هواپیمایی که ناجی زمین می‌شود!

See SWNS story SWNAxplane. NASA have unveiled the plane they hope will save the Earth. They aim for the experimental aircraft to help reach net zero aviation emissions goal by 2050. Working with NASA as part of a $725 million agreement, Boeing will build, test, and fly a full-scale demonstrator aircraft with extra-long, thin wings stabilised by diagonal struts, known as a Transonic Truss-Braced Wing concept. It is hoped the new X-plane will inform a potential new generation of more sustainable single-aisle aircraft – the workhorse of passenger airlines around the world.
