Propulsion-electric

New aircraft technologies are being overlooked in the 2050 carbon net-zero quest, startups and researchers say.

After the initial funding wave, investors grow leery of unfulfilled promises by startups.

Comparing hydrogen-electric propulsion startups Universal Hydrogen and ZeroAviation reveals companies with quite different business approaches.

American Airlines has signed a conditional purchase agreement with ZeroAvia for 100 hydrogen-electric engines to power regional jets.

Cryo-compressed hydrogen; Nullforming antenna; Contrail mitigation; Condensed battery flies.

GE’s small hybrid core; on-site hydrogen on demand; 3D-printing magnesium; and very-low-orbit space tracker.

The advancement is relevant to both light aviation and the commercial air transport industry.

The near-term UAM market will take time to mature and scale, but regional air mobility enjoys a large addressable market today.

Quebec-based aerial sightseeing operator Bel-Air Aviation has signed a letter of intent to convert three aircraft to all-electric eBeavers.

The companies have signed a cooperation agreement related to the planned certification of the ERA 19-seat hybrid-electric regional airliner.

The company’s engineers are working on the business jet’s architecture, starting with a digital twin.

The aircraft will rival the carrying capacity of the largest civilian helicopters but with lower operating costs and a far superior noise and emissions footprint.

The initial aircraft is planned to launch into a company testing program around the end of this year using only the thermal engine.

The president and CEO of Embraer Executive Jets talks with Aviation Week about the market. Phenom 300 success, supply chain issues and advanced air mobility.

The recently unveiled redesign of Heart Aerospace's ES-30 regional airliner has received criticism from some corners.

The startup says its revamped hybrid system will increase efficiency, but analysts are not as convinced.

The company’s turboelectric airliner concept would reduce fuel usage, operating costs and contrails.

The startup’s EL-2 Goldfinch test pilot outlines his flight experience with the demonstrator.

A hydrogen fuel-cell-powered helicopter is being eyed for zero-emission delivery of manufactured organs for human transplants.

DLR’s climate-friendly designs; High-power aviation fuel cell; and eVTOL hover test facility.

Developers of turbo- and diesel-electric generators offer flexibility.

Certification plans firm up as turbo-compressor and humidifier changes pave the way for the next flight-test phase.

Distributed-propulsion testbed flies; Airbus hydrogen APU demo; uncrewed delivery corridor; another Chinese eVTOL; and Wright’s megawatt-scale electric engine.

The Alia eVTOL makes the first piloted full transitions between vertical and horizontal flight.

Elysian has expanded the advisory board providing input on the design, development and operation of its proposed 90-passenger battery-electric aircraft, the E9X.
