Aerospace engineering,Aeronautical engineering,Astronautical engineering,Courses and Career Prospects

Aerospace engineering is one of the most popular courses in engineering. There are several institutes which offer Aerospace engineering courses. Candidates who successfully qualify all the eligibility criteria get a chance to pursue their higher studies. Career training in Aerospace engineering can get you, your dream job in a prestigious organization. Aerospace engineering is broken into two major and overlapping branches: aeronautical engineering and astronautical engineering.

Aeronautical engineering

Aeronautical engineering is a branch of aerospace engineering, though some people use the two terms interchangeably. Aeronautical engineering includes aircraft design, and the management of the physical forces that act on aircraft. These primarily include the sciences of propulsion and aerodynamics.

Aerodynamics is at the heart of aeronautical engineering. This is the study of the relationship between air and solid materials. Aeronautical engineers place particular emphasis on the design of wingsor airfols. An airfoil is a device that uses its shape to produce lift when moved through air, thereby counteracting the force of gravity

Aeronautical engineers tend to specialize in one or more of the areas above, but at the same time, they must be prepared to work in close cooperation with other specialists involved in designing aircraft. It is not unusual for them to have Master’s degrees, or even Doctorates in their chosen field of specialization. The first airplane was designed by a pair of bicycle makers, who worked on it largely as a hobby. But a modern airplane is an incredibly complex device, and designing one often requires the collaboration of hundreds of people. Aeronautical engineers make up a fundamental part of this collaboration.

Courses and Career Prospects in Aeronautical Engineering

The basic degree required for becoming an aeronautical engineer is a B.E. (Bachelor of Engineering) or a B. Tech (Bachelor of Technology). One can also acquire a diploma in Aeronautical Engineering. Most of the reputed engineering colleges offer degree and post-graduate degree courses in Aeronautical Engineering. In order to pursue a B.E. or B.Tech Course in Aeronautical Engineering, one needs to qualify the higher secondary examination with Physics, Chemistry and Mathematics as compulsory subjects along with a good aggregate percentage.

Candidates should also have good observation power and an analytical bent of mind. They should also be a good communicator and crisis manager besides being healthy and fit. A student who does not have a sharp eye sight and is color blind may not qualify to become an aeronautical engineer even though he may be academically brilliant.

Aeronautical Engineering Courses imparts multi-faceted training to students in areas like manufacturing and development of aircrafts and missiles. An aeronautical engineer can also design, test and contribute to the development of advanced technologies in the field of defense and space science. Initially, candidates begin work as graduate engineer trainees or junior Engineers. Keeping in view their performance, academic background and aptitude, they are placed for training in the aircraft maintenance/overhaul or support section. On completion of training they are placed as assistant aircraft engineers or assistant technical officers. They have to clear departmental examinations for further promotions. They may advance to administrative or executive positions or become consultants. Aeronautical engineers are assisted by aircraft mechanics in maintenance of aircraft frame, engine, electrical system and other ancillary fittings.

A lot of job opportunities for aeronautical engineers are also available in the countries like United States of America, France, UK and Germany. Therefore, aeronautical or aviation engineers from all other parts of the world flock to these countries.

Astronautical engineering

Astronautical engineering deals with vehicles, instruments, and other equipment used in space, but not with the sociological or economic aspects of space flight, except as they influence the equipment.

There is a lack of parallelism between astronautic and aeronautic vehicle terminology. An aircraft is a self-contained vehicle, having within its structure essentially all the equipment required to transport its payload from one place to another. In a restricted sense a spacecraft is the container for the payload. Sometimes the word is used to denote the container and payload. Most spacecraft, to date, have had either very limited propulsion or none at all. Since enormous speeds are the hallmark of all astronautic missions, un powered spacecraft require a “booster,” or “launch vehicle,” usually a rocket many times as large as the spacecraft. The weight of the spacecraft, in fact, seldom exceeds 5% of the total launch vehicle weight.

Astronautical engineering is a branch of practical science that deals with the design, building and theories of spacecraft. Often referred to as rocket science, astronautical engineering is an incredibly complex field of the aerospace industry that requires extensive training and a deep understanding of physics, engineering, and outer space. For all its complexity, modernastronautical engineering is a relatively young field, dating back to the first spacecraft flights of the 20th century.

Many jobs in the astronautical engineering world require graduate degrees in the field; candidates usually have either amaster’s degree or a PhD with an emphasis in their area of interest. Some technical jobs are available to those withbachelor’s degrees in engineering as well. Job opportunities for astronautical engineers can be either in the public or private sectors; while some countries have active space programs that employ engineers, many work for private contractors that build rockets, missiles, and other spacecraft.

Flight vehicles undergo severe conditions such as differences in atmospheric pressure, and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, propulsion,avionics, materials science, structural analysis and manufacturing. These technologies are collectively known as aerospace engineering. Because of the complexity of the field, aerospace engineering is conducted by a team of engineers, each specializing in their own branches of science.

Tummy tuck or abdominoplasty surgery

Are you worried of your belly fat? Worried of your shape? Then Tummy tuck is a good choice, especially for women. Many women who have had one or more deliveries feel unhappy because of the loss of their pre-pregnancy shape. Though a wonderful experience, pregnancy adversely affects skin elasticity and muscle tone and causes stretch marks. A tummy tuck would correct sagging skin and tighten the stretched areas, thereby restoring the patient’s body shape.

Tummy tuck

The tummy tuck is an ideal solution for stubborn surplus fat that is unresponsive to exercise and a controlled diet. The doctors’ name for tummy tuck is abdominoplasty surgery. Tummy tucks are meant to take fat from your stomach and also take the flabby skin from around your abdomen. Your stomach muscles will also be tightened and this may make them stronger. The tummy tuck should not be considered as a procedure for losing weight. Candidates for the treatment are either already in their normal weight or quite close to it.

A tummy tuck can be done under local anesthesia or a general anesthesia, but most people opt for a general anesthesia for this procedure. It involves an incision from one hip to the other. A second incision will then be made to remove your navel. A final step in the tummy tuck procedure is to remove the skin and fat from the wall of your abdomen and tighten the muscles there. Afterwards the skin is stretched over the abdomen again and any excess is removed as you are stitched up again. A drainage tube will be inserted to aid the draining away of fluids from the wound and this will be removed after a few days when everything is drained.

Endoscopic tummy tuck

An endoscopic tummy tuck is the same operation which is carried out in a slightly different procedure, which needs a much smaller abdominal incision. Here a camera and tools are inserted through the small incision to drain the fat. One problem with this method of carrying out a tummy tuck is that it does not allow for the muscles to be tightened, nor the excess skin to b e removed. It is purely a method of fat removal.

Either of these methods of performing a tummy tuck will leave you sore and swollen for a few days, but you should be given painkillers. You can also find yourself numb in that area for as long as six months, but you can help yourself recover more quickly by doing a few light exercises.

All these sound great but it should also be telling you that tummy tuck is major surgery. Further, it is important that the patient discusses not just the advantages and cost but also the side effects and risks of the procedure with the concerned practitioner before deciding to go for it. It’s a big deal and not something you can take lightly or agree to without a lot of thought. You need to think seriously about the advantages and disadvantages of a tummy tuck.

Yoga for weight loss

-YOGASANAM-

I know some people  struggling hard due to over body weight. They put themselves into agony by making severe fasting and vigorous exercises. But all these works without a proper guidance or a systematic approach do any good I think. So if you are looking for a new and effective way of losing weight or tired of sweating for hours on a treadmill without seeing any appreciable results, believe me , there is a way to lose weight in a healthy manner….. YOGA.

I hope some of you may be very familiar with Yoga. Anyway I shall give a very brief description to it, for those who are unfamiliar with the word. “Yoga is a healing system of theory and practice. It is a combination of breathing exercises, physical postures, and meditation that has been practiced for more than 5,000 years and is a form of a spiritual practice in India.”  It’s true that people normally don’t consider yoga for weight loss, but take a moment to think about it. You will invariably find that people who have been practicing yoga regularly are fit and lean, never fat.

Yoga is one of the very effective exercises for weight loss because it works on many different levels at the same time. At the end of the day, yoga aims to bring your body and mind to a natural state, where your entire being functions as one, with full efficiency, and in perfect harmony with the rest of the universe. Let’s take a look at some of the yoga poses for weight loss.

Surya Namaskara: The Surya Namaskara or Sun Salutation is a series of 12 exercises that are performed in a sequential manner. These 12 exercises not only strengthen your body, they also help to boost your metabolism and make your body burn fat faster than ever.

Dwichkrika Asana: The Dwichkrika Asana or Prone Cycling Pose helps to strengthen your abdominal regions and also helps in burning fat. Just a couple of minutes of performing this yoga exercise for weight loss can work wonders on your midsection.

Ardha Hala Asana: The Ardha Hala Asana or Half Plough Pose is one of the best yoga asanas for weight loss. This asana helps to stimulate the digestive system and boosts your metabolism. It is also one of the best exercises to lose that stubborn fat that accumulates on the lower abdomen.

Pawan Mukta Asana: This is also an excellent exercise to stimulate the digestive system and one of the more popular yoga poses for weight loss. This amazing exercise not only tones your midsection, but also helps to dispel any gas that is trapped in the intestines.
