Propulsion-electric

EAA AirVenture ’24 was filled with aircraft debuts, technology advancements, flying and commemorating milestones.

P&WC is working with Maeve on a propulsion system for the European startup's planned hybrid-electric regional turboprop for the 80-seat-class market.

Pratt says the engine developed for the company’s Hybrid-Electric Propulsion (HEP) flight demonstrator has run at full power for the first time.

Heat exchanger for hydrogen engines; conformal LH2 tank; fuel system for LH2; and fuel-cell powertrain tested.

Jekta has selected ZeroAvia to develop a hydrogen-electric, fuel-cell-powered version of its PHA-ZE 100 amphibian, originally designed to rely on batteries.

Collins Aerospace has passed the passed the preliminary design review for the EU's Clean Aviation HECATE project.

Eve Air Mobility, Embraer’s advanced air mobility spinoff, has rolled out the first of six Eve prototypes to support the eVTOL program through developmental flight testing.

Blades of the first ducted fan thruster in the hybrid propulsion system are “spinning as we speak,” GA-ASI President David Alexander said.

In a milestone for electric aircraft, Electric Power Systems (EPS) has submitted the first application for FAA approval of a lithium propulsion battery system.

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.
