The UK-based battery technology specialist Oxis Energy has gone into administration after failing to secure fresh investment despite breakthroughs in areas such as lithium-sulfur batteries.

An eVTOL unmanned aircraft developed by students from the University of Michigan won the top prize in this year's Design-Build-Vertical-Flight competition.

Lima NY, which operates charter flights as part of the Blade Urban Air Mobility network, is to convert its Cessna Caravan seaplanes to electric propulsion under an agreement with electric motor developer MagniX.

Skyports is teaming with several local organizations on the west coast of Ireland to develop a vertiport at Shannon Airport to support eVTOL aircraft passenger and cargo services.

The hybrid-electric, fixed-wing model is projected to have range of up to 187 miles, but will carry only two passengers, like the existing EH216 aircraft.

Kelekona says it can adapt the blended wing, or lifting body, airframe concept to carry up to 40 passengers on flights between cities that are 350 miles apart.

Merlin Labs is developing what its calls a "drop-in autonomy kit" that can convert aircraft such as the twin-engine King Air for remotely piloted operations.

Artificial intelligence specialist Daedalean and EASA published the findings from their latest Concepts for Design Assurance for Neural Networks study, which supports the European aviation safety agency's proposed roadmap for implementing the technology.

The UK company is almost ready to start structural engineering work for the prototype of an 18-passenger aircraft that it aims to begin flight testing in 2024.

Japanese automotive group Denso produces a wide variety of systems and components for road vehicles and has experience with mass production that could prove valuable in the urban air mobility sector.

The Slovenian company's engineering team is evaluating three variations on its design for a 20-seat regional airliner that would be able to fly up to four 350-km trips in succession.

The UK-based eVTOL aircraft developer has appointed Eduardo Dominguez Puerta as its chief commercial officer to help it bring the five-seat VA-X4 model to market in 2024.

Ahead of the July 7 start of its lawsuit against Archer alleging theft of trade secrets and intellectual property, Wisk's attorneys have requested a preliminary injunction against its rival.

Luxembourg-based Luxaviation has 10 European air operator certificates and manages a fleet of more than 100 business jets and helicopters.

The UK-based company, which develops ground infrastructure including vertiports and also is involved in commercial drone operations, views Japan as a potential early adopter of eVTOL aircraft.

Wisk's lawyers will argue that rival eVTOL developer Archer couldn't possibly have designed its new five-seat model so quickly without stealing intellectual property from its rival. Archer says the lawsuit is baseless.

Thales says it is close to finalizing the design of an aircraft collision avoidance system for smaller unmanned air systems, and that this could be a template for larger autonomous aircraft.

The European aviation safety agency assessed the perspectives of 4,000 citizens in six European metropolitan areas. It found that more than four-fifths of respondents had a "positive initial attitude" to the new aviation sector.

The additional capital will support the expansion of Beta Technologies' engineering and production resources as it works to bring the Alia 250 eVTOL aircraft to market by 2024.

The German company intends to directly challenge rival like Joby, Archer and Lilium with a four-seat lift-and-push eVTOL model with a range of 60 miles.
