According to foreign media reports, researchers at Princeton University in the United States have recently created a magical flying carpet. Although it cannot be carried at present, it may be used in the future exploration of Mars. L. Mahadevan, a mathematician at Harvard University in the United States, launched a plastic sheet in an experiment in 2007. His research shows that the sheet can vibrate forward quickly in wave motion, just like a beam of light swimming near the bottom of the sea, or staying in the air. Mahadevwan did not create a flying blanket. He just continued to analyze how wet paper curled. But in 2008, Noah Jafferis, a graduate student at Princeton University, saw Mahathirvan’s thesis and turned his ideas into reality. But what Jaffris made is not exactly a flying carpet. It is more like a 4-inch (about 10 cm) long and 1.5-inch (4 cm) wide plastic transport vehicle, but it is still the first A tool that advances through the air. Jaffris's carpet is made of two plastic sheets that are glued together and divided into four sections. When a voltage is applied, part of the surface shrinks while the other part expands, causing the sheet to bend into a shape of moving water waves. Waves push air trapped between the board and the ground. When the board is pushed in the opposite direction, it stays in the air as long as the board advances. Jaffris said: "We use integrated piezo actuators and sensors to demonstrate that plastic sheets can be suspended on a flat air surface and generate thrust control lateral motion. This principle confirms the construction of a horizontal surface. 'The basis of the physical model of the 'flying carpet'." Now, Juffries's carpet is connected to an external battery through a 10 cm long wire to obtain electricity, which severely limits its flight distance. Jaffris wants to install power on the carpet. He said: "We need a 50-foot (about 15 meters) wide surface in order to carry people." He predicted that the technology can be applied to the future of Mars surface exploration tasks.
