological advancements, aircraft can utilize gasoline considerably more effectively, lowering airline fuel costs. Moreover, these technologies are cost-effective since they may be utilized to produce changes that do not cost as much as purchasing electric engines, which are expensive.

While comparing the benefits and drawbacks of investing in electric engines or adjusting current engines to make them more fuel efficient, it is essential to consider both the positive and negative impacts each option may have on the environment. It is critical to consider the environmental consequences of each option, both good and harmful. People may use less fuel and produce less pollution using electric engines and improved internal combustion engines, which is excellent for the environment (Lee & Mo, 2011). Improved fuel economy may also help airlines generate more money, which they can put into greater research and development on fuel-efficient aircraft. This might make it simpler to enhance fuel-efficient devices in the future, resulting in less pollution and reduced gas costs.

Furthermore, it is critical to consider how these expenses may influence the aviation sector as a whole. Better fuel economy might significantly decrease fuel costs, making airplanes more lucrative (Singh et al., 2019). More money spent on research and development of new technologies may result in outstanding technical advancements and a more competitive aviation sector. Improved fuel economy may also encourage more passengers to travel, resulting in more significant airline revenue.

In conclusion, the analysis focused on the Boeing 737 Max airplane. It weighed the potential advantages and disadvantages of purchasing electric engines vs. changing the current engines to improve their fuel economy. The Boeing 737 Max airplane has been the subject of this analysis. According to the study that was looked at, both electric engines and modifications to current engines have the potential to lead to better fuel efficiency and lower fuel costs. Moreover, technological advancements in the aviation sector may enhance fuel efficiency, lowering fuel costs. Also, improving fuel efficiency can boost airline profits, which can be reinvested in more research and development of technology that improves fuel efficiency. Last but not least, improved fuel economy has the potential to significantly reduce fuel costs, which might lead to enhanced airline profitability, more investment in R&D, and more competition in the aviation sector. The results of this evaluation generally point to the need for additional research into the effects of investing in electric engines rather than improving current engines to increase fuel economy fuel efficiency, and airline profitability.
