<span style="font-size: large;">In the 1930’s, the aviation
industry was in the midst of the major transformation as aircraft manufacturing
was getting modernized. Even though in the first sight at some of the present aircraft, we can say it’s pretty similar like as it looked in the era of
1960’s i.e. it was basically a long metallic tube with some wings on its sides,
but as we get closer to have a clear view at these, planes of today are:<o:p></o:p></span></div>
<div class="MsoNormal">
</div>
<ul>
<li>made of much lighter materials
including composites,</li>
<li>engine is far more efficient
now,</li>
<li>Several interesting
aerodynamic features like winglet has been introduced for the plane to fly more
efficiently.</li>
<li>Even when it comes to the fuel
efficiency, we have seen an improvement of about 70% in last 40 years.</li>
</ul>

<div class="MsoNormal">
But the one thing, I wish to
point out has not changed in last whole century is that the enormous amount of
fuel is being used, which is even adding up to increase the pollution level
with reducing amount of fuels in the nature at a great rate. The world is
turning to governments and business to reduce the human impact on climate
change. But in the recent past we have just got a clue about a new change that
can be seen in upcoming future with the responsibility to revolutionize the
aviation industry yet once again embark on a new journey.<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiP0yjtvjODAsn8yt1ffHz_C07Cb6tkRgvzZkYfTTFlceUXEHhU5pI_atrHck-frCN44wlM4zf2pRdr2VyFnndbPb3DTSktnm9gI1pXwuu1sco7m2vNXnbznWvdKRF28vBgSx5lS6smZQw/s1600/download.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiP0yjtvjODAsn8yt1ffHz_C07Cb6tkRgvzZkYfTTFlceUXEHhU5pI_atrHck-frCN44wlM4zf2pRdr2VyFnndbPb3DTSktnm9gI1pXwuu1sco7m2vNXnbznWvdKRF28vBgSx5lS6smZQw/s1600/download.gif" /></a></div>

Sustainable bio-fuels can be
crucial to providing a cleaner source of fuel to power the world’s fleet of
aircraft and help the billions of people who travel by air each year to lower
the impact of their journey on our planet. Over the last couple of years, we
have seen a major move forward towards the industries interest in the potential
and sustainable bio-fuels for aviation. We have now even seen a whole series of
successful test flights. Infect it has been so successful that we can now
expect at least a small quantity of sustainable bio-fuel to start being used
commercially in the next 3 to 5 years. Hence bio-fuel can be yet another
milestone to be added in the history of aviation industry. Its use has been
gaining popularity over the past few years because of their ability to reduce
the dependence on fossil fuels. As a renewable energy source, bio-fuels is seen
as a viable option for sustaining long-term energy needs if they are managed
efficiently. <o:p></o:p></div>

But after all, it is yet to be
seen that how successful it can be in ever grooming Aviation Industry and how
well it can compete with the era of fossils in the future.<o:p></o:p></div>

IMechE, when I first came across this extraordinary person </span>“Dr. K. P. J. Reddy”<span style="font-weight: normal;">
who was there to talk about his research on the shock waves. Being, an
aerospace graduate I was quite excited about the topic of “Shock Waves” as the
only reason we had to study about it is because of its nature to retard the
airplane or any capsule.</span><br />
Prof. KPJ Reddy<span style="font-weight: normal;"> can be, without any doubt can be credited with the title of </span>“Father of Shock Waves Technology”<span style="font-weight: normal;">, in reference to his works in the field of Shock Waves and Shock
Tube. Thanks to his research, soon we can find a Hypersonic Tunnel in the
laboratories of every aerospace institutions with an Indian brand name </span>“THE
REDDY TUBE”<span style="font-weight: normal;">.</span></h4>

<div class="MsoListParagraphCxSpMiddle" style="text-align: justify;">
</div>
<ul>
<li>A shock wave
is a small area of high pressure and temperature in a gas or liquid that
travels at supersonic speeds. The thickness of the area of high pressure and
temperature is small, as small as one-millionth of a meter, but it is enough to
cause many physical effects when it hits something. Shock waves are produced whenever
energy is released in sudden bursts. In nature, they are produced during
lightning, earthquakes and explosion or in some cases by supersonic aircraft.
Crackers produce weak shock waves.</li>
</ul>
<div>
<br /></div>
Or in physical observance,<br />
<div>
<br /></div>
<ul>
<li>At speeds below that of sound, the air in front of the object
moves away, allowing the object to move forward smoothly. As you keep
increasing the speed — when it surpasses the speed of sound — a ‘disturbance’
is formed in the area around the object. The air in front of the object begins
to change, increasing in pressure, density and temperature, sharply and
abruptly. Such a disturbance is called a ‘shock wave’.”</li>

<li>“The temperature difference is too small to get work done. The efficiency of the engine will be around three per cent at this temperature difference. But due to bacterial activity the efficiency is over 50 per cent,” says Prof. Ajay K. Sood, the corresponding author of the paper from the Department of Physics, IISc.</li>
<li>He further adds "When the bacterial activity is high at 40 degree C the effective temperature is around 2000 degree C; at 17 degree C the bacterial activity is significantly diminished leading to low effective temperature"</li>
<li><b>But still challenges are there</b> :While the tiny heat engine outperformed a conventional engine in efficiency, it is still far less efficient compared with biological motors that operate in our bodies at 100 per cent efficiency even when the temperature remains constant.</li>
