Boeing to build braced-wing airliner, shooting for 30% efficiency gain

With a US$425-million cash injection from NASA, Boeing will build and test a full-sized airliner based on its transonic truss-braced wing (TTBW) concept, using long, thin, strut-braced wings to add lift, reduce drag, and burn an impressive 30% less fuel.

Toroidal propellers: A noise-killing game changer in air and water

These strangely-shaped twisted-toroid propellers look like a revolutionary (sorry) advance for the aviation and marine sectors. Radically quieter than traditional propellers in both air and water, they're also showing some huge efficiency gains.

ASKA debuts fully functional A5 flying car prototype at CES

Looking like a cross between a helicopter and a fixed-wing airplane, ASKA’s full-scale A5 eVTOL prototype is currently capable of both driving and flying. It stole the show at CES 2023, earlier this month.

AAC to develop a unique free-swinging tilt-wing UAV for NASA

NASA has contracted Virginia's Advanced Air Company to design and build a prototype of a new type of transition-capable eVTOL drone – a tilt-wing concept that uses aerodynamic forces instead of actuators to tilt the wings and propulsion systems.

Awful video celebrates Archer’s first full-transition eVTOL flight

There are very few full-size aircraft capable of transitioning between vertical takeoff and landing and wing-borne horizontal cruise flight, so it's a big deal when a company manages the feat, as Archer has now claimed. But the video is a shocker.
