This report, focusing on the Atlas V (spoken Atlas five) rocket, a launch system designed to send payloads into orbit of the Earth and beyond , will outline the following in specific detail:
• The original design mission of the Atlas V launch system
• The structural design and construction of the Atlas V launch system
• Unique aerodynamic features of the Atlas V launch system
• The propulsion systems contained within the stages of the Atlas V launch system
• The operation requirements of the Atlas V launch system
• The safety features and safety record of the Atlas V launch system
The Atlas V was chosen as the focus of this report for two specific reasons. Firstly, the combination of Russian and United States technology, …show more content…
The Evolved Expendable Launch Vehicle program was designed to ensure the United States’ access to space, by creating government contracts for commercial companies to bid for, secured by a presidential decree . The Atlas V was created for this program, coming from a line of Atlas rockets, being the latest in its family. It replaced the Atlas III and later replacing some flights of the Delta IV, a rival rocket developed by Boeing . The Evolved Expendable Launch Program requires for bidding rockets to have the ability to send satellites and/or humans into orbit.
The Atlas V was designed solely as a launch system to deliver a wide variety of payloads into space. It’s initial launches were US satellites with its first flight containing a military communications satellite . The Atlas V has not been rated to contain human passengers, and currently only functions to take satellites to orbit and escape trajectories. However, the Atlas V is currently undergoing tests with the CST-100 Starliner, to be able to take humans into orbit, with manned missions hopefully taking place in 2018 .
Thus, the Atlas V’s original mission design came about due to the EELV program of the United States and continues to function to its original purpose by shuttling payloads to orbit and …show more content…
The Atlas V has 2 main propulsion systems, one in each stage of the rocket, and optional propulsion systems depending on the payload . Within the first stage of the Atlas V is the RD-180 engine, which is initially used before the stage is decoupled and the second stage Centaur engine activates. The payload, depending on its nature may have its own propulsion system, however, varies depending on the payload.
5.1 The RD-180 Engine
The RD-180 engine utilises LO2 (Liquid Oxygen) and RP-1 (Rocket Propellant-1, a refined form of kerosene) as its fuel mixture, with a ratio of 2.72 for oxidiser to fuel . The RD-180 engine utilises a twin chamber design, which is fed by the commonly used turbopump configuration, allowing for the fuel and oxidisers to move out of the two chambers. The RD-180 engine uses an Oxygen rich pre-burner, which provides a greater fuel to thrust ratio, however, high pressure hot gasses must be transported within the engine, as seen in fig 2, which could lead failures within the

The Space Race was a time of competition between to two Cold War rivals, the US and the Soviet Union, in the discovery and exploration of space. The Space Race was a part of the Cold War and was another form of competition between them. This competition during the Space Race for breakthrough research in space exploration led to discoveries about space in a period of time that has not been rivaled by discoveries made after the end of the space race and the decrease in competition. This competition created an emphasis on researching space and shortened the time it would have most likely taken had there been no rivalry. The Space Race is considered to have started when the United States announced their plans for a satellite and the Soviet Union announced the same thing a few days later.
Section B: Summary of Evidence American Inferiority to Soviets • Soviet’s Sputnik device was eight times heavier than what the U.S planned and launched much sooner. • Soviets claimed to understand American “difficulties” but disclaimed their competition with America in conquering space. Improved Space Technology • American fears were provoked because the Soviets were able to launch a major space technology while the United States had failed twice. • Prior to Russian launch of Sputnik
Now that the Space Race is over, what is the point? Are we wasting our money? Should we cut their budget? When the cold war ended with the soviets in 1991, it sparked up a debate as to whether or not the funding for the National Aeronautics and space administration should be continued. Although it may seem like a simple fix, it has proved to be one of NASA’s greatest and most difficult challenges yet.
It took centuries and nearly half of the continents to bring about such a weapon. Its towering frame and sling capable of launching missiles over 300 pounds was created by some of the most innovative people across the Eastern Hemisphere. Such a weapon was built for destruction, the trebuchet’s specialty being
It wasn’t just about funding though, it was also about getting to the moon and placing a man there, getting past the boundaries and having further in-depth knowledge of our solar system. Kennedy’s
The Atlas program was inspiring and increased the pride of American citizens by getting them involved in the highly successful program. The program that put the U.S. back in the space race boosted the morale and national pride, and also encouraged the progression of space exploration for the
Canada's Identity as a World Power in Aerospace Technology The CanadArm is one of Canada's most famous and greatest robotic and technological achievement. The CanadArm made its debut on the Space Shuttle Columbia (STS-2) on November 13, 1981. The CanadArm served the National Aeronautics and Space Administration (NASA) for approximately 30 years. During its career with NASA’s Space Shuttle Program, the robotic arm deployed, captured and repaired satellites, positioned astronauts, maintained equipment, and moved cargo.
The main outreach of the United States government that explores new boundaries never investigated before, designs products never thought possible before, and most importantly inspires people, has had its budget slashed. According to Goldstein (2007), NASA was originally created to beat the Soviet Union in the Space Race has taken on many different roles. In an article for NASA’s website, J.R. Wilson (2008) uses Dr. Michael DeBakey, a heart surgeon, as an example of someone who felt the benefit of NASA’s wide research scope. Dr. DeBakey now uses a heart pump in surgerys, invented because of the research done by NASA (Wilson, 2008). One of NASA’s many inventions that directly improve the lives of Americans.
After the abrupt cancellation of the program and the estimated 14 000 Avro employees fired, many of Canada’s highly educated scientists had emigrated, causing a problematic brain drain. Instances include chief engineer of the Arrow, James Floyd, who helped with the development of the Concorde Jetliner in Britain. Along with Avro’s chief aerodynamicist Jim Chamberlin, who assisted with the development of the National Aeronautics and Space Administration’s (NASA) Apollo and Gemini space programs. It is argued that the Arrow Program was an economic burden and thus the reason it was canceled. However, according to author Palmiro Campagna, the completion of the aircraft would stay within approved economic boundaries and allow for sufficient social funds without causing the nation to go bankrupt.
Other: According to Master Sargent Mitch Gettle of The United States Air Force, the USAF mission statement reads, “The mission of the United States Air Force is to deliver sovereign options for the defense of the United States of America and its global interests...to fly and fight in Air, Space,
In addition to the space capsule the rockets used for Project Mercury where also equally impressive. For Project Mercury there were two different types of rockets used to support this program the Mercury-Redstone rocket and the Mercury-Atlas Rocket. The Mercury-Redstone rocket was originally from the Army Redstone and Jupiter-C missile’s and was modified to meet project objectives. The modifications included increased fuel tanks, newly designed engine, new instrument compartment in the upper section, a control system, an abort system, and new instrumentation to relay information on the performance of the rocket.
The data proves that the size of the fins do impact the height of the rocket. When launched with the small fins, the rocket reached a height of 38.35 meters and had a time of 5.54 seconds. The larger fins appeared to make a difference in the height. The height achieved with the larger fins was 48.82 meters and accomplished a time of 6.25 seconds. This data proves that the hypothesis was correct.
The use of the commercial industry in space activities has always been questioned. Throughout the space age the U.S. space program has used the commercial industry in several different ways. Without it the space program would not be where it is today, however it still has a long way to go. Linster pointed out that he believed that the commercial industry needs to play a larger role and expand as the U.S. space program evolves over time.
For instance, the congressional bill authorizing the POTUS to move items from the USML to the CCL, highlights the shift to expand commercial use of space and the expansion of U.S. space companies (Bureau of Arms Control, 1967). The shift in focus toward U.S. commercial space companies through space launch, commercial crew and cargo vehicles is offering U.S. space companies expanded opportunities both nationally
Aircraft Performance Through the chaos and mayhem of World War 2, the aviation industry made significant advancements in its technology. After the war ended, this technology stretched and expanded to the farthest reaches of the world. Frank Whittle of England and Hans von Ohain of Germany both created the world of aviation that we live in today. Both men did it without the knowledge of each other throughout the 1930s and 1940s.
