3 Famous Engineers From Aerospace, Chemical And Electrical Engineering Backgrounds

Aeronautical Engineering is focused only on Aircrafts that do not leave the Earth's atmosphere whereas Astronautical Engineering is focused on Aircrafts that are able to leave the Earth's atmosphere. Initially this industry was focused on Aeroplanes and flight technology but it has expanded to also run the operation of outer space aircrafts. Some of the issues that Aerospace Engineers have to deal with include temperature change and control, atmospheric pressure and flight planning. They deal with these issues by using technologies such as aerodynamics, avionics, propulsion and material science.

Wernher von Braun

Wernher von Braun made a significant impact in the development and advancement of rocket technology in America and Germany. However, some found his work very controversial because he did some work on a Nazi rocket programme and there was even a song written about him! Wernher had an interest in space and astronomy from a very early age and his mother supported his interest by buying him a telescope.

Wernher went to the Berlin Institute of Technology where he became a prominent member of the Spaceflight Society. A few years later he earned a doctorate in physics and received a research grant to work on a rocket test site.

Chemical Engineering

Chemical Engineers work to combine both Chemistry and Engineering in an intelligent way in order to closely study the production of chemicals.

Henry Bessemer

Bessemer was an English Engineer born in 1813. He is best known for his division of the Bessemer process which was used in the manufacture of steel. This was a very well known process that was implemented worldwide and was very important to the industry at the time. It resulted in steel dropping significantly in price and being used for a huge variety of things for the first time. Bessemer invented another very important process, the decarbonisation of cast iron. He also invented a great deal of other things and coming up with revolutionary ideas was his passion.

Electrical Engineering

Electrical engineering is centred around the study of electricity. However, what many people don't realise is that it covers a variety of subjects and industries such as electromagnetism, control systems, telecommunications and power.

Thomas Edison

Thomas Edison was an American businessman who also spent a great deal of his time attempting to come up with new inventions. Consequently he invented a wide range of useful ideas and devices. He was most famous for using the principles of mass production to enhance the process of invention. Thomas Edison came up with so many ideas that he ended up obtaining 1,093 patents for his vast array of inventions.

What does an electrical engineer do?

An electrical engineer is a specific type of engineer. Electrical engineers work with a variety of different electrical components. Most electrical engineers have a specific field of expertise – such as computer components or automotive engineering – and this is where they really get to create remarkable new technology.

When an electrical engineer works on a project, he'll usually be given a brief by a client, or be presented with a problem and asked to come up with a solution. The electrical engineer will then create a plan – maybe even a 3D map – of the component they're creating. This will include all the circuitry and wiring.

The next step is to build a prototype of the component, and test that prototype in all kinds of different situations. There will be stringent safety tests to pass, as well as making sure all the components work together the way they should. Only once all the tests have been completed and the design modified and re-tested can the electrical engineer put a component into construction. But his/her job is still not over – for he/she may be required to perform maintenance or repair on the components over the years.

An electrical engineer is often part of a team of engineers, so they have to understand not just electronics, but other types of engineering as well. It's important that an electrical engineer can work well alongside other colleagues to produce the most efficient, cost effective and quality product.

Many electrical engineers will specialise in a particular type of technology, for example switch mode power supplies engineers. In order to become an electrical engineer, you'll need to go to university and obtain a Bachelor's degree in engineering with an electrical engineering speciality. Many engineers who wish to specialise further than that will go on to postgraduate study or choose a particular course of study. To be a good electrical engineer, you'll need to have a decent background in physics, mathematics, design (computer-aided), processing and production.

Above all, electrical engineers need to be quick thinkers with a real attention to detail and the ability to think laterally about any problem.

Getting a job as an electrical engineer

You're just out of grad school and looking for a job. Perhaps you're a general electrical engineer, or maybe you've specialised as a transformer engineer, but either way, there are too few jobs for so many graduates. What are your chances of landing a job as an electrical engineer in this economy?

Despite what you may think when you're not getting any results from sending out your resume, there are a shortage of electrical engineers in New Zealand, according to Department of Labour estimates. "Electrical Engineer" appears on New Zealand's "long-term skill shortage" list at Immigration, which means immigrants with electrical engineering degrees are being encouraged to come here. Instead, you should be applying for those jobs.

The NZ Government is spending more than ever on infrastructure, and with that comes increasing opportunities for qualified electrical engineers. The government has confirmed in the 2011 Budget it will be spending a further $3.8 billion updating the national grid, so you'll be seeing more and more opportunities for electrical engineers as this project progresses.

And, don't forget, the new sustainable energy market is creating more jobs for specialised electrical engineers. The increased use of wind power, solar power and hydro-electrical schemes demand specialist skills, and would be a fascinating area for any electrical engineer interested in specializing.

As an electrical or transformer engineer, you'll either be working for a major power company, or for an engineering consulting firm as part of a team of specialised engineers. The work will vary between designing new systems, implementing new electrical technology, and maintaining and troubleshooting the current systems.

If you want to stand out amongst the other engineering candidates, the first thing you should do is approach major companies and power suppliers about internship programmes and work experience opportunities. Each year these companies take on a certain number of graduates as part of these programmes and it is to the standout graduates in this pool that they offer jobs at the end of the internship period. If you can land an internship and prove yourself a competent and efficient employee, then you can find yourself with a job offer as an electrical engineer.

What is Electrical Engineering Today and What is it Likely to Become?

So what is Electrical engineering, as distinct from computer engineering, and what is its future? We address this question by examining it from the perspective of university Electrical engineering programs and the needs of industry and society. As a result of our investigation, we also develop a definitional set of broad areas and specialties that define Electrical engineering, both now and in the future. We conclude with a recommendation to give Electrical engineering more curb appeal for prospective students. The perception of service to society is important in attracting students. Electrical engineering has historically been critically important to society. If whatever form Electrical engineering takes in the future continues to be of critical importance, we need to be able to convey this to prospective students and attract them to the field.

A DEFINITION OF ELECTRICAL ENGINEERING

There are certain broad areas that are important to Electrical engineering across the board. In addition, there are prominent specialties that many may consider a subset of one or more of the broad areas, but they are notable in that they are distinctively Electrical engineering. We propose the four following broad areas that are fundamental to Electrical engineering (in no particular order):

• Electromagnetics and Optics: The entire field of controlling electromagnetic phenomena,

electromagnetic waves of all frequencies, including optical, are clearly the domain of the electrical engineer.

• Signals Engineering: The processing of signals that historically have been generated by electrical or

electronic devices and electromagnetics remains a critical domain of the electrical engineer. Where once

the signals were processed by analog devices and continuous time mathematics, today digital signal

processing dominates. Many signals today are important in bioengineering.

• Systems Engineering: By this we mean solving complex problems that can be modeled by, in general, complex calculus based matrix mathematics. Historically, this included such things as state space equations, convolution, mathematical transforms, minimization/maximization problems, etc. whether analog or digital. In particular linear system theory has been a cornerstone of advanced electrical engineering work, and we should retain the ownership of it. The interdisciplinary nature of the world today makes systems engineering indispensable.

• Electronics, Microelectronics, and Circuits: This allen compassing field has long been the domain of the electrical engineer. The understanding of this area remains important, and competent electrical engineers, even if they are not designing circuits, still need to know how circuits work. The semiconductor area still needs competent electrical engineers, and there are predictions of a bright future for engineers in this area . Power electronics is important to the electric power industry. Photonics is here to stay. There is demand for consumer electronics, avionics, navigation, vehicular electronic systems, and computer components. The four specialties we propose are listed below. Again, some may contend that they are subsets of the above broad areas, but that is fine. These specialties in particular help characterize Electrical engineering

• Telecommunications and Radar: This is the specialty that has evolved from traditional radio engineering, and includes wireless communications, radar, remote sensing, networks, wired communications, information theory, error correction coding, detection and estimation theory, etc. Today, telecommunications is playing a larger and larger role in medicine and radar is helping us understand climate change. Where once all radio devices were constructed with analog electronic components, today much of the signal processing is done with software. However, it doesn't matter how the systems are constructed; it is still telecommunications and radar and the domain of Electrical engineering.

• Electric Power Systems: The generation and transmission of electric energy including alternative sources of energy and the impact on society and the planet is an important part of Electrical engineering. Although not many Electrical engineering programs offer power emphases anymore, we propose that at a minimum a set of power electives should be available. This is clearly an area where future Electrical engineering's can help make a difference in the world, and it is also an area where an interdisciplinary approach is crucial, e.g. economics, network theory, political science, law, etc.

• Instrumentation and Control: Both instrumentation and control systems are classic domains of Electrical engineering. Much of classic control theory is an integral part of what we have labeled systems engineering, so the heavy mathematics may more appropriately belong there. With instrumentation, we deal with transducers. The signals today may be represented digitally, but we feel that transducers, the building of these devices, and the processing of the signals remain the domain of EE. This specialty also includes robotics. And one notable Electrical engineering contribution, among a number, to the biological revolution is in the area of medical instrumentation.

Future Trends in Electrical Engineering

The future of electrical engineering looks very bright. This is a profession that's exploded over the last several years. With the popularity of computers and the future of computers, electrical engineering careers will probably be in even more demand. Just about every industry needs computers and that means that electrical engineers will always be needed. So this is a great career to go into and it will continue to be for many, many years to come.

When staying in an electrical engineering career there are many different jobs that can be held. And there are many different job titles that go along with all the different jobs. The job titles include electrical engineer, development engineer, field engineer, project engineer, design engineer, systems design engineer, and test engineer. Most of these job titles explain basically what each job entails. Though there is obviously much more to each job than you'd know at first glance.

The jobs will require the electrical engineer to do things such as design, develop, and implement products or services. The electrical engineer may also be expected to research and come-up with new ideas. Some of the tasks can and will be very challenging but with the proper education and the proper training an electrical engineer will be able to perfectly complete every task and solve every problem.

Electric Generator - Types and Usage

Electric Generator is commonly used as backup systems in several residential and commercial areas. These types of generators work on the principle of converting mechanical energy into electrical energy with the help of a motor. Separate electrical circuit provides the flow of electrons into the windings of the generator. Conversion of mechanical energy into electrical energy is done with the assistance of a turbine steam engine, wind turbine; hand crank compressed air, internal combustion engine or energy of falling water is tapped through a water wheel or turbine.

Today power cuts are frequent. You cannot afford to lose business because of a power cut. Hospitals particularly may face life threatening situations as many life saving medical equipments work on electricity. Hence, in recent years the demand for standby and portable generators has increased manifold.

Size and voltage is an important factor to consider before buying emergency equipments. Electric generator can be divided into four categories, recreational, standby, portable and commercial.

The recreational generators are usually used for RV's that is recreational vehicles particularly used for camping. Camping is mostly done in remote places and apart from the battery backup of the vehicle additional power is required to light up some basic appliances and devices that the modern RV's are equipped with.

Two types of recreational generators are available, 1000 watts and 2000 watts. The 1000 watts equipment will aid in running only about one or two appliances like coffee maker or toaster and 2000 watts should ideally help in running multiple appliances.

Recreational generators cannot be used at home due to limited capacity. Portable generator that comes in medium, large and extra large sizes is a good option. These are for purely emergency backups. They vary from 3000 watts to 10,000 watts in power. A 3000 watts medium sized generator will only supply power to tube lights, fans, furnace fans, refrigerator and some more small appliances but not to air conditioners. Principally for central air conditioning, you would require 9000 to 10,000 watts electric generator.

Standby generators are constantly plugged in with main utility supply line, consist of an automatic on and off switch, which keeps you tension free from keeping a check on fuel or gas levels unlike portable generators. While buying standby generators it is imperative to check the number of circuits and wattage required for various types.

Three kinds of standby devices are available in the market with varying potency like powering whole house, essential circuits and smart circuits. The wattage requirement varies from 8 KVA to 48 KVA and starts from utilizing 8 to 16 circuits to complete circuit board respectively. Standby electric generators are considered to be the best today for residential use.

For commercial employment, large sized generators are used that are usually tailor made as per requirement. Large offices and commercial centers typically use this type of generators. These generators work on three phases and exploit diesel or natural gas. Natural gas is a better source as it produces less exhaust waste and is less noisy. Electric generator that best suits your needs is the one that is compatible with your incoming utility voltage.
