When in orbit the shuttle is positioned so that it is moving nose-first and the top of the shuttle is pointing towards the earth. The shuttle is positioned "bottom up" so that the black bottom will radiate the heat from the sun more effeciently. Step one for the shuttle is to turn around so that it is moving stern-first and then it fires it's engines in order to slow the shuttle so that it will drop out of orbit. Next the shuttle flips over so that it is right-side-up when it enters the atmosphere. Between step three and four the shuttle burns any excess fuel that it may still have so that there is less of a danger of explosion when the fuel tanks get hot durring re-entry. Step four is where the shuttle maintains an angle of about 40 degrees from the vertical and maintains an approach so that the shuttle slows down. After slowing to a speed where the shuttle can maneuver it will "fly" (remember, the shuttle has no more fuel so it has only one chance to land) in some final S shaped curves to slow some more and then land at a designated airport (as shown below).
How Does the Shuttle Turn or Maneuver in Space?
The basic means of movement for the space shuttle can be explained in Isaac Newton's laws F=Ma and for every action, there is an equal and oposite reaction. The force, on the space shuttle, is equal to the mass of the shuttle multiplied by its acceleration. By burning fuel in a rocket engine on the back of the shuttle, a force on the shuttle equal to the mass of fuel being "thrown" out the stern of the craft multiplied by its acceleration. This basic physics formula is very important to the shuttle getting up into space and to the beginning of its deceleration on its return to earth. Thus it has a very real impact on weather the shuttle will survive the trip through the earth's atmosphere back to land. When the shuttle first enters the earth's atmosphere it is traveling at speeds topping 30,000 km/h. The shuttle has to decelerate to 0 km/h after it lands. The acceleration that it must endure to slow the shuttle is an incredibly large force on the structure of the craft.
When the shuttle is entering the atmosphere it must enter at an angle window of only a few degrees.
Cost management plays a major role when maintaining profit margins. Management must be able to find in which areas of a business costs must be reduced and the consequences that such reductions have in the overall company. In some situations management must change the way the work is being done in order to decrease costs while in other cases changing one supplier for another might be enough, in both situations a tradeoff will occur and the consequences will impact the company as a whole.
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.
A shuttle is the size of a jetliner, lifts into space using powerful boosters, and returns to Earth as a glider due to its aerodynamic wings. Launching like a rocket, it orbits the earth like a spacecraft and lands like an airplane ("Shuttle Basics," par. 1). It takes eight and a half minutes for the shuttle to reach space, it travels at 17,500 miles per hour, and the crew can see the sunrise or sunset every 45 minutes ("Space Shuttle Program," par. 3). The shuttle consists three main parts: the Orbiter Vehicle, two Solid Rocket Boosters, and the External Tank.
Many people are amazed with the flight of an object, especially one the size of an airplane, but they do not realize how much physics plays a role in this amazing incident. There are many different ways in which physics aids the flight of an aircraft. In the following few paragraphs some of the many ways will be described so that you, the reader, will realize physics at work in the world of flight.
On February 1, 2003, the Space Shuttle Columbia was lost due to structural failure in the left wing. On take-off, it was reported that a piece of foam insulation surrounding the shuttle fleet's 15-story external fuel tanks fell off of Columbia's tank and struck the shuttle's left wing. Extremely hot gas entered the front of Columbia's left wing just 16 seconds after the orbiter penetrated the hottest part of Earth's atmosphere on re-entry. The shuttle was equipped with hundreds of temperature sensors positioned at strategic locations. The salvaged flight recorded revealed that temperatures started to rise in the left wing leading edge a full minute before any trouble on the shuttle was noted. With a damaged left wing, Columbia started to drag left. The ships' flight control computers fought a losing battle trying to keep Columbia's nose pointed forward.
In this paper you will learn so much about rockets you can become a rocket specialist. Many may ask how do rockets work? Many will respond that they are pushed against something but that is wrong. Since rocket's main purpose are to travel in space where there is nothing, not even air they can not rely on “something” to push themselves against in space. This is the right answer to how rockets work; Rockets use fuel, they burn the fuel and it turns into hot gas.
R. M. Boisjoly had over a quarter-century’s experience in the aerospace industry in 1985 when he became involved in an improvement effort on the O-ring which connect segments of Morton Thiokol’s Solid Rocket Booster. This was used to bring the Space Shuttle into orbit (OEC, 2006). Morton Thiokol is an aerospace company that manufactures the solid propellant rocket motors used to launch the Challenger (Skubik). Boisjoly authored a memo to R.L. Lund, Vice President of Engineering and four others, in regards to his concerns about the flawed O-ring erosion problem. His warnings were ignored leading to the deaths of six astronauts and one social studies teacher.
It was on January 28, 1986 at 11:38 A.M. that the shuttle Challenger, NASA flight 51-L, the twenty-fifth shuttle flight, took off. It was the "Teacher in Space" mission. At lift-off, the temperature at ground level was 36° Fahrenheit, which was 15° Fahrenheit cooler than any previous launch by NASA. It was the Challenger's tenth flight. Take-off had been delayed several times. Finally the shuttle had taken off. The shuttle had climbed high in the sky thirty-five seconds after take-off, and it was getting hit by strong winds. The on board computers were making continuous adjustments so the shuttle would stay on course. About eight miles in the air, about seventy-two seconds after take-off, people watched in fear and horror as the shuttle was engulfed by a huge fire ball. All the crew members were killed instantly.
In order for any rocket to fly, it must obey some basic rules of physics. No rocket can escape the cardinal rule that the center of gravity must be in front of the center of pressure.
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.
as the shuttle can go up to speeds way over 100miles per hour during a
Bottle rockets are great models to examine Newton’s three laws of motion. The bottle rocket will remain on the ground until an unbalanced force, water, thrusts the rocket upward. This is defined by Newton’s first law of motion: an object at rest stays at rest or an object in motion, stays in motion (in the same direction/at the same speed) unless acted upon by an unbalanced force. It is also known as the law of inertia.
Flight uses four forces: lift, weight, thrust, and drag. In a nutshell; so to speak, an airplane must create enough lift to support its own weight. Secondly, the airplane must produce thrust to propel itself. Finally, the aircraft must overcome the drag or the force of resistance on the airplane that is moving through the air. All four of these forces are vital and necessary for an aircraft to move, takeoff, fly, and land.
Subsequently, this kind of the long-distance effect had to occur more and more away from the position of launching to prevent self-damage. Therefore, the fulfillment of a long dream of the human race, to be able to fly, came just in time – and now, not everything that came from above was good anymore.
Relating to the Audience: I believe that the Space Shuttle program has fascinated most if not all of you at some point of time, so much so that it has driven some of us to pursue Aerospace Engineering. Thus, it is a good idea to explore the program’s end result, the reason why it was started in the first place – To build the International Space Station.
