Experts said the Long March rocket debris falling to the release of smoke-free highly toxic (Figure)
fall The rocket debris released from the thick smoke
yesterday, a “Long March rocket debris falling Guizhou still Walled release strong toxic smoke” message, caused concern.
According to the China Aerospace Technology Group news at 18:27 on March 31st, at the Xichang Satellite Launch Center Long March III B “carrier rocket, France Asia-Pacific” communications satellite was successfully sent into the preset orbit. At 18:34 on March 31, a wreckage of crashed yet Village Tujia Township of bees near the Au group. Up to now, causing the villagers’ life is in danger and property damage.
yesterday, the Xichang Satellite Launch Center staff, very detailed evacuation plans for the launch rocket debris fell where little basic difference between theory and real data. In addition, Yumeng Lun, academician of the Chinese Academy of Sciences, China is to study and explore the “recyclable” rocket. Doubts
wreckage matter or rocket boosters
yesterday, the Chinese Academy of Sciences rocket trajectory design experts, the overall design of a research fellow of China Academy of Launch Vehicle Technology Yu Menglun, seen from the photo the wreckage thing is a rocket rocket body, in accordance with the landing position to judge the possibility of rocket boosters relatively large .
he said, “Long March 3-B rocket for a three-stage rocket booster rocket, two booster propellant is toxic, and third-stage rocket thruster liquid hydrogen, liquid oxygen, non-toxic.
“Although most of the propellant is exhausted in flight, but it is possible there are rarely part of the poison residues.” Yu Menglun Academy of Sciences said.
release smoke is a moderately toxic
According to reports, the wreckage of “heaven” acrid yellow smoke, loud noise, and some villagers were scared cry, and some picked up the child and ran. Reported that, tobacco is nitrogen tetroxide is highly toxic.
This message is a Many netizens questioned the falling debris, rocket launchers plans, why not evacuate local people in advance, nitrogen tetroxide residual toxic and other.
As for the smoke produced, Yu Menglun analysis of two possible propellant does not burn and fall to the ground after the volatile smoke; there may have hit the gas generated by the original ground of things.
Yesterday, the relevant person in charge of special fuel supply station of Jiuquan Satellite Launch Center said that the rocket propellant four nitrous oxide residue is not highly toxic, is a moderately toxic poison.
future rocket with wings
the Chinese Academy of Sciences Yu Menglun introduced rocket debris landing safety issues in various countries are facing the problem.
several rocket have fixed the drop area, the general choice of sparsely populated areas, generally the area between the two provinces, the landing area width of 30 km, a length of 50 – 70 km case during launch accident, the Government and local compensation to local residents. “
he said, in order to fundamentally solve the problem, China is also considering the development of how to control the placement of the rocket recyclable rocket fly up, can fly back to the scheduled venue, there is no debris. like ‘aircraft’ as a whole is a kind of ‘winged rocket launch, the wings away; After completion of the task, their wings to fly back. “(reporter Zhong Yuwei)
