Rolls-Royce Spirit of Innovation

Peter Donaldson examines the design and technology that went into making this electric aircraft a record-breaker. Electric aviation is roughly where piston-powered flight was in the 1920s and ’30s, in that record-breaking really matters to the credibility of the idea almost as much as to the impetus it gives to the development of electric aircraft technology.


magniX magni350, 650 and magniDrive 100

Rory Jackson looks at how these electric powertrains and their inverter have been designed for crewed aircraft integrators In every part of aerospace engineering, a race is on to break new ground and claim headline-grabbing milestones in sustainable aviation. While it might seem to some that commercial airliners are moving at a sluggish pace...


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 […]

Smart Test solutions partners up for high-power fuel cell testing project

As part of the FullStack TS fuel cell test bench project, a new generation of test benches is being developed to cover full stacks of cells of up to 200 kW. In the project, Smart Testsolutions will be responsible for monitoring the cell voltages. The project’s funding comes from the Baden-Wurttemberg Lebens-grundlage Umwelt und ihre […]


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 […]
