AERO-SHARK TECHNOLOGY
Whenever we talk about sharks, we talk how superior they are. Superior in terms of speed, evolution and attack techniques. But what if they are something more than that.
What if they have the answer to the question aviation is desperately looking for? Whatif they holds the secret that will transform the way we fly? And like sharks, whatif ocean has some other treasure waiting to be discovered?
let’s try to find out…
Shark’s hidden gift…
Shark’s do posses many interesting features that are exceptional in it’s own way, but the particular quality we are more concerned with is it’s skin, so let’s take a look at it in details…
Unlike other aquatic creatures, shark’s skin feels like sandpaper, and I’m not joking, you can literally cut your skin with it.
Biologically it is made up of tiny teeth like structure called “placoid” scales AKA “DERMAL DENTICLES”.
They are placed facing towards the tail that helps reduce friction from surrounding water when sharks swim, enabling them to swim faster through water.
Below is a video showing how these “Denticles” actually interact with water.(*watch in 360 or above for best experience)
Aero Shark programme
Whether in case of swimming or antibacterial surface for homes and hospitals, these denticles proved far more reliable than expected.
In fact in 2000 Olympics, much of the medals in swimming are won by participants wearing swimsuits offered by SPEEDO having paint that mimics sharkskin.
After witnessing what this marvelous piece of technology can do, LUFTHANSA in coordination with BSAF (leading manufacturer in chemicals and coating) have planned to introduce this engineering marvel in aviation with its B777-freighter fleet.
They have developed a film that will mimics the skin of sharks, optimizing airflow and reduce drag.
These films will have small protrusions called “riblets” of about 50 mm high in size, produced in small patches for easy application.
According to the company
“These riblets if applied in specific manner & aligned with the airflow will produce efficiency gain and will improve lift if attached on the wings”
Advantage
According to Lufthansa technik these technology if used for the airframe surface will produce:
Fuel saving
Easy application
no additional downtime
Can be installed on any aircraft
Even SWISS AIRLINES with the help of Lufthansa technik has launched it’s first passenger flight equipped with “AERO SHARK TECHNOLOGY” on Oct 14 at 13:39 local time. And hence became the first airliner to launch this technology
CONCLUSION
There is a huge battle going on in the aviation industry, a battle to achieve flying with increased efficiency and reduced CO2 emission, so that we could transport people and save our mother nature at the same time.
And in times like this where we need all hands on the deck, such innovation will come as a great relief.
Well, what technological advantage and challenges will it brings only the time will tell. BUT till then “lets just hope for the best”.
