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, but will also be able to reduce emissions by at least 50%. The aircraft is interesting not only as civilian transportation. Its design can be adapted as a cargo and jetliner. It can also be converted into a tanker.
In May 2023, JetZero announced its plans to build and certify the aircraft and received a $4,500,000 grant. Shortly thereafter, the company entered into a $235,000,000 contract with a U.S. agency that will provide funding for the next 4 years. The full-scale launch of the prototype is scheduled for early 2027. If everything goes smoothly, commercial operation of the new airplane will start in 2030.

World’s first rocket-powered aircraft can take off in September
German startup POLARIS Spaceplanes announced the launch of the world's first rocket-powered airplane Aerospike.
The new demonstrator is 49.99 meters long and has a wing area 30% larger than its predecessor, the MIRA model. The Aerospike differs from traditional nozzles and directs the exhaust down the sides of the center spike, allowing it to adapt to different altitudes and speeds, ensuring cons

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
