Japan's Tokyo Institute of Technology scientists developed the micro-power laser foil aircraft, recently successfully conducted its first test flight. According to the latest edition of "Nature" magazine reported that the Japanese researchers design of the plane only a few centimetres long, made entirely from aluminum foil. The researchers used a laser fired by Taiwanese plane "paper" aircraft, flight speed of 1.4 m / sec. The researchers hope that future aircraft fleet through the establishment of such a group to monitor climate change, or the volcanic eruption of the situation. Japanese researchers of the design inspiration comes from the United States engineers Asekante Luo Weici. In 1972 he made a point of view, to be a bouquet of laser focus on the surface of aircraft fuel material, to produce a flow, like the general principle of the jet engine, will push the aircraft forward. 1997, the U.S. Air Force Research Laboratory to use high-intensity far-infrared laser, so that a successful Chatuo size of aluminum aircraft in the air forward a few hundred feet (1 ft = 0.3048 meters). The Japanese researchers for the design of aircraft fuel surface layer acrylic polymer or a few dripping. The researchers said that this "paper" aircraft in the laser beam can be focused within the framework of the launch, the surface layer of acrylic polymer fuel sufficient to provide aircraft to take off most of the required impetus. As the process of aircraft in flight could not get a second use of laser power, the aircraft can be used within the storage device to replace the water droplets, this way we can ensure that the aircraft still have enough fuel to power sustained flight. Researchers said the next step, they will use lasers to control aircraft movements, for example, Doula debris on the wing. At the same time, they also plan to use the alloy to create the wings, so that in the wings to change shape when heated.
