Airbus combines electric aircraft designs for air mobility initiative
Airbus is combining its two short-range electric aircraft designs – the rotor-based Vahana and the fixed-wing CityAirbus NextGen concept – for a collaboration in Germany (writes Nick Flaherty). “The first is for a long hover times, for example for rescue operations, while the Vahana is for longer flights, for example from Nuremberg to Munich,” says […]
Meeting the challenges of developing e-VTOL air taxis
AutoFlight’s Prosperity I, a Chinese-designed e-VTOL air taxi sized to accommodate a pilot and three passengers, is intended to meet the rigorous safety standards that apply to transport-category aircraft including the largest airliners, and the company is aiming for certification and service entry in 2025 (writes Peter Donaldson). Invited by electric aviation pioneer and AutoFlight’s […]
Talking the talk The head of EV strategy at ePropelled tells Rory Jackson how he came into the role and shares details of the company’s dynamic torque switching technology Predicting growth or decline across different areas of the e-mobility world is challenging at the best of times. These days it is even more complex, with […]
Ground vibration testing of NASA’s X-57 Maxwell electric aircraft
Electric propulsion is spawning aircraft with diverse and novel configurations. The multiple motors, rotors, propellers and fans associated with distributed electric propulsion are shaping many complex and unusual forms in the quest to enhance lift and thrust, and to reduce drag through close aerodynamic coupling with airframes. One of the most important processes in their development is ensuring that they don’t suffer from damaging vibration. To that end, NASA has used equipment from Hottinger Bruel & Kjær (HBK) to collect and process accelerometer data in ground vibration testing (GVT) for its X-57 Maxwell aircraft.
ABB plans fast-charger network for electric aircraft
As with cars and trucks, electric aircraft need access to an extensive network of reliable fast chargers, and in October it was announced that ABB is to develop a megawatt fast-charging infrastructure for Lilium’s short-haul electric jet
DSD software optimises e-aircraft powertrain designs
In early August, electrified propulsion engineering consultancy Drive System Design (DSD) revealed that it is working on optimising the propulsion systems for electric aircraft as part of the Driving the Electric Revolution (DER) challenge at UK Research and Innovation. The initial study is intended to evaluate powertrain technology that could be used on a range […]
The EV battery industry offers a variety of ways to minimise the hazards they can pose, as Peter Donaldson explains. Proximity to large amounts of energy has always presented hazards, but people have mostly learned to live with them and enjoy its benefits. However, being close to a high-energy electrochemical system such as a 100 kWh battery is still...
Hyundai and ANRA Technologies launch partnership to develop advanced air traffic operating environment
The Urban Air Mobility Division of Hyundai Motor Group has announced a new partnership with ANRA Technologies, a leading provider of end-to-end UAV and traffic management solutions, to begin developing an operating environment for the advanced air mobility (AAM) industry. This is the first in a series of air traffic management partnerships Hyundai plans to […]
Eviation unveils its production all-electric Alice aircraft as it prepares for inaugural flight
Eviation Aircraft, a global manufacturer of all-electric aircraft, has unveiled the design for its Alice all-electric aircraft, which is on track for first flight later this year. The production configuration defines Alice’s path to certification, and entry into service is expected in 2024. The Alice can carry nine passengers and two crew members. It is […]
Superconducting aircraft motors
Power density and power-toweight ratio have always been very near the top of the list of essential attributes for aircraft propulsion systems, particularly in those elements that work at the sharp end of converting stored chemical energy into thrust (writes Peter Donaldson). Rockets aside, the gas turbine engine has yet to be beaten in this respect. In the electrified...
