Amogh Gokhale 3-21-14 Period 7-8 Fuel Efficiency in Airplanes Introduction By air or sea, planes are the most common choice of travel. This is because of how fast and efficient they are. Even though they are efficient, they still have minor downsides, including the cost. Although planes are the fastest way to travel, they are very costly. Planes can be more fuel efficient by changing their shape or type of fuel. How Planes Work The engine works by sucking on the outside air using fan. The fan then goes through a series of turbines that alternate between high pressure and low pressure. Only 85% of the air goes through this series of turbines. The other 15% goes through a pressurizer that surrounds the turbines. That air is superheated and is used as extra propulsion. The wings work because they are curved. They must be curved more on the top then the bottom. This provides lift. The more curved your wings are, the more speed is needed for lift. This requires more fuel. This, in turn, causes the flights and fuel to cost more. This can be reduced by a(making the planes wings less cur...
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.
This requires the engine to have a state-of-the-art coolant system. Big tunnels through the perimeter of the engine allows coolant to flow all around the motor at all times and keep the engine cool. The radiator is also much thicker from the factory, and is angled at 45 degrees in the engine bay to maximize air flow. The number one reason why these engines stop functioning is due to a problem with the coolant system.
The Physics Behind the Power of an Engine Insert the key, turn, and vroom. And down the road you go. Most people take for granted the strange conglomeration of metal and plastic under that sheet of metal, either in front or back of their vehicle. The engine, as you may have guessed, is a modern marvel- so to speak. They’re found in cars, trucks, boats, airplanes.
The airplane has been modified from the balloons used in the Civil War to have a powerful role in combat. During the Civil War battles were fought on the ground and people rarely took to the air. Most aircraft of the late nineteenth century were made of mechanical wings or lighter than air. Observers used balloons on the battlefield to report the status of advancing troops. Gliders were used for observations but were limited to where they could be used. During the late 1890s the American war department placed more of a focus on developing a heavier than air flying machine. In 1903 Orville Wright in North Carolina made the first fight of the modern aircraft which resulted in more research in the development of the airplane.
Higher altitudes—the higher aircraft flies, leaner the air and the greater the angle of attack is necessary for producing the lift needed to preserve the flight level.
First of all you will have to understand the principles of flight. An airplane flies because air moving over and under its surfaces, particularly its wings, travels at different velocities, producing a difference in air pressure, low above the wing and high below it. The low pressure exerts a pulling influence, and the high pressure a pushing influence. The lifting force, usually called lift, depends on the shape, area, and tilt of the wing, and on the speed of the aircraft. The shape of the wing causes the air streaming above and below the wing to travel at different velocities. The greater distance over which the air must travel above the curved upper surface forces that air to move faster to keep pace with the air moving along the flat lower surface. According to Bernoulli’s principle, it is this difference in air velocity that produces the difference in air pressure.
This hot gas is pushed out through the back and it makes the rocket move forward. This is using Newton's third law of
Wilbur Wright once said, “The desire to fly is an idea handed down to us by our ancestors who... looked enviously on the birds soaring freely through space... on the infinite highway of the air.” He changed American culture forever when he made the first flight alongside his brother Orville. This invention would have an even greater impact on our culture than cars. Although cars are used every day in America, planes have had the largest impact on American culture. Without planes, our lives would be drastically different, but not in a good way. Airplanes had a major impact on military, commerce, and travel.
All flight is the result of forces acting upon the wings of an airplane that allow it to counteract gravity. Contrary to popular belief, the Bernoulli principle is not responsible for most of the lift generated by an airplanes wings. Rather, the lift is created by air being deflected off the wings and transferring an upward force to those wings.
At one point—when cars remained extremely popular—airplane was faster yet more expensive form of travel. Yet when the United States becomes an automobile-less society this would no longer be the case. No longer could one drive an hour down the road to visit family by impulse, it would require planning for tickets and other fees. However, since plane is one of the only traveling opportunities prices surely would decrease from their once inflated
Wings create lift for the upward force of an airplane. A great example of how this happens is sticking your hand out of a car window driving down the freeway. The force on your flat palm causes a force that can lift your hand up or down by changing the
Firstly, the gas turbine engine operation begins with the air intake process. As of all internal combustion engine, oxygen is required to support the combustion of the fuel and the source of oxygen is from the fresh air that is taken in. Initially, the fan is rotated by a driving shaft that is powered by the turbine of the engine. A negative or vacuum pressure at the intake side is then created by the rotating fan. Next, the surrounding air is drawn towards the inlet and causes it to flow into the gas turbine engine inlet (Cengel & Boles, 2011). At the same time, the pressure on the other side of the fan is increased as it is compressed at a lower pressure ratio and causes the air in the outlet side of the fan to move fu...
... turned by pistons, it is fueled by a combustion process using turbine exhaust to spin the prop rather, hence the term turboprop. A turbofan is what you will find on all private business jets and airliners. Instead of turning a prop, turbofan engines use the exhaust to turn a fan which helps produce more thrust by helping creating bypass air. Military planes such as the F-22 Raptor use the plain jet engine which produces thrust by in simple terms lighting jet fuel on fire and pushing it out the back. Whatever type of engine it may be, they are all important pieces of a plane.
This along with the lighter construction of a two-stroke makes it the preferred motor used in small vehicles and tools (Two Stroke Engine). A two-stroke engine is operated by first drawing the mixture of fuel and air into the chamber by the vacuum caused by the upward stroke of the piston. During the downward piston stroke, the poppet valve is forced closed due to the increased pressure within the chamber. The mixture is compressed in the chamber throughout the stroke. As the stroke ends, the intake port is exposed allowing the mixture to escape into the main cylinder, expelling the exhaust gasses in the process and some of the fuel mixture as well. Momentum then causes the piston to rise, compressing the mixture as another stroke is beginning. Once the stroke reaches its peak, the spark plug will ignite the mixture causing the fuel to expand driving the piston down thus completing the cycle while additionally initiating a new
Land transportation is the dominant form of transportation in the world. People can move about land under their own power, either by walking or by other forms of human-powered transportation such as the bicycle. People also use domestic animals as a means of transportation, both for riding and for pulling wheeled wagons or carts.
