According to foreign media reports, the sail-shaped spacecraft has a wide range of applications. From the appearance point of view, it is a huge film, but this film is not ordinary. If it is a solar sail ship, then it is a kind of film mirror, through the solar wind. The radiation pressure pushes the spacecraft forward.
The solar sail ship is not the same as a traditional spacecraft. Its acceleration is relatively slow. It takes a long time to reach a certain speed, but the maximum speed is very amazing. Scientists believe that the solar sail ship has the potential to fly out of the solar system, and now we The solar sail technology mastered can be fully used for the interplanetary exploration flight. Both Japan and the United States are developing solar sail ships.
The sail-shaped spacecraft has great potential for application as a spacecraft for orbital clearance and interplanetary exploration of spacecraft.
The European Space Agency has created a "tissue sail" spacecraft.
Another important use of the sail-shaped spacecraft is to create orbital cleaning robots. Scientists of the European Space Agency are developing a “tissue sail†spacecraft, an ultra-lightweight material that can be used to clean trash on rails. For example, satellites that have failed, space debris generated when the rocket launches, etc. When satellites and other spacecraft complete their missions, they face a situation of being abandoned. Uncontrolled satellites can pose threats to other spacecraft. Some spacecraft have not entered the atmosphere for burning for more than a decade in orbit, such as In 2005, the rocket wreckage that the United States launched 31 years ago collided with the rocket wreckage that China launched five years ago, at an altitude of about 885 kilometers above the ground.
The European Space Agency’s “Lens Sails†spacecraft is very small, only 15x15x25 cm, and weighs only about 2 kg. When it enters orbit, it can expand to 5×5 meters, enough to drag down satellites with a mass of 700 kilograms. The extremely lightweight carbon fiber used in the material was developed by researchers at the Surrey Space Center. It is mainly used for garbage removal on low-Earth orbits. The orbits are cleaned and cleared at about 700 km altitude. The high-satellite, "Shinyaila" spacecraft can also use solar pressure to propel, without using a massive engine, using solar sail technology to lower the orbit.
The “Ship Sails†spacecraft has been undergoing rigorous testing, including thermal environment, vibration and vacuum tests. The research team hopes to conduct an on-orbit test in 2014 and enter the track through a piggy back launcher once the “tissue When the "sailing" spacecraft enters a predetermined orbit, deployment tests can be conducted and the efficiency of solar sail propulsion can be demonstrated in about two to three weeks.
The “Ship Sails†spacecraft captures spacecraft that have failed in orbit through large sail-shaped structures and uses solar sails to propel the spacecraft out of orbit and into the atmosphere to burn. As long as it takes about 25 years to clear space debris on the rails, The University of Surrey professor Vaios Lappas believes that the "Shiny Sails" spacecraft has now been designed and manufactured. The technical staff of the European Space Agency also believes that the "Chiff Sails" spacecraft has extremely strong commercial value. Its technology involves cleaning up space. The application of rubbish and solar sail power has broad prospects.
