Aerodynamics
Question 1
The continuity equation deals with the law of conservation of mass. The law of conservation of mass is illustrated by the continuity equation based on two aspects. Firstly, the air flow may either be steady or unsteady.
For the unsteady flow,
The second aspect of the equation deals with a steady flow and it’s illustrated as
Applying this is an aircraft’s engine an aircraft requires the correct amount of airflow in order to increase its thrust in flight. Since at cruise speed an engine thrust accounts for only 17 %, there is need for the aircraft to take in more air in order to increase the thrust. The continuity equation is therefore an important contribution to the airflow into and out of the engine. The pressure has thus to be balanced at the compressor in order to allow for increased intake at the intake. This would then be as stipulated by the continuity equation which illustrate that the mass flow rate of change at the intake minus the mass flow rate at the outlet will give the rate of change of mass storage. This storage mass is what influence the increased thrust.
There is also a very large contribution of the airflow intake to the pressure ratio of the plane. This means that since the engine’s effect to the pressure is negligible, it’s the air flow which affects the pressure ratio. For this reason, the amount of air being sucked in by the plane determines the pressure ration as well as the thrust. There is therefore a need for increased air intake in order to influence the rate of change of storage.
In order for the aircraft to experience more air intake, several parameters have to be altered. This is because the air intake into an aircraft is influenced by flow distortion, turbulence ...

...principles that are related to the gas laws and the thermodynamic principles. For this reason, these aspects are very important since they illustrate the various changes in pressure, volume, and temperature. A change in any of the three elements cause significant change to the others as well as in the energy generated during the entire time. The thermodynamic principles help in the explanation of the energy differences as well as entropy generated from the initial internal energy in systems.

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.

Pressure is a main factor in turbo chargers. Pressure is the force exerted on a surface divided by the area of the surface (force per unit area). Decreasing the volume increases the pressure. The average speed of the molecules do not change. If we increase the number of particles in a same volume, we expect the pressure to increase because there would be more frequent collisions between the particles and the walls of the space. Temperature is also very important. If the temperature of the gas increases, the speeds of the particles also increase. Pressure and volume are inversely proportional, (by Boyle’s Law) as one increases, the other must decrease. Gases want to flow from a high pressure area to a low pressure area. The greater the difference, the faster they flow. I...

In the project for science fair, we will be dropping whirligigs to test, which have the most aerodynamic structure. We will be recording the weight of the paper clips we put onto the whirligig. We will use the app that tracts how the whirligig falls. Which is called “Vernier Video Physics”. Then when we have enough data we will try to make the perfect paper airplane. To get the perfect paper airplane we must have the correct weight, the correct thrust, and the correct aerodynamics of the whirligig, this is why our project mostly consists of aerodynamics.

Aviation has come a long way since the 19th century, from the Wright brothers taking flight with the first powered and controlled gliders, to aircraft that can travel up to supersonic speeds, orbiting satellites and space stations which then were only thought to be science-fiction. Aerospace and aviation has proven to be one of the biggest challenges to advance in the entirety of human existence. There are many factors and characteristics that contributed to this advancement such as the engines of aircraft, forces of flight, aerodynamic forces, wingspans etc. The two most significant aspects however have been; World War 1 and World War 2.

Flight uses four forces: lift, weight, thrust, and drag. In a nutshell; so to speak, an airplane must create enough lift to support its own weight. Secondly, the airplane must produce thrust to propel itself. Finally, the aircraft must overcome the drag or the force of resistance on the airplane that is moving through the air. All four of these forces are vital and necessary for an aircraft to move, takeoff, fly, and land.
The basic concepts of lift for an airplane is seen. The air that is flowing splits to move around a wing. The air that that moves over the wing speeds up creating lower pressure which means that the higher pressure from the air moving slower under the wing pushes up trying to equalize the pressure. The lift generated can be affected by the angle at which the wing is moving into the flowing air. The more surface area of the wing resisting against the flow of air can either generate lift or make the plane dive. This can be easily simulated in everday life. Next time you are riding in a car with someone stick your hand out the window. Have your fingers pointing in the direction of the motion of the vehicle. Now move your hand up and down slightly. You can feel the lift and drag that your hand creates.
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...
so they could compress the air at a much higher pressure so the engine can
The future of passenger aircraft and their manufacture has an amazing outlook. Every year, the brightest minds in aviation compile the greatest technological advances towards creating the safest and most economical aircraft on the planet. No detail is over looked, and the bottom dollar is the controlling factor. From private aircraft to public aircraft, space exploration and beyond, the future is bright for the passenger aircraft market, and everyone who purchases air travel should be excited to see how the industry unfolds. Let's kick this off!
The humble aeroplane commonly known as the airplane or just plane has become a staple of everyday life for the majority of us. Aeroplanes are used for a vast variety of reasons, the most common being transporting people long distances in a very short amount of time. However, this is not the only role that they play in society, they are used for many other things such as; transportation of goods, recreation, military and research. Aeroplanes are a fixed-wing aircraft that is propelled forward by thrust, usually from a jet engine or propeller. This essay will discuss the history of how this technology that we know and love came to fruition and how it reached the market through diffusion.
