The Role and Responsibilities of Aerospace Engineers
Aerospace engineers are the key people for making the next step for humans to travel faster around the world and or getting us more advanced equipment us for getting to space. The definition of Aerospace Engineering, according to Google search, is - The primary field of engineering concerned with the development of aircraft and spacecraft. Aerospace engineers work mostly in manufacturing industries and in the federal government. Furthermore, a select few aerospace engineers are chosen to work on the International Space Station. Most aerospace engineering jobs require at least a bachelor's degree in engineering.:Aerospace engineers may develop new technologies for use in aviation, defense systems, and spacecraft industry. They often specialize in areas such as aerodynamics- a branch of physics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies passing through such a fluid. Structural design- the methodical investigation of the stability, strength, and rigidity of structures. The basic objective in structural analysis and design is to produce a structure capable of resisting all applied loads without failure during its intended life. Guidance- a branch of engineering dealing with the design of systems to control the movement of vehicles, especially, automobiles, ships, aircraft, and spacecraft. Control- an engineering discipline that applies automatic control theory to design systems with desired behaviors in control environments; instrumentation and communication; robotics; and propulsion and combustion. There is also range of problems Aerospace engineers must face before and aircraft can be put into flight. In this research paper we will be talking about the requirements of becoming an Aerospace engineer, the background of Aerospace engineer, and some of the difficulties in putting an aircraft in to flight.
Educational Path and Career Prospects in Aerospace Engineering
Aerospace engineering can be quite a difficult job, but it is a well-paying job and there is always employment almost anywhere you go. Aerospace Engineers make a Average Annual Salary of about $107,830 USD a year on average. Some of the big companies like NASA, Lockheed Martin, Boeing and SpaceX pay an average salary of about $87,922 USD a year for a beginner at their company. To become an Aerospace engineer or work for any the companies mentioned a person needs to get a Bachelor's or Master’s degree in Aerospace, Mechanical, Aeronautical or thermal engineering. Studies of an aerospace engineer include rocket propulsion, Computer Systems Analysis, Calculus, Navigation, Thermal Dynamics, etc. Aerospace engineers has solved a lot of problems in everyday life that people may not have known about. Some of these inventions include: Smoke detector, memory foam, baby formula and LEDs(Light Emitting Diode). Aerospace engineers also continue to help aviation industry by improving fuel efficiency and making lighter aircrafts which makes airline tickets cheaper for consumers.

Challenges and Innovations in Aerospace Engineering
In the text “ Fundamentals Of Aerospace Engineering,” by Manuel Soler, he talks about the key fundamentals of aerospace engineering. The essential sub-subjects of Aerospace Engineering are:
Optimal design: It manages the advancement of efficiently proficient bodies, for example structure of high lift/low drag wings, and nose cone condescending to lessen drag, warming, and the inconvenient impacts of stuns. The significant inspiration of streamlined features is to plan vehicles that furnish the best-streamlined execution with negligible air opposition. Related is the particular zone of Aeroacoustic, which manages the decrease of efficiently created clamor (which has its inception in the stream, and the stream/structure connections). Impetus: It is the investigation of building gadgets used to supply capacity to enable the vehicles to pursue their ideal way. Incorporates the investigation of ignition components, gas turbines, rocket forces and generally current drive systems like electric impetus and plasma helped to burn.
Controls: It is investigation of the elements of the vehicles and their control, with the end goal that the ideal movement is kept up (if enough power is accessible) in a steady way. Control methodologies incorporate gadgets like stabilizers close to the backside of flying machines to keep up longitudinal and directional strength, and rudder,elevator and ailerons to control the air ship's yaw, pitch and move movements. While conventional flying machine plans for the most part prompted stable balance of the airplane (with expanded security yet moderately poor mobility; for warrior air ships it is an incredible inverse once in a while), present day structures will in general make shaky balance which can be settled by electronic input control, and upgrades the mobility extensively. Structures: Deals with the improvement of lightweight yet steady and solid streamlined structures, inside which all the vehicle parts including the drive gadgets and control framework are set. The external structure ought to be sufficiently able to endure the solid streamlined powers (just as powers emerging because of lodge pressurization) and warming emerging because of the quick movement through air.
A decent comprehension of these four principal subjects is basic to plan ethereal vehicles which can move along their ideal trajectory, with least air obstruction with the assistance of impetus units.
Being an aerospace engineer can also be very stressful. According to my mentor Danilo Tagle who works for Genesis Technology, an aerospace company “ One of the most stressful thing about being an aerospace engineer is failure of a project. When were working with certain martials and stuff like that sometimes it does work out and we have to go back to the drawing board and start from scratch with a time limit factor.” He also stated that money is a big factor in the aerospace industry, when things are not funded well it leads to delays or flawed equipment which can be bad when trying to use that equipment after it has been launched into space.
Political and Financial Aspects Impacting Aerospace Engineering
One major problem with Aerospace Engineering is the polictits behind the scenes.One of the reasons we have not been back to moon as yet, is because of polictits. According to Forbes, politics played a big role in us not visiting the moon for very long time. It was back in the mid-1950s, President Dwight Eisenhower actually laid down a sober and methodical timetable for space exploration. He envisioned a fleet of robotic probes that would scout out the moon and beyond. Astronauts would have followed them later, launched on small, fast spacecraft. But when Sputnik's launch was splashed over every front page in October 1957, all of that changed. Suddenly, the race to the moon was all about proving the superiority of capitalism over communism. Arthur C. Clarke, the British author of 2001: A Space Odyssey, once commented that he would have never imagined there would be a push to put men on the moon if it hadn't became the focus of competition between two nations. The last manned mission to the moon was Apollo 17, in 1972.
As Isaac Asimov once commented, we scored a touchdown, then took our football and went home. After all is said and done about what went wrong, the bottom line is simple: money. It's about $10,000 to put a pound of anything into a near-earth orbit. Imagine John Glenn, the first American to orbit the earth, made of solid gold, and you can appreciate the enormous cost of space travel.) It costs $500 to $700 million every time a shuttle flies. Billionaire space tourists have flown to the space station at a reputed price of $20 million per head. And to put a pound of anything on the moon costs about 10 times as much. If politics can’t be put aside when looking to reach space there will always be conflict, which makes the engineers job much harder.With Aerospace being as expensive as it, governments did not see the benefits from it putting a temporary halt on progress the engineers had made.
Future Directions and Challenges in Aerospace Engineering
A real world problem that engineers have problems which is speed. Speed is very important when it comes to spaceship. Engineers want to get the spaceship into space as fast as possible with as little fuel as possible. The larger an object’s mass, the more force it takes to move it and rockets are kind of massive. Chemical propellants are great for an initial push, but your precious kerosene will burn up in a matter of minutes. After that, expect to reach the moons of Jupiter in, oh, five to seven years.
Another problem when it comes to launching a spaceship is trying to find a good spot for it to enter space. Space is loaded with trash that we can not remove at this point in time with the current technology that we have. The US Space Surveillance Network has eyes on 17,000 object each at least the size of a softball hurtling around Earth at speeds of more than 17,500 mph; if a person was to count pieces under 10 centimeters, it’s closer to 500,000 objects. Launch adapters, lens covers, even a fleck of paint can punch a crater in critical systems.
Whipple shields layers of metal and Kevlar and protect against the bitsy pieces, but nothing can save a person from a whole satellite. Some of the 4,000 spacecrafts orbiting Earth, most are dead in the air. Mission control avoids dangerous paths, but tracking isn’t perfect. Taking the sats out of circle isn't practical, it would take an entire mission to catch only one. So beginning now, all satellites should drop out of circle without anyone else. They'll discard additional fuel, at that point use rocket sponsors or sun powered sails to edge down and copy up on reentry. Put decommissioning programs in 90 percent of new dispatches or you'll get the Kessler disorder: One crash prompts more impacts until there's such a great amount of poop up there, nobody can fly by any stretch of the imagination. That may be a century subsequently or a great deal sooner if space war breaks out. In the event that somebody begins exploding adversary satellites, it would be a catastrophe, says Holger Krag, head of the Space Debris Office at the European Space Agency. While Aerospace Engineers go through a lot of stress it is still n one the most revolutionary industries. The job pays well, a person is meat with new and different task to complete which involves creativity.
