VoltAero Secures Grant For Hybrid-Electric Aircraft Development


VoltAero announced on Thursday that it has received a €5.6 million ($6 million) grant from the French government for the development of its Cassio 330 hybrid-electric aircraft. Capable of seating five people, the Cassio 330 will be powered by VoltAero’s proprietary 330-kilowatt hybrid-electric propulsion system. According to the company, the system uses electric motors for power during taxi, takeoff, flight for distances less than 150 km (81 NM) and landing while an internal combustion engine is used as a range extender and backup power system.

“This grant is another important vote of confidence in VoltAero and our vision to develop the unique family of Cassio electric-hybrid general aviation airplanes for safe, quiet, efficient and eco-friendly flight,” said VoltAero CEO and chief technical officer Jean Botti. “It contributes to the Cassio 330’s development, certification and production.”

As previously reported by AVweb, VoltAero began flight testing with its Cassio 1 test bed aircraft in March 2020. The company is also developing the six-seat Cassio 480 and 12-seat Cassio 600. VoltAero says the Cassio family is designed for use by regional commercial operators, charter companies and private owners as well as for cargo, postal delivery and medical evacuation operations.

  1. Excellent testbed to learn about using a combustion engine to move the weight of batteries and an electric motor from place to place. It will also be helpful to study the increased failure rates due to having two power systems to fail at any given time.

    I wonder if a person would need a multi rating as its technically a twin engine, if not a twin propellor. Several such aircraft were designed over the years around WWII. In any event, would be limited to centerline thrust.

    On the plus side, beautiful piece of vaporware. Looks like a copy of the Velocity XL, which by the way, already exists.

    • A three-surface aircraft like this is quite a different design to a 2-surface design like the Velocity.

  2. How about a mini avanti? Also certification of such a beast will be costly and time consuming.

  3. They could save some weight by eliminating the twin tail booms, sweeping the wing, and moving the vertical fins out to the wingtips.. 😎
