ABOUT AERONATICS

INTRODUCTION


Aeronautics (from Greek ὰήρ āēr which means "air" and ναυτική nautikē which means "navigation, seamanship", i.e. "navigation of the air") is the science involved with the study, design, and manufacture of flight-capable machines, or the techniques of operating aircraft. While the term—literally meaning "sailing the air"—originally referred solely to the science of operating the aircraft, it has since been expanded to include technology, business and other aspects related to aircraft. One of the significant parts in aeronautics is a branch of physical science called aerodynamics, which deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft. Aviation is a term sometimes used interchangeably with aeronautics, although "aeronautics" includes lighter-than-air craft such as airships, while "aviation" does not.





EARLY AERONAUTICS




The first mention of aeronautics in history was in the writings of ancient Egyptians who described the flight of birds. It also finds mention in ancient China where people were flying kites thousands of years ago. The medieval Islamic scientists were not far behind, as they understood the actual mechanism of bird flight. Before scientific investigation of aeronautics started, people started thinking of ways to fly. In a Greek legend, Icarus and his father Daedalus built wings of feathers and wax and flew out of a prison. Icarus flew too close to the sun, the wax melted, and he fell in the sea and drowned. When people started to scientifically study how to fly, people began to understand the basics of air and aerodynamics. Ibn Firnas may have tried to fly in 8th century in Cordoba, Al-Andalus.



Roger Bacon and Leonardo da Vinci were some of the first modern Europeans to study aeronautics. Leonardo studied the flight of birds in developing engineering schematics for some of the earliest flying machines in the late fifteenth century AD. His schematics, however, such as the ornithopter ultimately failed as practical aircraft. The flapping machines that he designed were either too small to generate sufficient lift, or too heavy for a human to operate.



Although the ornithopter continues to be of interest to hobbyists, it was replaced by the glider in the 19th century. Sir George Cayley was one of the most important people in the history of aeronautics. Many consider him the first true scientific aerial investigator and the first person to understand the underlying principles and forces of flight.A pioneer of aeronautical engineering, he is credited as the first person to separate the forces of lift and drag which are in effect on any flight vehicle,



Francesco Lana de Terzi, a 17th Century Jesuit professor of physics and mathematics from Brescia, Lombardy, has been referred to as the Father of Aeronautics. In his work Prodromo dell'Arte Maestra (1670) he proposes a lighter-than-air vessel based on logical deductions from previous work ranging from Archimedes and Euclid to his contemporaries Robert Boyle and Otto von Guericke.



CAREER IN AERONAUTICAL ENGINEERING



Eligibility: 10 + 2 Science; high percentage of marks in Science subjects and qualifying exam (JEE) To be an aeronautical engineer one should be a BE/B.Tech. in aeronautics. The Madras Institute of Technology offers a year postgraduate programme in aeronautical engineering for B.Sc. students. One can also study for M.Tech. and Ph.D. in aeronautics from the Indian Institute of Science, Bangalore.



Those who have passed the Associate membership exam conducted by ASI (Aeronautical Society of India), which is at par with a bachelor's degree in aeronautical engineering, can also become aeronautical engineers. It is possible to take a degree in electronics or physics to work in this field and leave more options open

SAVE THE PLANET

japan’s Environment Ministry is encouraging its citizens to go to bed an hour earlier at night, and get up an hour earlier in the morning. There is much wisdom in the old “early to bed, early to rise” adage. But that’s not what the Environment Ministry has in mind. They see going to bed early as a way to fight global warming.

By saving an hour’s worth of lighting and other electricity use every day, the Morning Challenge campaign says the average household can emit 85 fewer kilograms of carbon per year. Staying up late ensures the whole of mankind’s doom.
It is astounding that the Japanese regulators think that your bedtime is government business. Then again, it may be recalled that this is the same country that has a legally allowable maximum waistline.

* Talk about killjoys. To SAVE THE PLANET from boiling we have been told:
- Not have children;
- Dramatically reduce our prosperity;
- Give up our cats and dogs;
- Sweat in the summer without air
conditioning;
- Freeze in the winter with low heat settings;
- Only eat slow food;
- Become vegan;
- Greatly reduce travel;
- Etc., Etc. Etc.

Now, we are being told that we can save the planet by going to bed early.

The Japanese government has launched a campaign encouraging people to go to bed and get up extra early in order to reduce
household carbon dioxide emissions. The Morning Challenge campaign, unveiled by the Environment Ministry, is based on
the premise that swapping late night electricity for an extra hour of morning sunlight could significantly cut this developed nation’s carbon footprint.

Benjamin Franklin famously said, “Early to bed, early to rise, makes a person healthy, wealthy, and wise,” even calling such a lifestyle a “religious duty.” He never dreamed his bromide would become a prescription for saving the planet.

Wait a minute: Hysterics tell us that to save the planet, the “wealthy” part will have to go. And greater poverty reduces health. It seems to me that if we give into global warming hysteria, that will prove we are not “wise.” But, adopting that lifestyle could still considered a religious duty as part of neo earth worship, so at least the entire quote might not have to be thrown in the dumpster.
