AIRCRAFT Japanese paper is expected to penetrate the Earth's atmosphere from space luar.Namun, difficulties team predict the location of aircraft landing paper.
Japan's space agency JAXA (Japan Aerospace Exploration Agency) in cooperation with the experts of paper folding art of Origami Airplane Association Japan (JOAA) to design a paper airplane to be launched from the international space station ISS to Earth. This is not a project mainmain.
JAXA experiment was to examine the design of the space shuttle future more secure and efficient. JAXA had already done the simulation in a hypersonic wind tunnel at the laboratories of the University of Tokyo. As a result, a paper airplane that has a length of about three inches wide and about five centimeters was not destroyed when shot with a speed seven times the speed of sound (Mach 7).
And at such a high speed, the aircraft must withstand heat up to 200 degrees Celsius.Kondisi in laboratory conditions similar to those experienced when flying a paper airplane from space through Earth's atmosphere. "JAXA has budgeted 90 million yen (approximately Rp 8, 1 billion) to finance research paper airplane for three years," said JAXA scientists Hidehiro Akashi.
Study leader Professor of Aeronautics and Astronautics the University of Tokyo said Shinji Suzuki, a paper airplane-making idea is actually already appeared ten years ago. "At first, we considered crazy for wanting to make a spaceship made of paper.
However, we proved our idea is not at all silly as a paper airplane could withstand the heat when it penetrates the atmosphere, "said Suzuki. Suzuki explained, paper airplane made of paper made from sugar cane fiber that resists heat, wind, and air.Kertas cane fiber is then sprayed with a special coating liquid and then folded like the shape of the U.S. space shuttle.
The folded paper airplane by Chief JOAA Takuo Toda. Art of paper folding experts spent 18 months to make the most appropriate design. That paper airplane folded from a piece of paper with no cuts and perekat.Toda've tried hundreds of designs before getting the final version is ready to fly.
Suzuki and Toda argued, paper airplane now has a good aerodynamic design to reduce air friction when penetrating the Earth's atmosphere, which is one of the most critical stages in the mission shuttle flights. Without proper aerodynamics and heat shield formidable barrier, the shuttle will burn out when it penetrates the Earth's atmosphere from outer space.
Suzuki confirms, paper airplane pilot will pave the way creating an extra lightweight spacecraft used to study the upper atmosphere. Paper airplane is planned to be launched from the ISS when the U.S. space agency JAXA and NASA have completed installation of Japan's Kibo space laboratory at the ISS, ie in 2010.
"The biggest problem today is landing. Because the plane is so light, the plane would have blown away the wind when it enters the troposphere, "said Suzuki. Suzuki explained, the research team had to consider planting a small transmitter on the paper airplane to facilitate tracking. However, it has increased the weight of the transmitter plane that makes the aircraft difficult to penetrate the Earth's atmosphere.
