Introduction In the quest to build an electric powered aircraft the engineers of all times have faced obstacles when they have to design and build these aircraft, one of them is the size and weight of the batteries that run the electric motors, the weight has been too heavy and not producing enough energy to supply the needed power. Other of the main obstacles is that the consequences of failure were too high and if these aircraft running out of power meant a guarantee crash landing. During the last several years and encouraged by the progress in technology and the batteries becoming lighter, more powerful and efficient that the interests in electric propulsion systems for aircraft has grown considerably. While not quiet yet to build full size electric powered aircraft but we are seeing the developing and manufacturing of various hybrid aircraft and smaller size all electric powered aircraft. Industry Incentives As the hybrid designed aircraft makes a such a great improvement in efficiency due to the use of a relatively small fuel driven engine designed to run at its most efficient during cruising altitudes and use only the battery and electric motor to provide the extra power needed for takeoff and climbing, in addition the battery can recover the energy from the small fuel driven engine during descent when the propellers spin a generator to produce electric power to charge the batteries. The recent grown in motivation for the study and developing of alternative propulsion systems is in great part of the clearly growth of the air transportation industry and this only means more fuel burning and a higher impact of the aviation industry on the environment and it will take many years until current aircraft are replaced with new gene... ... middle of paper ... ... Conclusion In my opinion I don’t see the implementation of electric or hybrid powered commercial aviation anytime in the near future because that turbo fan engine technology is still advancing at a fairly rapid pace and with the new technology these engines will significantly improve efficiency within the next few years and many more engine manufactures will add further improvement in the next couple of years outpacing electric and hybrid powered propulsion system improvements for the near future.

    Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.

  • New Technology of General Electric Jet Engines

    How many times a day do you hear a jet airplane roar over the top of your house, leaving a trail of dark, black smoke behind? People all around the world are complaining about the noise and contamination that jet aircraft produce as they fly over densely populated cities. Airplanes are flying around the clock consuming thousands and thousands of gallons of fuel a minute. So many jet engine manufactures have tried time and time again to reduce the noise and contamination that their engines produce yet so many times to no avail. General Electric is now incorporating new technology into their engines that will reduce not only the fuel consumption and contamination produced by the jet engines, but increase their thrust output.

    These cars operate from a rechargeable battery and gasoline. The engines are smaller so that they will be able to accommodate the 99% of time when the car is not going uphill or accelerating quickly. The battery is used to give extra acceleration power if needed. When the car is stopped, hybrid gasoline motors can shut off and run off their electric motor and battery. These cars are aerodynamic and the tires are often stiffer and inflated higher to reduce dragging.

    The future American commuter will undoubtedly have to transition from the use of fossil fuels to new alternatives due to the diminishing availability of the nation’s oil resources. How will America respond to this upcoming issue? It is difficult to predict which alternative fuel source America will ultimately choose, but with the premier of Nissan’s electric powered Leaf and other companies; such as Tesla Motors and Chevy, with their electric cars ready for market, the electric car may be winning the race to become the new standard for the gasoline alternative. Electric cars resolve long standing environmental issues, but it will need to maneuver around many roadblocks to become a marketable consideration for the general public. The cost of electric cars, currently on the market, makes them an impractical purchase for the average consumer. If cost is not the growing concern in today’s economy which prevents the consumer from considering this option; they may deny the technological advance due to battery storage capabilities and the inadequate infrastructure in place to refuel and provide for them.

  • The Electric Car: The Power Of Electric Cars

    1399 Words  | 3 Pages

    (Gilpin, 2014) According to Tesla, the efficiency of electric cars is three times that of the traditional gas engine as most energy is lost through the heating process.(Gilpin, 2014) There are two types of electric vehicles in production today, BEV’s and PHEV’s. BEV’s or Battery electric vehicles run solely on energy stored in a battery that is recharged at stations. These cars have an operating range of 60+ miles and take about 6-8 hours to recharge at a station.(Gilpin, 2014) Those who need to travel more than 60 miles in a day could face problems with this. Those that may need to travel much farther in a day would be wise to choose the PHEV’s or the plug-in hybrid electric vehicle. These vehicles run on both electricity and gasoline. They can run on electricity alone for up to 40 miles until it makes the switch to gasoline acting like a hybrid. This means that after they switch to their hybrid mode, they will use both electric and gasoline powered until they are charged again.(Gilpin, 2014) While in hybrid mode the PHEV’s can run up to 400+ miles before needing a recharge. (Gilpin, 2014) The relevance of electric cars is spiking. Especially in bigger cities that have air quality issues, the demand for transportation with limited emissions will be a huge

  • Avation and Its Impact on the Environmen

    725 Words  | 2 Pages

    Introduction Aviation has a huge environmental impact on the environment and society, the aircraft engines release a noise that affects human life and the particulates and gases that are released from the aircraft engines contribute to climate change and increases the global warming. Despite the emission reductions from cars and more fuel-efficient and less polluting turbofan and turboprop engines, the rapid growth of air transportation in the recent years contributes to an increase in total pollution attributable to aviation. In the European Union, greenhouse gas emissions from aviation increased by 87% between 1990 and 2006. Like any other form of public mass transportation that relies on resources that are extracted from the planet, for e.g. Oil, and the airline cannot be considered sustainable in the long-term. Because of the limited resources in which the Aviation relies, it is more realistic to think about how to improve the sustainability of the air transportation rather than achieving a sustainable development.

    To this day I still remember the first time I saw an electric car. I remember coming home to my mother and telling her that I saw a car that runs on no gas. My mom, being the classic uneducated woman looks at me and said “what movie did you get that from”, I laughed as I searched it on my phone, and showed her the different models of electric cars. Soon after my mother was telling everybody how she would love to have the new sleek, trendy modern electric car “The Tesla”. Ever since the day I laid my eyes on that car, I sincerely found my fascination with electric cars. Electric cars are truly the best cars ever created! To begin with, electrical cars don’t need gas to operate. Furthermore, Electrical cars are safer, they don’t

    There are two configurations for hybrid cars. The first configuration uses gasoline engine to run a generator. The generator supplies electricity to the motor, which drives the wheels, which allows the gasoline engine to run constantly while achieving optimum fuel efficiency. This thereby minimizes emissions owing to incomplete combustion. A hybrid car with parallel configurations uses both an engine and a motor to drive the wheels depending on driving conditions. "A hybrid car is an automotive equipped with two or more sources of motive energy" (http://www.howstuffworks.com/hybrid-car1.htm).
