Self-flying aircraft cracked

British scientists build new types of aircraft that can repair cracks themselves, while the US Air Force develops aircraft that can fly more than 6,000 km / h.

"We are inspired by human design. If we do not evolve to withstand the wound, human skin will be as thick as rhino skin. However, when the injured person will bleed, the scalp skin will help immediately. We created materials that function like human skin, " said Professor Duncan Wass, head of the research team at the University of Bristol, England.

According to Sputnik, to make this type of wing, the team put microscopic spheres into synthetic carbon fiber materials used to make the aircraft case.

When a collision or cracking occurs in an aircraft's body or wing, the spheres will release the liquid to patch the damage. However, the time of patching depends on the temperature outside the aircraft, the higher the temperature, the faster the speed of autonomous. This technology is currently only able to repair small cracks on the wings and fuselage.

However, scientists believe this technology will soon be put to use in life with phone screens, sports equipment, or nail polish.

CNN on June 6 reported that the US Air Force is developing an unmanned supersonic aircraft that can fly nearly two kilometers within a second. As planned, this project will be completed in 2023.

In May 2013, the US military finally tested the new supersonic aircraft called X-51Waverider. According to the results, the X-51 has reached a supersonic speed of Mach 5, 5 times the speed of sound, equivalent to 6,115 km / h.

This supersonic technology is a potential "change game " element, changing the nature of the war, US Air Force Major Thomas Masiello said. China and Russia are also developing this technology.

These fighters can be launched from a distance, going so fast that they cannot be located until reaching the target. However, Mica Endsley, head of the US Air Force science department, said there are still some obstacles in developing new navigation systems and materials to build supersonic aircraft.
