Recommended: Basic aerodynamic essay

Aerodynamics is generally summarized in these 2 terms: “Lift against Weight” and “Thrust against Drag”. This basically means the amount of flight power generated must be equal to, or greater than the amount of weight of the airplane, and the amount of pushing generated, must be equal to or greater than the airs resistance. But the overall question, so far, is how is “Lift” and “Thrust” generated? The answer to how “Thrust” is generated is quite simple. Its sort of how a car would move, except in a much different way. Airplanes have 4 engines, which can each exert easily up to 200 PSI of air (pressure per square inch), composed of liquid fuel cylinders, and internal combustion (like a car). It also tops to 250 km per hour on the runway! But how “Lift” is generated is, the true definition of aerodynamics. The first thing you must consider to understand this is that the wing of the plane is specially designed, to force the air above the wing to rush faster, than the air beneath it. This works according to the “Bernoulli’s principle”. The reason air above the wing must be fast...

    The history of flying dates back as early as the fifteenth century. A Renaissance man named Leonardo da Vinci introduced a flying machine known as the ornithopter. Da Vinci proposed the idea of a machine that had bird like flying capabilities. Today no ornithopters exist due to the restrictions of humans, and that the ornithopters just aren’t practical. During the eighteenth century a philosopher named Sir George Cayley had practical ideas of modern aircraft. Cayley never really designed any workable aircraft, but had many incredible ideas such as lift, thrust, and rigid wings to provide for lift. In the late nineteenth century the progress of aircraft picks up. Several designers such as Henson and Langley, both paved the way for the early 1900’s aircraft design. Two of the most important people in history of flight were the Wright Brothers. The Wright Brothers were given the nickname the “fathers of the heavier than air flying machine” for their numerous flights at their estate in Kitty Hawk, North Carolina. Orville and Wilbur Wright created a motor-powered biplane in which they established incredible feats of the time. The Wright Brothers perfected their design of the heavier than air flying ma...

  • The Airplane's Impact in World War One

    657 Words  | 2 Pages

    World War One was known as the war that would end all wars. At first, airplanes in the war were thought to have just little combat use. An unknown British general even commented, " The airplane is useless for the purpose of war." In the beginning of the First World War, the airplanes were pretty simple and raw. By the end of the war, aircraft had become more advanced and had split off into fighters, bombers and long-range bombers. The specifications of the airplanes were changed to meet the war's requirements. When the War started in August of 1914, British airmen were associated with the British army and their commissioned officers had army ranks. Before the United State’s declaration of war in 1917, American nationals had enlisted in British and French air services including the Lafayette Escadrille. By the time the war ended in November of 1918, the Royal Flying Corps no longer prevailed and was absorbed into the recently developed Royal Air Force. The Royal Air Force now had its own command structure away from the army and provided its own ranks.

    The First World War was monumental in history because of all the new technology that was introduced. One particular area that developed during the Great War was the use of airplanes by the German and Allied militaries. In comparison, they both had different mentalities towards an invention that was only made successful less than a decade before the outbreak of war in 1914 by the Wright Brothers in North Carolina, United States. The German Military welcomed the idea with open arms, investing in its potential for military uses, whereas the Allies remained reserved and hesitant, claiming that aircraft could not be used for anything more offensive than reconnaissance missions. These differences in opinions later affected the development of each air force. The German military kept making consistent improvements to their equipment whereas the allied pilots were slow in their respective air force evolution. However, there was a common progression that both militaries had which was the slow phasing out of the cavalry on either side due to the effectiveness of the aircrafts reconnaissance and battle capabilities. During the World War One, the German military took advantage of the new technology available to them, which gave significant results, whereas the Allies had a more traditional mindset and followed behind at a slower pace.

    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.

    What is aerodynamics? The word comes from two Greek words aerios concerning the air, and dynamis, meaning powerful. Aerodynamics is the study of forces and the resulting motion of objects through the air. Humans have been interested in aerodynamics and flying for thousands of years, although flying in a heavier-than-air machine has been possible only in the last hundred years. Aerodynamics affects the motion of a large airliner, a model rocket, a beach ball thrown near the shore, or a kite flying high overhead. The curve ball thrown by big league baseball pitchers gets its curve from aerodynamics.

    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 –

  • The Physics of Flight

    The trials and tribulations of flight have had their ups and downs over the course of history. From the many who failed to the few that conquered; the thought of flight has always astonished us all. The Wright brothers were the first to sustain flight and therefore are credited with the invention of the airplane. John Allen who wrote Aerodynamics: The Science of Air in Motion says, “The Wright Brothers were the supreme example of their time of men gifted with practical skill, theoretical knowledge and insight” (6). As we all know, the airplane has had thousands of designs since then, but for the most part the physics of flight has remained the same. As you can see, the failures that occurred while trying to fly only prove that flight is truly remarkable.

    Paper Airplanes, flight at its simplest for humans. As kids, we learned how to build paper airplanes and send them soaring into the sky. We didn't stop to think about why the airplanes where able to fly after the initial thrust we gave them or how they were able to glide for so long afterwards. Ignorance was bliss then, but now we strive to understand how things work. Looking back to the childhood past time of flying paper airplanes, I will try to explain some of the parts that make paper airplanes fly.

  • Physics of a Plane Crash

    1948 Words  | 4 Pages

    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)

  • Physics of a Car

    The aerodynamic efficiency is the single most important element in designing a competitive car for professional racing or getting the car model on the front of a Car and Driver or Motortrend. Aerodynamics is the study of the motion of gases on objects and the forces created by this motion. The Bernoulli effect is one of the most important behind car design. The Bernoulli Effect states that the pressure of a fluid, in gaseous or liquid state, varies inversely with speed or velocity and a slower moving fluid will exert more pressure on and object than the same fluid moving slower (Yager). The goal of car designers is to make the air passing under a car move faster than the air passing over the car. This causes the air passing over the car to create more downforce than the air passing under the car creates upforce creating a force additional to the car’s weight pushing the car to the road. Large amounts of downforce are needed to keep light cars grounded at high speed and keep to cars from sliding around turns at high speeds.

    There are many factors to why a rubber band airplane flies like lift, gravity, thrust, stability, angle of attack, and air drag, but let me start at the beginning The Wright brothers were the first to produce a manned, heavier-than-air machine that left the ground by itself, moved forward, but didn't decrease speed, and landed on a higher point than where it started. Their airplane flew in 1903, but was only in the air for 12 seconds, as months went by they improved the flight time to 38 minutes. They never graduated high school, but developed the first flying airplane.
