The Beijing News (Reporter Zhong Yuwei) last month, the 40th Geneva International Exhibition of Inventions, Beijing Normal University High School high school girls to woo students with "manned aircraft parachute landing Problems of the" Silver Award project invention.
Plane loaded parachute, feasible? Yesterday, the Beijing Normal University High School lab, Gao Yu took "dressed seven parachute,http://www.cosmeticlive.com/forum/profile/soiblko4q1," the model aircraft, about the mystery.
Gao Yu two years time, collect material, to experiment, to write a 20,000-word thesis, covering crash accident statistics, landing treatment options, their new landing programs, projects and promotion of the advantages of recommendations,http://84835.vhost90.cloudvhost.net/news/html/?863114.html, as well as a detailed map that and digital formula.
Referring to the Shenzhou spacecraft parachute cord
"I later research found difficulty landing aircraft is the speed, weight and balance when landing." Gao Yu wondering, can not use multi-way umbrella of "landing" aircraft pulled. After she passed several "landing" experiment,Louboutin à Bout Ouvert, it concluded: as long as the umbrella area enough, layers enough to maintain the shape of the umbrella, you can play bearing the weight of the aircraft.
Select parachute cord "material", the Gao Yu found that a new type of composite carbon fiber material, the intensity with which the rope is made of steel several times, very light; and in the light of the Shenzhou spacecraft umbrella rope,http://www.lmkzx.com/wxy/forum.php?mod=viewthread&tid=132377, parachute time the spacecraft's speed, measure the thickness of the straps is that you can gain.
Consider reducing aircraft modification costs
Gao Yu aircraft made an emergency landing three solutions: from "computer-controlled multi-balanced parachute", "The plane was landing gear landing new buffer plus air damper cross scissor shaped institutions" and "automatic parachute rope rope device. " It is reported that three invention has been patented and approved. Gao Yu summarizes the six advantages, including the parachute does not take up space inside the aircraft effective, low cost, the operation is not complicated, can be transplanted in all aviation, spacecraft safety landing.
"After her thesis written, was not the end, but then I found a professor at Nanjing University of Aeronautics and Astronautics, also looking for expert guidance SPACE Institute."
There are two universities of science and engineering, to the high school student enrollment thrown an olive branch.
Gao Yu instructor is Zhao Xin Beijing Normal University High School, she expressed her concerns, currently the school has a lot of good ideas, but the results of science and technology into the bottleneck of technology projects.
■ experts say
"The plane was too heavy can not be used parafoil"
Last night,http://www.loveziyan.com/forum.php?mod=viewthread&tid=1532839, the reporter Gao Yu student papers will be forwarded to the spacecraft Shenzhou spacecraft emergency survival expert system. Experts first affirmed Gao Yu dare to think boldly and innovation.
"Scrutiny from the scientific point of view, still a little problem." The expert paper gives some suggestions parachute process is not perfect, at the same time, you can not open the main parachute immediately, also need guidance umbrella parachute.
Aerospace experts, the current recovery parachute aircraft experience in foreign countries have been successful, but the recovery is unmanned aerial vehicles, lighter; if a great weight of the aircraft, you can not use "parafoil" aircraft weight is fixed, After adding a parachute will inevitably lead to reduced passenger.
Yesterday, Professor Huang Jun Beijing University of Aeronautics and Astronautics Research aircraft conceptual design,http://jj1314.com/forum.php?mod=viewthread&tid=516242, said Gao Yu envisaged is theoretically feasible; mounted parachute scholars also have been considered,Louboutin Baskets Femme, but the cost estimate is not the best. Huang Jun also said that Gao Yu's idea can be applied to senior public (commercial) service machine. Beijing News reporter Zhong Yuwei
