Shape-shifting airplanes could become real thanks to a new alloy
Scientists from the National Institute of Materials Science in Japan have created a highly elastic alloy of titanium and nickel. It can stretch up to 20 times.
The researchers developed a three-step procedure that allows the alloy to exhibit its unique properties at different temperatures. In the process, it was first deformed by more than 50%, then heated to 300°C and elongated again by 12%. As a result, the material was able to withstand 18,000 times the normal atmospheric pressure. The new alloy combines the strength of steel with the elasticity of rubber.
The development demonstrates its characteristics in a wide range of temperatures - from -80 to 80°C. According to the authors of the project, the alloy behaves more like glass than metal due to the presence of areas that support deformation.
Its production method is simple and can be easily replicated in other laboratories. It is also suitable for large-scale industrial implementation.

Project of a unique hydrogen aircraft with a mixed wing has been approved
A mixed wing aircraft has been developed by air carrier EasyJet in cooperation with startup JetZero.
The concept, according to the developers, allows for a significant increase in lift and a reduction in the wing area required for flight. It also eliminates the need for a tail wing, which reduces drag and structural weight.
The new hydrogen fueled aircraft will not only feature a blended wing, b
