Hallelujah: whale fins simulation for manufacturing aircraft wings.Photos & videos
Featuring Sumatran whale in his ability to spin in the form of small circles, despite the hardness of his body length of about twelve metres long and weighed up to about 30,000 kilograms. What is the secret to thicken the water? {And ask them about the village that were present as the sea are on Saturday pressed their whales on Sabbath and day ysbeton not come to them as well as we be or become old them as they prostitute themselves} Sura Al-a'raf: 163.
Researchers say the secret lies in his fins. The leading edge of the fin toothed, where a row of outcrops called drinat. When the Sumatran whale swims quickly in water, aldrinat to increase leverage and reduce the drag force.
He adds that aldrinat make rapid water movement, you pay for the alzavenh flow in turn regularly, even if the whale about water levels in acute angle. If the front edge of the fin smooth as flying wing, to enable the whale from the circulation in the form of small circles upwards towards the surface, because the water will turn in a turbulent swirling behind the flipper will not strengthen to generate lift.
For their part, researchers also want to emulate this whale fins technology for manufacturing aircraft wings to make leaner, safer aircraft in flying farther from the Earth's surface, which reduces maintenance costs and fuel and travel.
Finally, remember the words of the Prophet in the greatness of this marine creature and his good works on land: (good teacher all his forgiveness even whales at sea), (clear) narrated that jaabir (Bazaar) from Aisha and her satisfaction, by Shaykh al-albaani, Sahih Al-Jami ' [1/1083].
