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 […]

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 […]

Battery Safety

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...


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...

Axial flux motors

Axial flux motors have many EV design advantages over their radial flux counterparts, as Nick Flaherty explains. A new type of motor is gaining traction in the e-mobility sector – the axial flux type. For many years they have been used in stationary applications such as elevators and agricultural machinery, but over the past decade a number of developers have been working on improving...


Pipistrel Alpha Electro

Lawrence Butcher explains how this electric two-seater, airworthy certified aircraft was developed and how it acts as a pointer to the future. Electric aircraft are by no means a new invention: the first recorded electric powered flight was in 1973, by...


eVTOLs distribution deal

VerdeGo Aero, a US company with the goal of producing an eight-rotor eVTOL air taxi – and headed up by Erik Lindbergh, great-grandson of aviation pioneer Charles Lindbergh – is developing a distributed power system that could be marketed to other eVTOL aircraft developers (writes Lawrence Butcher). The company’s design, referred to as...


Diesel digger goes electric

US motor maker Dana has developed a custom electric drivetrain for compact excavators (writes Nick Flaherty). The drive for Mecalac’s e12 electric compact wheeled excavator uses Dana’s Spicer 112 axles and a Spicer 367 shift-on-fly transmission. The 146 kWh LiFePO4 batteries in the area previously occupied by...


Smoothing road to electric

In recent months, efforts by Tesla and Toyota to bring electrification to semitrailers for road freight have made the headlines (writes Lawrence Butcher). The goal of full electrification, as sought by these companies, is an admirable one, but in the near term, there is much that can be achieved through...
