Malaysian Prime Minister Najib Tun Razak today announced previously found on the island of Reunion is determined from the wreckage of Malaysia Airlines MH370 aircraft. Let's go back to the details of MH370 to see this being a wing, we can find out what information.
The wreckage of the aircraft which one?
2 m long piece of debris is likely to be part of the wing, attached to some shellfish, should be able to determine, wreckage floating in the sea for a long time.
Boeing 777 wing design in improving the 757 and 767, based on increasing the length and thickness of the wing, wingspan increased to 60.9 meters, and optimize the performance of the wing. In the aircraft wing, with a large number of aerodynamic surfaces including a leading edge flaps, trailing edge flaps, speed brakes and other non-movable airfoil. Among these, the speed brakes and leading edge flaps are associated with this piece of wreckage of a completely different structure, and the aircraft wreckage and trailing edge flaps actually very similar.
Trailing edge flaps as a modern wing airfoil-shaped edge portions of the movable means, the basic role is to increase lift during flight. Usually close to the trailing edge flaps on the lower surface of the wing. In use, the flaps along the lower wing surface mounting rails back, while under bias.
From the wreckage point of view, despite the emergence of the edge component wear, but the member remains substantially complete, has been missing only on one side and a thinner tail end, and from the thickness of the airfoil, the wreckage of the aircraft is most likely to be located middle wing. After an engine vents flaperons, rather than the inside of the double-slit flaps or retreat outside retreat slotted flaps.
How to drift to Reunion?
Since this piece of wreckage was found in East Africa Reunion near Madagascar, and the parties had concentrated search throughout the South China Sea from Australia to western waters, including more than 5,000 kilometers away from both, the previous forecast, due to the aircraft carrying fuel limited, Australia's western waters is considered a possible aircraft crashed into the sea after the place had been flying south, but now suspected of wreckage in the Indian Ocean west of the airplane flight can not, and the emergence of this phenomenon is curious if it does occur, the only reason why one, that is ocean currents.
In the Indian Ocean, located in the southern Indian Ocean between Australia and the western waters of the sea of Western Australia have cold, these two sea currents will be delivered to the North Sea south of the equator, and then driven westward sea to the east of Madagascar. Seawater flow in this region will be close to a distance of 8000 km. Due to the cold of Western Australia slow time of day advance was less than 20 kilometers south of the equator warm faster, one day forward 20-80 kilometers.
MH370 missing from the wreckage was found a few days ago, after a year and a total of four months, and about 480 days, and the sea currents in the speed of roughly similar.
This is also verified from the side initially concerned speculate on MH370 waters falling roughly accurate. But even so, the existing detection technology for humanity, the waters of the Indian Ocean crash is still too great, in addition to people searching the waters of Western Australia at a later time MH370 lost contact for several days, a variety of factors such delays can not be found the wreckage has become a relatively reasonable thing.
How aircraft into the sea?
Even if found wreckage identified as belonging to MH370, it is also impossible to speculate how the aircraft fall into the sea. But from the wreckage to see this, it is located in the rear of the engine, but only traces of prolonged immersion seawater, there is no significant ablation effect, which suggests the possibility of a fire engine aircraft in the air is unlikely. Coupled with the first time the relevant sea search found no wreckage after the plane lost contact with the aircraft, the aircraft lost contact because of the terrorist attacks suffered sudden explosion of argument is clearly untenable.
If you exclude the aircraft burst into flames such accidents, plus the plane crashed near the point of maximum range Boeing 777, MH370 then the most likely cause of the crash, the plane should still be after a long flight, the fuel runs out into the sea. Large aircraft ditching present beset with difficulties, depleted fuel unpowered glider landing is almost no hope of success.
In this case, the aircraft will be less good gesture or landing crashed into the sea, as part of the wing trailing edge flap assembly also heavy impact disengaged. From the current situation, the main fuselage and wings may have been severely deformed later sank, but can drift out of small parts is not much. It further ruled out the possibility of the disintegration of the air, because in this case, there is usually a large number of small fragments scattered on the sea, the probability of discovery is much greater.
Only be determined after the latest news, Boeing has confirmed that the serial number on the wreckage is not included in the wing production number, which may be in the MAS maintenance-related parts to add their own number, need to further consult MAS aircraft related information.
Although the parties have put before a "This is MH370" posture, but in more wreckage was found and identified, the truth about MH370 mystery remains heavy.
