Since the beginning of aviation, aircraft have been used for other intentions besides carrying passengers and cargo. They have been used as weapons of war dating all the way back to the first world war, and the use of aircraft has enlightened the advancement of the aviation. “Throughout the history of aviation, the greatest progress in flight has been made during time when either war or the threat of war was present” (Millspaugh, et al., 2008, p. 33). However, the war we face today has been triggered by the deliberate use of aircraft to cause death, destruction, and mayhem.

Newton’s laws of motion are three physical laws that describe the connection between a body and the different forces acting upon it, as well as its motion in response to those forces. Isaac Newton developed Galileo’s ideas further and developed three law of motions. Newton’s First Law of Motion states that an object at rest with remain this way unless if it affected by a force. Also if an object that is moving will continue at the same speed as well as the same direction until an unbalanced force acts upon it. An example of unbalance force is when a scooter is being driven, the friction and air resistance is going at it, the weight of the scooter is keeping the weight on the ground, the reaction force is going up and the thrust of the scooter going forward. The force’s tendency to resist any change in motion is called an object’s inertia. Newton’s Second Law of Motion states that an object will keep on accelerating in the direction of an unbalance force acting upon it. The mass of the object and the size of the force acting depends upon the size of the acceleration., F_net=m x a, is the formula to work out the total amount of force acting upon an object. This formula can be

Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.

Some common terms used in describing bush planes are stall speed, STOL, ground roll, take off distance over 50 feet, and rate of climb. Stall speed is when the airplane stops producing enough lift to fly, and the airplane stops flying. STOL is an acronym for Short Takeoff and Landing. Ground roll is how many feet it takes for a plane to takeoff. Take off distance over 50 feet is how many feet it takes for a plane to take off from being stopped to climb 50 feet in the air. Rate of climb is how many vertical feet per minute, FPM, an airplane can climb.

“The human being is set apart from all other animals by an intelligent, reasoning mind. Another quality that humans seem to possess is an inherent drive to utilize that mind to achieve to recognize challenges and to attempt conquer them” (Smith, 1992, p. 1). One of my favorite person that I used to read about in high school was Benjamin Franklin; one of the founding Father of the United States of America and the master mind behind the invention of electricity. As stated in the words of Smith, the curiosity of Franklin lead him to discover how electricity works. This same driven factor of human mind was what led the Wrights Brother to invent and fly the first power aircraft. The four forces that are acting on an aircraft in flight are: Lift, Weight, Thrust and Drag.

Lift is one of the most contested components of airplane flight. There are different theories in how an airplane reacts to air being rushed over its wings. In all actuality the entire airplane promotes lift. Often it is forgotten how the top portion of the airplane and wing plays just as an important role in creating lift as the bottom of the airplane and wing. As stated in How Airplanes Fly “Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air” (Eberhardt). Lift must overcome or be equal to the weight of the airplane (Eichenberger). Lift is produced as the air flows over the body and wings of the airplane as it is moving forward. The wings help to develop most of the lift due to their design. They come in different shapes and sizes, from short wings to very long wings, even a propeller of a helicopter is considered a wing. No matter what size or shape, wings are designed to create lift. According to Newton’s third law, for every action there is an equal and opposite reaction. This means the lift of a wing is equal to the change in momentum of the air it is diverting downward (Eberhardt). Pilots have controls to increase the size of the wing while the airplane is flying, thus increasing lift and helping to keep the airplane flying at slower speeds.

The lift force that allows a plane to remain in the air is created by the airflow passing over the wings. This airflow only occurs if the planes is moving through the air meaning that lift is only possible if a plane

The final portion of an aircraft to be created is the landing gear. Before this can be done, all of the other major pieces of the aircraft must be completed. These parts include the propulsion system, the tail, the wing, and the fuselage (Malev Virtual Training Division, 2005). Before the landing gear is designed, the stability of the aircraft must be proven, by establishing its center of gravity (Federal Aviation Administration, 2014). In a few circumstances, the structure of the aircraft my need to be changed by the designer in order to accommodate the landing gear. The main roles of the landing gear include stability of the aircraft during taxi and on the ground, loading, and unloading. The landing gear allows the aircraft to move and maneuver freely during taxing. The landing gear also separates main components of the aircraft like the fuselage and the wing while the aircraft is on the ground (Federal Aviation Administration, 2014). This is intended to keep the aircraft from contacting the ground which could cause damage. Additionally, the landing gear absorbs impact as a shock during and aircraft’s landing operation. Finally, the landing gear assists in the take-off of the aircraft by providing acceleration and rotation with the least amount of friction possible (Federal Aviation Administration, 2014). Features of the landing gear designed for the Boeing 737 will be discussed in order to give a more informative depiction of how a landing gear system works.

Let’s say a plane is flying at a constant velocity and is not changing in altitude. Newton’s first law states: “Any object at rest will remain at rest or an object in motion will remain in motion unless a force acts on it.” Newton’s second law tells us that the sum of the forces (F) acting on a body is the mass (m) times the acceleration (a) of the body. In the case of our airplane, there is no acceleration because the velocity does not change up or down, forwards or backwards, so the sum of the forces must be zero. (F = ma = 0) In the case of the up and down forces, we know that the weight of the plane is acting down, so the counteracting lift force must be of magnitude equal and opposite the weight (which can be very large depending on the size of the airplane in question)!

Homeostasis is the term used to describe a body or system in balance, but one of the process the

The airplane is a very normal word today. But it is a new word at least a hundred years. Then I want to talk about airplanes’ history, airplanes’ companies, personal business, global trade, and the benefit for international students and traveling. In my view, those parts are very important about airplanes has changed people’s lives. A lot of people believe that airplanes bring many benefits to our life. I agree with this idea because airplanes are one of the greatest inventions of the twentieth century. So this article will talk about the airplanes.
