India ensured its place among an elite group of countries making a fighter
jet from scratch when the indigenous multi-role Light Combat Aircraft (LCA)
Tejas got initial operational clearance this week. A key part in this
success was placed by the avionics and flight control systems that were
designed by DRDOs Aeronautical Development Establishment (ADE). PS Krishnan,
distinguished scientist and Director, ADE gives Anirvan Ghosh an inside
view of Tejass journey and the challenges faced along the way
It took the Tejas 1,500 test flights and 23 years of development to get to
this point. Isnt that too long?
You have to see that it started as a thought process in 1983 and there was
no funding at that point. For the next ten years, we firmed up the
requirements and then went into project definition phase. We went to France
and Germany and took their expertise in fixing up the aerodynamic
configuration. Post that we were ready with a firm proposal and the funding
finally started from the second half of 1992. It did take time, but we had
to go through the proper processes.
Then there were the sanctions after Pokhran II. How did that affect the
development of Tejas?
Let me be clear we perhaps got delayed by two years. On the day the
sanctions came into force, our team was in the US offices of our partners
there (Lockheed Martin and BAE Inc.). The team was working on integration of
software with the hardware of the LCA. Suddenly we were asked to leave the
offices, and we were not even allowed to take back the designs we were
working on the systems there, and those were almost ready to be tested. We
had to again develop it from memory, because we werent allowed to copy our
own stuff, which delayed the whole thing.
You are saying that you had to spend some time recovering what you had
already worked on and then build on it?
Exactly. But the sanctions also spurred us on to do better, and to make the
entire fighter aircraft on our own. So in the next few years, we did not
just recover what we had lost back then, but also went some steps ahead and
achieved the expertise that we had tied up with the US companies for. So now
we had what they had but need not rely on them anymore. So ultimately that
did delay us, but also made us stronger.
Was there a point where you were close to losing faith because of the
difficulties that cropped up?
Never really. When we came back from the US, I was called by Dr APJ Abdul
Kalam (who was then the scientific adviser to the Prime Minister). I met him
in his office, along with my boss at that time. He asked me directly, Can
you guys do it? and I replied, Yes. At that time I just thought we could and
didnt think much about the odds. When I did, well of course we were up
against quite a few obstacles.
What was driving you at that point in the face of those odds and how did you
ensure the team stayed motivated?
The thought that alternatives simply wouldnt do. Here we were making the fly
-by-wire system, which would control the aircraft like anautomated system.
Procuring the same from MNCs would have firstly cost more and made us just a
small cog in the wheel. Here we were staring at odds but we also had the
chance to create a new wheel, to invent a new system. This was a challenge
we all rose up to. I told my team at ADE that they had a chance to create
history and be a part of creating something that had never been done before.
They were up for it and responded. In all the 1,500 flights we have had so
far, we never had one single failure. Those included Tejas in its stages as
tech demonstrators, prototype vehicles and limited series production (LSP).
Did you succeed in retaining more of the core team and talent after the pay
commissions's pay hike?
That came later when the team had already done a major portion of the work.
Surely, the pay hikes by the government have allowed us to retain talent.
Before that some people did move out of the project and went in the private
sector where they were better paid. But when I met them later at some event,
they said that they missed working on cutting edge technology and making
something entirely new.
Now you are working on the Regional Transport Aircraft as well as the
unmanned aerial combat vehicle?
Yes, we are making the flight control systems for that project which is
headed by NAL. The flight control system and data link packages of Aura (
unmanned combat aerial vehicle) will be designed and developed jointly by
ADE and Defence Electronic Application Laboratory, Dehradun.
Many private and public agencies worked on the Tejas. They are now
collaborating on the transport aircraft. Does this lead to confusion and
delays?
No, because the parameters are clearly defined. In fact, this happened
smoothly also because of BAE North America. When we were partnering with
them, they had formulated the methodology on how various agencies would work
, and we followed it rigorously.
There are certain things like wake penetration, and others that the IAF
chief said need to be ironed out and the deadline is June. Will you be in a
position to meet the deadline?
Of course, we already have done most of it. There are some control loss
trials, which are essential before it can be operationalised. Those flights
will be completed before June. No modifications are required as I see it,
but then we will have a clearer picture post the tests and then whatever
changes are needed will be implemented. | r********n

LCA的气动是法国人设计的，航电是洛马写的，发动机是买的GE的，雷达是买犹太人的
。阿三就用别人的气动数据画画图，整个壳子，把那些买来的东西装上去，就已经弄了
28年，超支30倍，用了40%以上复合材料还超重1吨多，前几天还发生爆炸过几天就装备
了。
这飞机要想拥有基本作战能力，起码还得5年，要想达到3代机的最低标准，10年都打不
住。这么多年了阿三连大修2代机都不行。中国四十年前最烂的时候，也没这么差劲。

嗯，印度的武器研发水平不是我们的目标，美国的才是。说到底美国，俄罗斯都想用印
度制衡中国。
印度再不行后面还是美国人照着呢。
