According to the British "Daily Mail" January 3, 2012 news, a team of 30 people led by Jason Barnes, a scientist at the University of Idaho, proposed the concept of manufacturing Titan. The aircraft, named Aviatr, will soar over the cloud of Saturn's most mysterious satellite Titan. It is reported that the appearance of Aviatr is similar to the drone used over Afghanistan and weighs 120 kg.
Scientists have always been fascinated by Saturn’s largest satellite, Titan, because it is surrounded by a thick atmosphere. People have long been eager to understand what is hidden beneath their thick clouds. Aviatr's design includes a built-in probe that captures a three-dimensional image of the Titan's surface to help scientists build a geological picture of the planet. By design, Aviatr will end its mission and will dive down the Titan surface and try to land on its surface sand dunes.
Scientists believe that Titan is the only extraterrestrial object that can support aircraft heavier than air. Its gravitational effect is relatively small, but it has a thick atmosphere, which means that aircraft that are heavier than air, such as Aviatr, can stay in the air for longer.
Unlike traditional methods of detecting Titan – using balloons, Aviatr will allow scientists to precisely control their height and create a library of three-dimensional images that captures Titan’s surface and climate.
It is reported that Aviatr will be more nimble than a balloon, and will use a helium generator to keep it in the Titan's white face and maximize effective shooting time. In addition, whenever Aviatr transmits an image to Earth, it will automatically switch to coast mode to save energy. Like the Earth’s aircraft, Aviatr also has a “safety mode.†When an emergency occurs, such as a communication failure, it will ensure that Aviatr stays in Titan’s atmosphere and ensures that it will not be harmed.
The new solar-powered aircraft looks exactly like the U.S. unmanned aircraft used in Afghanistan.
Titan
Titan is the largest of the 31 satellites of Saturn. It was discovered by the Dutch physicist, astronomer and mathematician Christian Huygens on March 25, 1655. It was also discovered in the solar system by the Jupiter Galileo satellite. The first satellite discovered later. Because it is the only satellite in the solar system with a strong atmosphere, it is considered a time machine that can help us understand the initial conditions of the earth and reveal the mysteries of how earth creatures were born.
Titan is 12,181,030 kilometers from Saturn, 5,150 kilometers in diameter, 50% larger than the Moon and even larger than Mercury, so it was crowned as the titan of the ancient Greek god Titan. Titan's surface temperature is approximately -178 to 178 degrees Celsius, with a very thick atmosphere, and a layer of mist shrouding the surface 200 kilometers above.
Astronomers believe that there are numerous lakes formed of liquid methane and ethane on Titan. The satellite is colder than Antarctica. Scientists say that although Titan is colder, the wind, rain, and tectonic processes on it make it the most similar object in the solar system to Earth. Although the satellite's average surface temperature of minus 292 degrees Fahrenheit (minus 180 degrees Celsius) keeps the water solid all the time, it has liquid methane and ethane present on its surface, which can provide a habitat for life.
40 years after solar-powered aircraft is expected to be used by civilians
Solar aircraft is made of solar radiation
In order to promote the energy of the aircraft, the power plant consists of solar cells, DC motors, speed reducers, propellers and control devices. Due to the small energy density of solar radiation, in order to obtain sufficient energy, solar aircraft must have a large surface area for sunlight.
In the 1970s, with the emergence of solar cells with reasonable costs, solar-powered aircraft came into being, but at the time only micro-machines were available. At present, solar-powered aircraft are still in experimental research. Solar-powered aircraft can be called "pure green flight." IATA hopes to achieve zero carbon emissions from aircraft by 2050. It is envisaged that after solving the problem of the efficiency of light energy absorption, it is expected that all-solar aircraft carrying 300 passengers within 40 years will be officially put into operation. The U.S. military plans to use solar unmanned aerial vehicles as reconnaissance and communication tools, while the private and scientific communities have launched a series of development plans to make these aircraft perform earth observation missions.
