With the collapse of the NASA space program, getting into space has moved to the private sector. Private companies such as Virgin Galactic, SpaceX and Starchaser Industries are all working on developing craft that can take the average person into space. Space travel will be common place in the near future. Aeronautics comes from the greek word “aero” or air and the word “nautique,” of ships. Aeronautical Engineering is a branch of engineering science concerned with the design and construction of aircraft. This field is similar to mechanical engineering. However, their differences are in their specialties. Aeronautics focuses on aerodynamics. Aerodynamics is the study of shapes and their resistance to friction caused by the atmosphere. Aeronautics also deals with propulsion (engine), lightweight materials and material strength. This Diagram is an example of what type of designing that an aeronautical engineer might do. This is a cut away diagram of an oxygen fueled rocket booster that is used on satellites. It is used for propulsion. Mechanical Engineering is a discipline of engineering that has a broader scope of understanding in the field. Aeronautics focuses on a single aspect while mechanical engineering covers multiple areas of knowledge. In any case, the proper description of a Rocket Scientist is anyone that is involved in the design, construction or launch of a vehicle that is designed for space travel. The individuals that work on projects like these have a bachelor’s degree or higher in one of the following fields. Physics: A science dealing with the physical nature of things as they are subjected to properties that control our universe. Electronics: A science that specializes in the properties of electricity. Astrology: This is the study of stars and our position in the Universe. Last but not least is the study of Engineering. This field of study is used to design a product that will perform according to the specifications required by the other sciences research. Digital renderings made from data collected during tests show how the air moves over an air frame. The different colors represent temperature change due to friction. 2 Rocket Propulsion Technology How it works Typical rocket propulsion consists of a reaction wherein both the fuel and the oxidizer, generating the hot gases expended through a nozzle, are carried as part of the rocket engine. Specifically, rocket propulsion differs from jet propulsion in that jet propulsion utilizes atmospheric air as an oxidizer, whereas rocket propulsion utilizes nitric acid or a similar compound as an oxidizer. There are three different types of propulsion systems utilized for non-atmospheric conditions (space): Plasma Propulsion Systems (PPS) Mono Propulsion Systems (MPS) Unified Propulsion Systems (UPS) Skills required System and Propulsion Engineering. Propulsion Function Analysis. Propulsion design, manufacturing and test. Plasma Propulsion Systems 1. Propellant is fed into a chamber where it is excited to the point of electron transmission. 2. RF generators provide the energy required to excite the gas 3. Magnetic superconductor coils generates a magnetic field that directs the excited electrons out of the engines nozzle. This method of propulsion can generate sufficient thrust with a minimum amount of fuel consumption. This method is ideal for uses in attitude and orbit control in communications satellites or interplanetary travel. Similar to two magnets that repel each other, the magnetic fields repels electrons out of the exaust nozzle. 3 Mono Propulsion System The simplest of the three propulsion designs does not require in oxidizer to burn its fuel. For monopropellant rockets that depend on a chemical reaction, the power for the propulsive reaction and resultant thrust is provided by the chemical itself. That is, the energy needed to propel the spacecraft is contained within the chemical bonds of the chemical molecules involved in the reaction. The most commonly used monopropellant is hydrazine (N2H4), a chemical which is a strong reducing agent. The most common catalyst is granular alumina coated with iridium. There is no igniter with hydrazine. Shell 405 is a spontaneous catalyst, that is, hydrazine decomposes on contact with the catalyst. The decomposition is highly exothermic and produces an 1800 °F (1000 °C) gas that is a mixture of nitrogen, hydrogen and ammonia. These motors are much like what you find a bottle rocket. Unified Propulsion System A combustible liquid such as nitrogen or hydrogen is mixed with a oxidizer like liquid oxygen. The mixture is ignited to produce thrust. This system has the capability to work in space because of the addition of the oxidizer. This system is the most commonly used in space travel today. 4 Aerojet Project Engineering Specialist - Controllable Solid Location: Sacramento (Rancho Cordova), CA 95670 Job Category: Engineering Reference Code: 7159 Aerojet is a world-recognized aerospace and defense leader providing propulsion and energetics to its space, missile defense, strategic, tactical missile and armaments customers throughout domestic and international markets.

The purpose of this interview was to learn about the company from one of its employees. Questions concerning the company’s mission as well as employee relations were discussed. Print Material Other sources of information used were documents from the Tesla website. These documents include a letter from the CEO Elon Musk and lead engineers about Tesla Motors. Other information about the company was also gathered from the Tesla website. The reason for this method of research is to collect as much data from the perspective of the company as possible. In order to provide an un-biased analysis of organizational culture, perspectives from multiple sources must be collected. Electronic Sources Finally web searches were done to collect information about Tesla that isn’t produced by the company itself. Online magazine articles, blogs and reports written by non-affiliated sources. This was done to give another perspective into the inner workings of the company. These methods are not without their faults. Even though I may have gathered information with the intent on providing a non-biased look into a company, who is to say that the sources are not biased. The information that I gathered is also limited to web searches and minor research done in a library. My methodology in finding data on the subject is not as thorough as a professional journalist. 7 Resume Brandon Corwin 2005 McClelland Street Salt Lake City, UT 84105 Phone: 801-918-6501 Email: DjPush_slc@yahoo.com Career Objective A position as mechanical engineer in the aerospace industry, specializing in propulsion systems or high altitude low orbit vehicles.
