Better eVTOL landings

Battery-powered manned eVTOL aircraft intended to operate to and from urban vertiports have a sharply limited energy budget, so designing energy-efficient flight profiles for them is obviously important – and if those profiles can also improve passenger comfort and safety at the same time, so much the better

Ampaire flies first hybrid-electric regional aircraft

Ampaire’s Eco Caravan, a nine-seat regional aircraft, has made its first flight on an integrated hybrid-electric propulsion system. Ampaire expects it to be the first electrified regional aircraft to enter commercial service and the first in a series of larger Ampaire hybrid-electric aircraft. Fully electric aircraft are range-limited because of the weight and energy capacity […]

Hyundai’s Ioniq 6 design takes inspiration from cars, aircraft and nature

Hyundai Motor Company says its Ioniq 6 EV has a drag coefficient of 0.21 and an all-electric range of 614 km (WLTP-rated) on a single charge, thanks to lessons learned from some of the most streamlined shapes in automotive and aircraft history, as well as in nature. From the automotive realm, it cites the 1947 […]

Cool approach to efficient air liners

GKN Aerospace has been working on cryogenic technology to boost the efficiency of hydrogen fuel cells and electric motors for aircraft (writes Nick Flaherty). The ‘hyperconducting’ systems proposed by the company use the liquid hydrogen stored in the aircraft as fuel as a heat sink, cooling the electrical conductors to temperatures below -200 ºC to […]

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 […]
