Introduction
This assignment talks about the Atmosphere and then how the air flows throw the airfoil and what are its effects. It also covers the Bernoulli and venturi principles with relation to the generation of lift and many other related questions like drags and basic forces that act on an aircraft. It all comes under the heading Theory of Flights.
Task 1 (LO1, P1)
1) What do you understand by the term International standard atmosphere (ISA)? Why is it so important in the field of aviation?
2) Define the standard sea level values for pressure temperature and density and also produce a graph to show how they change with altitude.
1) The atmosphere is never the same at any place or time. Hence the international Standard Atmosphere (ISA) was invented as a model that describes the pressure, temperature, density and viscosity of the earth's atmosphere with respect to change in altitude. [1]
Inspecting an aircraft's performance which is in air is a prime duty of an aircraft engineer along which he should also be aware of all these following values:
• Temperature
• Pressure
• Density
• Local speed
2) The standard sea level values for pressure, temperature and density is

Task 2 (LO1, P2)
1) Explain what to do you understand by laminar and turbulent airflow over an airfoil.
2) Explain what dynamic and kinematic viscosity is. How are they important in the field of aviation?
1) Laminar Flow: Laminar flow flows in a streamline over an airfoil without the disturbance or inference of any air particle as there is an equal and parallel distance between those air...

Flying alongside the clouds at high altitudes; to hear nothing except the thoughts in my head and to go to far away destinations on a weekend is just some of the reasons I enjoy flying. I start out early in the morning heading out to the local airport. At that time in the morning, I can feel the chill in the air. It is so quiet at the beginning of dawn. I know when I am close to the airport; I can smell the aviation fuel burning from the aircraft on the runway. Once I arrive, I head straight to the aircraft hangar where I left my aircraft the previous day. Next, I would walk around the aircraft to do a visual inspection of any damage to the aircraft that may have been done on a previous flight. If there is some minor damage, I log it in my flight log. Once I am done with the preliminary outside inspections, I move inside the flight cabin where I set the instruments for the day’s flight. Once the instruments are set, I crack my window slightly and yell, “CLEAR.” I turn the key to the right; the propeller starts to turn with a clank, clank sound; suddenly the engine comes to life. WOW, what a feeling that is to hear the engine comes to life. I place my headset on my head and say, “Clermont, WNS77 with radio check, Clermont.” The tower replies with, “Clermont, WNS77 radio check, load and clear, Clermont.” The thrill of flying has always had a place in my heart and being a part of the Experimental Aviation Association, also known as EAA, has help me feel closer to my desires of flying with the heavenly bodies. The main goal of the Experimental Aircraft Association is to bring individuals, like myself, together and share in the joy of all parts of aviation. This can include homebuilt aircraft, exploring new technology in the field of...

Introduction to Aerodynamics Aerodynamics is the study of the motion of fluids in the gas state and bodies in motion relative to the fluid/air. In other words, the study of aerodynamics is the study of fluid dynamics specifically relating to air or the gas state of matter. When an object travels through fluid/air there are two types of flow characteristics that happen, laminar and turbulent. Laminar flow is a smooth, steady flow over a smooth surface and it has little disturbance. Intuition would lead to the belief that this type of air flow would be desirable.
For a plane to create lift, its wings must create low pressure on top and high pressure on the bottom. However, at the tips of the wings, the high pressure pushes and the low pressure pulls air onto the top of the wing, reducing lift and creating a current flowing to the top. This current remains even after the wing has left the area, producing really awesome vortices.
Ever wonder what the atmosphere consists of? What's it made out of, what type of weather patterns are there, what does a hurricane look like, or other natural phenomenon's of today's weather ? Well America, hopefully now we can! Meteorology is the study of the atmosphere and the effects it has on our weather. Climatology focuses on how atmospheric changes alter the world’s climates, aeronomy is the study of the upper parts of the atmosphere. Meteorology focuses on the lower parts of the atmosphere, primarily the troposphere, where most weather takes place. It has been released that under the supervision of NASA, President Dwight D Eisenhower and the National Oceanic and Atmospheric Association (NOAA) that they have launched a satellite called TIROS 1 out of Cape Canaveral, Florida that will observe, record, and transmit data back to headquarters. The first ever weather satellite has arrived and with much hope will change weather prediction for the future.
To investigate the relationship between the air pressure in a ball and the bounce height of that ball where the drop height (gravitational potential energy), temperature and location are kept constant.
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.
This paper will explain a few of the key concepts behind the physics of skydiving. First we will explore why a skydiver accelerates after he leaps out of the plane before his jump, second we will try and explain the drag forces effecting the skydiver, and lastly we will attempt to explain how terminal velocity works.
According to Brian Dunbar, NASA Administrator, "Aerodynamics is the way air moves around things." Furthermore, it is a branch of fluid dynamics that is concerned with the study of forces and gas flow and based on the concept of Newtonian Mechanics. Whatsoever moves through air reacts to aerodynamics. A rocket launching and a kite in the sky both react to aerodynamics. According to Avaiationbox, "The solution of an aerodynamic problem normally involves calculating for various properties of the flow such as velocity, pressure, density and temperature, as a function of space and time." In addition, it states that the aerodynamics have two classification criteria where study of flow around solid objects is one and the study of flow through passages in solid objects is another. The major goal of aerodynamics is also to anticipate the aerodynamic forces on an aircraft.
- the effect of Viscosity on liquid flow (turbulent/laminar) I have consulted my teachers for guidance and I have also looked very carefully into the "the Suggestions papers" which contain many possible investigations which have been done in the past. I opted to choose neither of them but many aspects I will be looking into in my investigation are similar to those in the papers.
Viscosity is the resistance to flow of one layer of the liquid over the other. It is the measure of the thickness of a liquid.
