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 […]


The power of decay

Launched on September 5, 1977, NASA’s space probe Voyager 1 is now the most distant human-made object in existence (writes Peter Donaldson). At the time of writing, the spacecraft had made it more than 14,569,656,000 miles from the Sun, a figure that continues to grow at a rate of about 38,027 mph. The probe is […]

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.
