This weeks Indian aerospace news as seen from the indianaeronews blog

This week news in Indian aerospace was weak. Thing moved slowly perhaps the record feat of PSLV and the heavy bidding process of IAF global tender was the reason. But then CII began this week when it announced that it has formulated 10-point plan to boost manufacturing. They come out with a 10-point strategic agenda to help the manufacturing sector achieve a 25% share in the country’s GDP by 2020 and the body has identified new initiatives in the area of space, aerospace, advanced engineering and manufacturing. So i guess Indian industry is getting proactive in pursuing its aerospace dreams.

As mentioned earlier,6 aerospace firms from uk, us, sweden etc have bid for the Indian Air Force fighter bids. This will be helpful for India as IAF will get access to cutting-edge radar technology, as permitted by the US government, if it decides to buy Boeing F-18 Superhornets under its global tender for 126 combat aircraft, American space and airborne systems company Raytheon has said. So you see its not only BIG BAZAAR that gives offers, when it comes to being a consumer, even defense companies lure and roll out offers.

Being a propulsion aerospace engineer, i was happy to note when i read GE to manufacture windmills and gas turbines in India. GE India President and CEO Tejpreet S Chopra told PTI, "The company is planning big in three areas infrastructure, energy and aviation, but our main focus is to manufacture windmills and turbines,"

Students of AeSI wake up, 18-year-old Aditya Singh from singapore, has been awarded NASA's top award in an aircraft design competition.The annual student competition, organised by Nasa’s Langley Research Centre, is judged by its team of aeronautic engineers. It drew over 140 research papers from young people in 15 countries. Did anyone of the AeSI students participated?

Rejoices aerospace engineers, in a recent report, the Space Foundation estimated that the value of the world space economy is $250 billion. Yes $250 billion !!! It also adds that so many industries - telecommunications, agriculture, medicine, Earth observation, public health and safety to name a few - have advanced and grown due to development of space technologies. Be proud i say!!

And this is one news we are seeing every week The U.S. aerospace and defense industry is losing an estimated 27,000 employees per year. Good or bad you decide. From Indian perspective i see more role for young and budding indian aerospace engineers!!

If you will note Boeing and TATA didn't figure in indian aero news this week. Instead this time there is a news that all avionics engineers will cherish! Samtel,electronic display panel maker, is venturing into the Indian defence and aerospace market to produce avionics for fighter planes with HAL!

And if you wondered why there were less girls in your aerospace class than the other department. You will find your answer in this story "Dearth of women working in the aerospace sector".

The next news mentioning hindupur caught my attention because i know gururaj is from Hindupur! Caparo Group, one of the world's largest industrial houses promoted by Lord Swraj Paul, is planning to set up an aerospace park at Hindupur in AP.The group is seeking about 1,000 acres. While the government is yet to take a decision, the project is expected to herald a new era in aerospace-related activity.

So this was the round up of the Indian aerospace week as seen from the indianaeronews blog that aim's to follow indian aerospace.

Then there are jobs in Goodrich and Safran at Jobs in Aerospace field!!

How to pass aesi exams ? -from ouraesi

This is the month when OURAeSI was born 6 years ago, so i was just looking at some of the great posts in ouraesi group for the students and i found this gem of a post from the achieves of OURAeSI. It is written by Sunil and i agree with him about the part where he mentions solving lot of problems. Do read his post here which he aptly names as How to pass exams?

I suggest all great AerosocietIans to help there juniors to share
there experiences in this message group. The main idea is to get
some masala to juniors, which helps them in passing Aero.

In this regard, I suggest juniors not only study to pass
examinations, but to understand the phenomenon or theory behind the
problems of the subject. Although this is well known to lot of
persons but still many have problems in passing examinations. I dont
point to there hard work, since most of peoples work hard but the
right approach is missing.

For example: I came across guys during my society, who spend 20 hrs
of there day in solving lot of problems of various books but don't
understand the theory or idea behind the topic. Solving lot of
problems gives you confidence for sure, but sometime it is not
useful since in Exams probability of repeating questions with same
variables is less. This may be only general comment since i don't
know the ongoing pattern.

Also i may not be fully correct and lot of peoples wont agree from
me, but that is the motivation from my side to other peoples to
share there experiences. Which for sure will help juniors pass there
examinations and build a base for there further studies or future
work.

Take care
Sunil

In my last post i talked about "Some do's and don't for the upcoming exams........" that i wrote in ouraesi club. In regards to this Mr. anshuman awasthi had replied with some more suggestions. So to keep the continutiy of the article i am posting his do and don't for the exams here.

Hope this will help you for the upcoming Aeronautical soceity's exams.

Mr. anshuman awasthi wrote

Hello guys,
I do not know how many of us are giving exams.. but what Sukhbinder
said is true to the core but the lack of writing material in
examination hall just shows the apathy of AeSI (on the contrary that
should not deter you in performing well in the exams :-)). well make
sure in advance, as sukhbinder pointed, that there is enough writing
material available.

I do not know whether it can be generalized or not but, at least in my
case, I could never prepare 100% of syllabus for the exams but then i
considered that as a part of the trade.

It is tough to handle AeSI exams we are not sure about the pattern of
the examination papers, about the examiners mentality etc.. What I am
saying be prepared mentally for any casualty viz. some unexpected
question, change of pattern etc.. In my opinion change of pattern is
the most scary thing to happen.

Prepare what you really can prepare. Study 80%-90% but be confident
about that instead of preparing 100%. Go through the old question papers.
You should know answers to all the old question.

Apply the theory of Probability. Do not leave the question which is
been asked frequently. Select any old paper, write down all the
questions on a paper. Then take another paper and keep on ticking the
questions which have been repeated and repeat the process with all the
question papers available. You will see a pattern. Now tick all those
which you have already studied. Hunt down the answers for the
questions which have been repeated every now and then but you haven't
studied.

Good Luck

Some do's and don't for the upcoming exams........

Back in 2002, this time around i was anxious about the upcoming AMAeSI exams and i posted "Some do's and don't for the upcoming exams........" in ouraesi club. I liked the stuff that i wrote back then and i think its relevant even today. So i reposting the email here so people can benefit from it.

Its been a long time since i posted anything here. well , you know exams are knocking so you can guess what i was doing. Then why i am here today u may wonder.

Well last night while i was waiting for my foodwalla to come, i stated thinking of the mistakes that myself and my friends i know did in their exams. And u know what, i got quite a few simple mistakes that have compelled them to study those subjects again! So i thought about posting the do and don't that i have encountered about the exams !! Maybe this will help some of you.

The first thing that comes to mind is the dilemma of my roommate in last exam. He knew all the questions in last years maths exam but he could only attempt 60 marks paper !! Guess why? Time was up. NO the space to write was up !! Yes he consumed all the pages. And to tell u the truth, even I had stopped at the boundary !! So folks when in exams have paper economy in mind !! Its feels really awful to not being able to complete the paper because there's no more page available !! Ask my roommate, he will certify.

Another incident of the last exam was of Hamza, You know he got the highest marks in flights that i know of and he should have completed his section-A last year if he was a bit careful in his last semester's maths exam? Well what he did in his maths exam was that he did different parts of a question at different places. He never read the warning or instruction of doing the same question at the same space and paid the price !! So this year have hamza in mind and do the questions sequentially and attempt all the parts of the question together.

Now comes the major mistake that i did for my last flights exam. I read all my notes, i read all the chapters of the prescribed books and all the theory and solved all the numericals. But guess what i failed Why ? The reason was that i thought i had read everything there to be read and solved all the numericals to be solved but never glanced at the syllabus book and missed 3-4 topics and unfortunately that exam had most questions from those topics. So guys Keep that damn syllabus book before you while you study and see to it that u have studied and covered all the topics.

Another useful advice that i heard once from one of my teacher was to always start with a question u are most comfortable and confidant ! Sounds logically, so why don't you apply it in this exams.

Well that's it and if you have anything to add then u are most welcome.

Please do comment back with all the new advice you can give.

Common mistakes in maths by students!!!

With AeSI exams nearing. I thought of searching the web for some ways in which the web can help us! Guess what ! People who say Internet is a great tool are right. I landed on a particular article that can improve your marks in the maths exams !!

The article, by a maths professor Eric Schechter, mainly discusses the common errors made by students. Its an experience of a math's professor.

The page is very long and i think, like myself, no one of you like reading on a computer when the clock is ticking in the cyber cafe. So i have copied part of the page that i liked the most and presenting it here in a simple structured form.

This particular section discuss about the importance of revision and re-checking. So guys and gals read this article and profit by it.

Going over your work. Unfortunately, most textbooks do not devote a
lot of attention to checking your work, and some teachers also skip
this topic. Perhaps the reason is that there is no well-organized
body of theory on how to check your work. Unfortunately, some
students end up with the impression that it is not necessary to check
your work -- just write it up once, and hope that it's correct. But
that's nonsense. All of us make mistakes sometimes. In any subject,
if you want to do good work, you have to work carefully, and then you
have to check your work. In English, this is called "proofreading";
in computer science, this is called "debugging."

Moreover, in mathematics, checking your work is an important part of
the learning process. Sure, you'll learn what you did wrong when you
get your homework paper back from the grader; but you'll learn the
subject much better if you try very hard to make sure that your
answers are right before you turn in your homework.

It's important to check your work after you do it; but "going over
your work" is not the best way of checking math -- in fact, it's the
worst way (except for not checking your work at all).

I have twisted some words here, in order to make a point. By "going
over your work" I mean reading through the steps that you've just
done, to see if they look right. The drawback of that method is
you're quite likely to make the same mistake again when you read
through your steps! Here is a typical example: After an irreversible
computation, if you forget to check for extraneous roots, then you'll
probably forget again when you "go over your work."

You would be much more likely to catch your error if, instead, you
checked your work by some method that is different from your original
computation. Indeed, with that approach, the only way your error can
go undetected is if you make two different errors that somehow, just
by a remarkable coincidence, manage to cancel each other out -- e.g.,
if you arrive at the same wrong answer by two different incorrect
methods. That happens occasionally, but very seldom.

In many cases, your second method can be easier, because it can make
use of the fact that you already have an answer. This type of
checking is not 100% reliable, but it is very highly reliable, and it
may take very little time and effort.

Here is a simple example. Suppose that we want to solve 3(x–2)+7x=2
(x+1) for x. Here is a correct solution:

3(x–2)+7x=2(x+1)
3x–6+7x=2x+2
3x+7x–2x=2+6
8x=8
x=1

Now, one way to check this work is to plug x=1 into each side of the
original equation, and see if the results come out the same. On the
left side, we have 3(x–2)+7x=3(1–2)+7(1)=3(–1)+7(1)=(–3)+7=4. On the
right side, we have 2(x+1)=2(1+1)=2(2)=4. Those are the same, so the
check works. This computation was by a different method than our
original computation, so it's probably right.

Different kinds of problems require different kinds of checking. For
a few kinds of problems, no other method of checking besides "going
over your work" will suggest itself to you. But for most problems,
some second method of checking will be evident if you think about it
for a moment.

If you absolutely can't think of any other method, here is a last-
resort technique: Put the paper away somewhere. Several hours later
(if you can afford to wait that long), do the same problems over --
by the same method, if need be -- but on a new sheet of paper,
without looking at the first sheet. Then compare the answers. There
is still some chance of making the same error twice, but this method
reduces that chance at least a little. Unfortunately, this technique
doubles the amount of work you have to do, and so you may be
reluctant to employ this technique. Well, that's up to you; it's your
decision. But how badly do you want to master the material and get
the higher grade? How much importance do you attach to the integrity
of your work?

One method that many students use to check their homework is this:
before turning in your paper, compare it with a classmate's paper;
see if the two of you got the same answers. I'll admit that this does
satisfy my criterion: If you got the same answer for a problem, then
that answer is probably right. This approach has both advantages and
disadvantages. One disadvantage is that it may violate your teacher's
rules about homework being an individual effort; perhaps you should
ask your teacher what his or her rules are. Another concern is: how
much do you learn from the comparison of the two answers? If you
discuss the problem with your classmate, you may learn something.
With or without a classmate's involvement, if you think some more
about the different solutions to the problem, you may learn
something.

When you do find that your two answers differ, work very carefully to
determine which one (if either) is correct. Don't hurry through this
crucial last part of the process. You've already demonstrated your
fallibility on this type of problem, so there is extra reason to
doubt the accuracy of any further work on this problem; check your
results several times.

Perhaps the error occurred through mere carelessness, because you
weren't really interested in the work and you were in a hurry to
finish it and put it aside. If so, don't compound that error. You now
must pay for your neglect -- you now must put in even more time to
master the material properly! The problem won't just go away or lose
importance if you ignore it. Mathematics, more than any other
subject, is vertically structured: each concept builds on many
concepts that preceded it. Once you leave a topic unmastered, it will
haunt you repeatedly throughout many of the topics that follow it, in
all of the math courses that follow it.

Also, if discover that you've made an error, try to discover what the
error was. It may be a type of error that you are making with some
frequency. Once you identify it, you may be better able to watch out
for it in the future.

If you are not worn out with this, check out lots of tips offered by this professor here.

Best way to learn Catia and solidworks through self learning

I have hands-on experience with both catia and Solidworks, although during my work in NAL, solidworks was the modeling package that i used on a regular basis while catia i played with just out of curiosity in my free time.

"Catia is vast. Solidworks is user friendly and puts user first" this is the first things that comes to my mind with my experience with both this softwares.

Best way to learn Catia and solidworks is not to begin with an intension of creating a gas turbine assembly or compressor assembly but to begin with something simple say create a glass. I began that way in both this software without any tutor. I did self learning and there are few lessons i would like to share.

1. Before beginning the software yourself, if possible see someone do something in the cad program. He/she might do something complicated. Learning that is not important, just observe what he is doing, soak in the big steps. like from where to start. How much you soak is not important either just seeing someone do something gets you started.

2. Begin with some small and easy thing. i began my solid modeling by drawing glass, dish, bricks, rod.

3. Don't use all the feature at once experiment and during initial tries don't bother about the steps.

4. Once you have dug and drawn something in your cad program, its time to move to the next stage. In this stage you get to the help section of the software. Follow the step by step tutorials provided. If you have done the first 3 steps this one step will enable you to learn more about the tool.

I have seen that jumping directly to this tutorials is not very quick way to grasp the software. If i do the first two stage this tutorials are easy yo follow and i learn and soak more. The previous two actions work like creating the soil soft and when i do the actual tutorial it seems fit in.

This rule can be applied to any software that you decide to learn and master and i have used this technique in learning so many softwares and it always works.
