“Aerodynamics is not a black art revealed only to a chosen few by some great god of flight. It can be understood by almost anyone, if properly explained. It can become interesting or even downright fascinating.” (Smith, 1992, p. xiii) Not only can aerodynamics become interesting, it can become and incredibly useful tool for making decisions. Aerodynamics can get complicated and involved, but so can mathematics. I have never heard somebody refuse to learn addition and subtraction simply because advanced differential calculus was too complicated. Likewise, the minutia of aerodynamics do not need to be understood in order for the science to be a useful tool. The four forces of flight, based on laws discovered by scientists, are perhaps the most basic building blocks of aerodynamics in aviation. (Kershner, 2003) Understanding these principles and how they interact with each other can help those in the aviation field make decisions and perform their jobs.
Basic Aerodynamics of Flight
The study of aerodynamics is about how air moves and the forces it creates on an object as it moves through the air. (Willits, 2007) Understanding the aerodynamic forces at work on any object can help to explain the actions of the object. The entire airplane is an object acted on by the air, therefore aerodynamics is critical. Airplanes fly because of their ability to use aerodynamics to their advantage. It is these forces that enable an airplane it to leave the ground and sustain flight. The basics of flight can be explained with the four forces acting on an airplane: lift, weight, thrust, and drag.
The four forces interact with each other and contribute the stability, maneuverability, and controllability of an aircraft. Lift is produced by the dynamic...

...ho understands the relationship between lift and drag will potentially be in a better position to help an aircraft in an emergency situation.
Conclusion
Almost every decision involving an aircraft is either going to be affected by the four forces of flight, or alter those forces in some manner. These forces are governed by laws of nature, but can be manipulated to create conditions beneficial to a particular mission. Understanding these forces will enable the managers, laborers, pilots, and crew to make the necessary decisions to get the performance needed from their aircraft. This understanding does not always happen, and is often passed down erroneously from generation to generation. (Smith, 1992) A basic accurate knowledge of how an airplane interacts with the air around it will empower those who have it to make well informed decisions as aviation professionals.
In today’s world, the use of airplanes in wars or in everyday life has become a part of how we live as human beings. Removing the air forces of the world is like taking a step back in time when wars were only fought on land or sea. WWI began only eleven short years after the Wright brothers achieved powered flight in 19031 and yet aircrafts were being used for surveillance and eventually combat purposes. It is understood that these aircrafts were primitive, but they laid down the foundation for what we know today as fighter jets. The Fokker Eindecker “revolutionized air combat by successfully employing a synchronized forward -firing machine gun mounted on the engine cowling”2. Because this airplane became the first to successfully use a synchronized machine gun, it allowed its pilots to become the first aerial combat tactitions3.

What would the world be like without flight? Today we take aircraft for granted but for centuries man could only dream of flight. It was not until the late nineteenth century that human flight started to become a reality. During this time people started to see flight as a possibility, and enthusiastic inventors began working on and experimenting with many different types of flying machines. Although there were many determined people trying to develop an airplane, the Wrights were the first because of their good methods of testing, and their focus on understanding and developing lift and control.
Leonardo provided innovative thought in the study of flight. He focused on aviation for over 23 years. Credited for using the scientific method for the first time to study flight, he observed how birds fly and then applied that knowledge to try to achieve human flight (Cooper 53). Leonardo devoted much energy into making a flying machine utilizing manually powered wings attached to a person (Kallen 55-57). Over the years, he added more and more devices to help control the plane, such as landing gear, wing slots, and a tail for steering (Cooper 53). However, he never got the flying machine to work because it weighed too much and humans could not provide enough power (53). He also made sketches for an “aerial screw” that were the basis for the design of the modern day helicopter (Hart 328). Leonardo derived the sketches from a Chinese toy that whirled rapidly (Byrd 28). The lack of a powerful enough engine to rotat...
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.
The future of the aerospace industry will involve gradual changes in the near term, with the prospect of more radical shifts in the decades t...
Now To talk about the forces that allow the car to move. There are two main aerodynamic forces acting on any object moving through the air. Lift is a force that acts 90° to the direction of travel of an object. Usually we think of lift when we think of an airplane. The plane travels forward (horizontally), and lift acts 90° to that motion of travel –
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.
Airplanes and helicopters have been significant ways of transporting goods as well as people since the beginning of the 19th century. The uses of these two machines have impacted human life more than we know it. An airplane, by definition, is a powered flying vehicle with fixed wings and a weight greater than that of the air it displaces. Contrary to the airplane, a helicopter, by definition, is a type of aircraft that derives both lift and propulsion from one or more sets of horizontally revolving overhead rotors. Both machines are incredible works of engineering and are very beneficial for separate reasons. By contrasting airplanes and helicopters, it is easy to see the structure, the purposes, and the control functions
...e in any one of these forces leads to a change in the others” (139). A pilot can use many different controls and means of propulsion to change and manipulate the balance of these forces. By doing this the pilot is able to change their speed and change their direction. The Physics of Flight are truly unbelievable occurrences that create amazing effects. Without the concept of flight we would live in a totally different world.
Aviation industry deals with more than thousands of people and also spending millions of funds in order to meet the requirements, satisfy the necessities of people and to produce state-of-the-art aircraft. With its objective it is significant to consider the hazards involved and bring out an output with the least extent and under control risks to prevent any loss in terms of life and even profit.
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.
Lift is generated by the air flow around the plane's wing. This effect is explained mostly by Bernoulli's Principle which states that the pressure of the air decreases as the velocity of the air increases. The design of a plane's wing changes the airflow around the wing's surface. The air has farther to travel over the top of the wing than the air traveling below the wing. Therefore, the air traveling above the wing is traveling at a higher velocity than the air traveling below it. As air flows around the wing, a high pressure region with low air velocity is created below the wing, and a low pressure region with high air velocity is created above the wing. The difference between the two pressures generates the lift force. (JEPPESEN 1-11)
In order to further decrease the number of airplane accidents stricter measures of evaluating an aircrafts operability prior to take off need to be implemented. Additionally, better training of pilots can also lead to a more preferable outcome should a problem arise as the pilot will be better equipped to handle an emergency.
This evaluation has not only allowed me explore calculus more in depth, but also physics, and the way the world works. This has personally allowed me to explore the connections between math and real-world situations, which is hard to find in textbooks.
