Bye Aerospace tests eFlyer 2 prototype with 90 kW Siemens motor

E-plane startup Bye Aerospace has begun flight tests of its two-seat eFlyer 2 prototype, equipped with a new 90 kW Siemens SP70D production motor. The new motor weighs 57 pounds and features a 90 kW peak rating (120 hp) and a continuous power rating of 70 kW (94 hp). In addition to the new motor,… Read more »

Boeing partners with Kitty Hawk for electric air mobility efforts

Boeing and Kitty Hawk have entered a partnership to collaborate on future efforts to advance safe urban air mobility. California-based Kitty Hawk builds electric aircraft, including Cora, a two-person air taxi, and Flyer, a vehicle for personalized flight. “Working with a company like Kitty Hawk brings us closer to our goal of safely advancing the… Read more »

Siemens sells electric aircraft propulsion business to Rolls-Royce

Siemens is set to sell its eAircraft unit to Rolls-Royce – the companies expect the move to take place in late 2019. Siemens eAircraft develops electric and hybrid-electric propulsion systems for the aerospace industry.

NASA awards researchers $6 million to develop fuel cell aircraft

NASA has awarded a team from the University of Illinois, Urbana-Champaign $6 million to support research into an electric aircraft. The team will research the use of liquid hydrogen in fuel cells to power an aircraft propulsion system. They also intend to develop a design concept integrating superconducting electrical components into an aircraft that is… Read more »

Boeing completes test flight of autonomous electric passenger aircraft

Boeing has completed the first test flight of its autonomous passenger air vehicle (PAV) prototype in Manassas, Virginia. The PAV prototype completed a controlled takeoff, hover and landing during the flight, which tested the vehicle’s autonomous functions and ground control systems. Future flights will test forward, wing-borne flight as well as the transition phase between vertical… Read more »

Rolls-Royce hopes to shatter electric airplane speed record

A partnership led by Rolls-Royce is building an electric aircraft that it hopes will reach a top speed of over 300 mph and beat the previous speed record of 210 mph set in 2017 by Siemens. The project is part of a Rolls-Royce initiative called Accelerating the Electrification of Flight (ACCEL), which is partly funded… Read more »

University of Illinois puts hybrid aircraft to the test in simulation

Automobiles are trending towards electric power – but what about their counterparts in the sky? Jet fuel and aviation gasoline are very energy-inefficient, but they have one big advantage: they’re lightweight. Every gram matters in the aerospace industry. That’s why electrifying an aircraft is so difficult: although batteries would be much more efficient than jet… Read more »

Amprius’s silicon nanowire batteries power the Zephyr S HAPS solar aircraft

Battery manufacturer Amprius is supplying lithium-ion cells to Airbus’s Zephyr program. Using Amprius’s cells, which contain a 100% silicon anode, the Zephyr S solar-powered unmanned aerial vehicle (UAV) recently flew more than 25 days, setting a new record for stratospheric flight. The Zephyr S is a high-altitude pseudo-satellite (HAPS), which combines the persistence of a… Read more »

Audi says flying taxis are on the way

During the recent Amsterdam Drone Week event, Audi, Airbus and design and engineering firm Italdesign presented a flying car prototype called the Pop.Up Next. The concept combines a self-driving EV with a passenger drone, and features a passenger capsule that can be removed from its wheels and picked up by the flying drone. The prototype… Read more »
