Atlanta company Hermeus has its sights set on Mach 4 next year, to beat the Mach 3.3 benchmark set by the SR-71 Blackbird way back in 1976. Watch its Chimera hybrid engine nailing the switch between low-speed turbojet mode and hypersonic ramjet mode.

Britain's Arc Aero Systems, formerly Samad Aerospace, has put forth its vision for a "cost-effective, low-carbon solution to intercity travel." The hybrid Linx P9 promises to beat comparably sized helicopters on range, speed and operating cost.

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.

DARPA has awarded Aurora Flight Sciences a phase 2 contract for its CRANE (Control of Revolutionary Aircraft with Novel Effectors) program, following wind tunnel testing of a small-scale X-plane that uses compressed air bursts instead of control surfaces.

ZeroAvia's 19-seat Dornier 228 has taken its first test flight in the UK. It's a testbed for the company's clean aviation technology, using a zero-emissions hydrogen-electric powertrain that's slated for certification and commercial flights by 2025.

Like bladeless Dyson fans on steroids, Jetoptera's unique aircraft propulsion systems look like pure sci-fi. But they're beginning to demonstrate some fascinating capabilities in testing, and the next step will be a super-fast VTOL aircraft design.

The means of carriage needn't be the means of locomotion, says Node Air, and logistics for passengers and cargo will work better with detachable pods that can connect to air or ground vehicles as needed. It's teamed up with JetX to pursue its vision.

The Cavorite X5 is a fascinating eVTOL air taxi design, capable of splitting its wing covers apart to reveal its vertical lift fans, or closing them for high-speed, long-range cruise flight. Horizon has now started flight testing its prototype.

As the world's major powers continue their never-ending arms race into the hypersonic age, the US Air Force has set Leidos to work on a large air-breathing hypersonic drone capable of handling intelligence, recon, surveillance and strike missions.

Rolls-Royce says it's finished building the first demonstrator for its massive UltraFan engine, which will eventually hit the skies in airliners to be developed in the 2030s. Testing begins soon, with expectations of a 25% leap in efficiency.

Although gyroplanes were once bare-bones open-cockpit contraptions, we're seeing an increasing number of more deluxe, fully enclosed models. The Argon GTL 915 iS is one of the latest – and certainly one of the sharpest-looking – to hit the market.

Hot on the heels of Lilium's Phoenix 2 demonstrator, Israel's Air has released video footage of its two-seat personal eVTOL prototype transitioning to cruise flight, marking the start of the company's bid for FAA certification.

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.

Covering short distances with zero emissions is the modus operandi for electric aviation startups like Eviation, whose Alice plane has caught the eye of Air New Zealand as the carrier works to reduce its carbon footprint.

An era of aviation history came to an end after 54 years. On Tuesday the last 747 Jumbo Jet rolled off the production line at Boeing's Everett, Washington, facility. Built for Atlas Air, the 747-8 freighter is the last of 1,574 Jumbos built.
