The aim of this experiment is to understand the non-linear aerodynamic characteristic of a slender wing-body (rocket shaped) by installing the slender wing-body inside the wing tunnel and run the wing tunnel at subsonic speed and changing the incidence angle of the slender from -14 to 28 degrees over period of time and record the lift and induced drag readings from a computer which is connected to the wind tunnel.…
The technology behind jet aircraft power has essentially contained two major components. Those are the jet aircraft engine and its fuel. Less than a hundred years after the Wright brothers flew that faithful flight, technology has exploded in jet aircraft engines. We can now fly at altitudes and speeds the first aviators would never imagine. One can only imagine what the future holds for the technology of tomorrow. (Bilstein)…

Thrust is when you throw the paper airplane and how much force you use to throw it. Another force pushing it up is lift. Lift is “air moving over and under the wings is providing an upward lift force on the plane”. 1. Without these force the paper airplane will not go up.…
Drag is the force of flight that pushes an airplane opposite to the direction it is moving. The biggest types of drag are friction, when air rubs against the surface, and difference in air pressure. Think of a drag like swimming treading through the water you can't move as fast as you can on land the reason for that being because the water is causing drag on your body. The planes shape, size, and speed also affect the amount of drag on an aircraft. These are the factors of aerodynamics. Wings aerodynamics is shown by it's lift to drag ratio. The lift will make at a given speed an angle and can be one to two orders of magnitude greater than the total drag on the wing. High lift to drag ratio needs a smaller thrust to push the wings through the air at with a sufficient lift.…

At any given moment, roughly 5,000 airplanes crisscross the skies above the United States alone, amounting to an estimated 64 million commercial and private takeoffs every year (source: NATCA). Considering the rest of the world 's flight activity, the grand total is almost incalculable. In order to understand how airplanes fly, we must break down the parts of an airplane and understand the physics behind the airplanes most important components: the engine/propeller, and the wings.…
* A little background information on paper airplanes is important to understand why people started making them in the first place. Paper airplanes are believed to be from Ancient China and Japan. The idea came from the art of folding paper, or better known as, origami. This concept became popular around 500 BCE in China, and within the next decade the paper airplane became popular as well. The Wright brothers actually used paper airplanes before they designed actual planes. Paper airplanes have improved over the years and have gained a lot in terms of flight performance. I am going to include two examples of other students and people that have done research or experiments with paper airplanes. The first one is in a paper, “Physics of Paper Airplanes”. In this paper the science behind paper airplanes is discussed in detail. I learned that the thing that makes paper airplanes actually go longer and “flow” through the air for a certain amount of time is called, “lift.” As stated in the paper, “Lift can only happen when in the presence of a moving fluid and air has fluid properties.” (– Anonymous, 2011).The second example of airplane research and experiments…
LOOK AT A BIRD'S WING FROME THE SIDE. IT HAS A THICK FRONT EDGE AND A DOWNWARD CURVE TOWARD THE BACK. THE DISTANCE OVER THE TOP IS GREATER THAN THE DISTANCE ACROSS THE BOTTOM. WHEN A BIRD MOVES THROUGH THE SKY, THE AIR AT THE FRONT OF THE WING SEPARATE AS IT FLOWS OVER THE WING'S SURFACE. THE AIR TRAVELYNG OVER THE TOP GOES FASTER THAN IT DOES ACROSS THE BOTTOM. THAT'S BECAUSE IT MUST GO A LONGER DISTANCE IN THE IN THE SAME AMOUNT OF TIME. THE DIFFFERENCE IN AIRSPEED CAUSES A DIFFERENCE IN AIR PRESURE. THIS PULLS THE WING AT THE TOP, PUSHES IT FROME BELOW, AND CREATES A FORCE CALLED LIFT. IS WHAT KEEPS A BIRD UP IN THE AIR WHILE IT IS…
In this activity, you will witness the development of the first controlled, sustainable human-powered aircraft as chronicled in the Academy Award-winning documentary, The Flight of the Gossamer Condor.…
An equally important topic to discuss aside from the invention of the airplane itself, is the concept and importance of airplane stability that first began to appear in the 1900s. With this in mind, airplane stability refers to the tendency of an airplane remaining in a straight and upright position despite there being a change in attitude during the flight (Vincenti, p. 52). However, while the invention of the airplane was gradually gaining the interest of inventors/pilots during the late 1800s into the early 1900s, the importance of airplane stability was not always obvious and was often taken for granted. For example, in the 1910s, airplane stability was often referred to as a confusing term that was valued as important based on a matter…

JetBlue Airways Corporation got its start on February 11, 2000, and has since grown exponentially from the mere beginnings of $160 million. The company prides itself on standing out from the crown, offering leather seating, personal Televisions, and the option to choose “point-to-point” flights, just to name a few (SlideSahre.net, 2010). They have established themselves in the air world as offering a differentiated product as well as low fares. Their approach to reaching destinations is different than many other airlines, such as using the point-to-point system.…
“Forget of all the reasons it wont work and believe the one reason that it will.” Wilbur and Orville Wright were the first brothers to successfully build a modern flying airplane. The Wright Brother’s were self-taught engineers in there own bicycle shop that they had owned for quite a while. These two siblings were interested in flying planes at a young age when a gifted toy helicopter was given to the boys, which sparked their intelligence. In numerous errors and experimental fails of treacherous take offs, the Wright Brother’s expanded a new, rapid way of flying aircraft that changed the U.S aviation.…
Rolls Royce is unique for its patented manufacturing process of its hollow wide-chord titanium fan blades. To make these fan blades light and strong the fan blades are made from titanium 6-4 alloy with a hollow internal “Warren–Girder” structure. This is done using 2 processes namely Superplastic forming and Diffusion bonding.…
