Airfoil

turn. The airframe, which was made of ninety-three percent titanium, supported the strength of stainless steel, a proportionately light weight, and was durable at the excessive temperatures, which represented that the aircraft’s leading edges of the airfoil were greater than 1,000 degrees Fahrenheit (“Creating the Blackbird”, 2014). Another design that was built upon was the F-117 Nighthawk. It was composed entirely of aluminum, with its external surfaces enveloped with radar-absorbent material…

ever produced. In other words, companies involved in these programs absorbed the innovations from these projects and used them in the next generation of aircrafts. General Electric adopted the carbon fiber composite fan blade and advanced blade airfoil design from the prop-fan, and made the most powerful jet engine to date, the GE-90. Two such engines could power a passenger jet that used to require four, with superior efficiency…

“Stop wasting your time!” my father shouted at me. “This is the most useless thing you could be doing!” “Your room is a mess again!” my mother nagged, looking at the floor. It was littered with dozens of paper airplanes, paper scraps glued to the floor, and bits of tape. “Stop making those paper airplanes!” I’ve been an engineer since I was in first grade. My favorite hobby was folding paper airplanes with a friend and having daily competitions to see who could make the plane that flew the…

way air moves around things. Aerodynamic design can either speed up or slow down the speed of air moving around an object. Thrust: the force that moves an aircraft through the air. Thrust is used to overcome drag and is often generated by engines. Airfoil: the shape of a wing that helps generate lift. Do you know The Amazonian Princess? She has a rockin’ red and blue costume. She blocks bullets with her indestructible bracelets. She holds The Lasso of Truth. She was introduced in 1941 in All…

In 1997, JK Rowling published the first installment of the Harry Potter books, a series which would come to define a generation. From apparition to house elves, every detail about this wizarding world enthralls a reader, completely transporting them into the story, to live the excellent plot alongside beautifully written characters. Due to the success of the book series, Harry Potter’s world has been under examination across multiple academic fields, from literary experts to scientific…

Getting from place to place can be a life and death prospect. Transportation in the modern era has so transformed our lives, to the extent that we take for granted how it can also save our lives. In the developed world, we simply dial 911 and emergency services arrive quickly, sometimes in minutes. But consider what technologies that timeliness requires; roads, vehicles, and/or aircraft. Unfortunately for many, such equipment is too expensive and will remain so for the foreseeable future. But…

On September 1, 1939 less than one year after the Muenchen Concord , Adolf Adolf Hitler invaded Poland. His goal was to eliminate all of the Jews. United Kingdom and Jacques Anatole Francois Thibault promised to help Poland but United Kingdom of Great Britain and Northern Ireland was too far away for their Melodic line Strength to help and France was too afraid to help because they were afraid of the Germans. Poland had very little Navy and Air Force to conflict the Germans. Poland was also…

Fluid dynamics relating to bluff bodies, non-streamlined structures or streamlined bodies at large angles of attack, remains a critical focus of study within the fluid mechanics community. One particular area of interests involves the occurrence of fluid-induced vibrations, or more commonly known as vortex-induced vibrations (VIV’s), exerted on bluff bodies. Due to the production of vortex shedding beyond bluff cross sections, an alternating pressure distribution produces periodic fluctuations…

2 Loads and Structural Stress Because of the energy content of the wind is relative to the cube of the wind speed, turbine blades exposed to wind speeds will be under an enormous amount of stress. In order to diminish the impact of wind speeds, turbine manufacturers develop the rotors on them with few blades somehow they are as narrow and long as practical (Pinting ZHANG and Shuhong HUANG 2011). The maximum efficiency from such blades can be attained based on the pitch at an optimum angle…

It is a form of the aircraft tail, composed of left and right airfoils, fixed in the tail of the fuselage, with a large anti-angle on the flat tail. Then here comes the question, why do we call such tails as butterfly ones? The reason is quite simple. If we see the aircraft from the rear point.it is just in the shape…
