VoltAero chooses Safran electrical wiring to equip Cassio 330 certification aircraft

Safran Electrical & Power has been selected to supply the electrical wiring on VoltAero’s Cassio 330 electric-hybrid certification aircraft, confirming Safran’s role as a leading partner in VoltAero’s clean-sheet e-airplane.

With this contract, Safran Electrical & Power will design and produce electrical wiring for the propulsion system and power distribution system – in particular, the high-voltage wiring – on the Cassio 330 to be utilised in the certification programme of this first member of VoltAero’s aircraft family. The wiring will be qualified for power ratings up to 800 Volts in continuous operation and is to be designed to resist partial discharge phenomena at altitude. At the equivalent size of cabling produced today for traditional aircraft, the Cassio wiring will carry power levels twice as high. 

“The electrical wiring is a critical element of our Cassio aircraft and we’ve selected Safran Electrical & Power based on the company’s expertise – particularly at high power levels,” explained Jean Botti, VoltAero’s CEO and Chief Technology Officer. “This marks another important step toward the Cassio 330’s certification and service entry.” 

Safran Electrical & Power will provide its technical expertise to support VoltAero in obtaining the SOF (Safety of Flight) validation – a pre-requisite for carrying out the Cassio 330’s certification flight tests. 

This contract extends a partnership signed in 2020 involving the Cassio 330’s electric-hybrid propulsion system. Safran Electrical & Power is to supply the propulsion system’s ENGINeUS 100 electric motor, which delivers a maximum power of more than 150-kW at take-off. The ENGINeUS 100 integrates its own control electronics as well as an air-cooling system, ensuring an optimal size-to-power ratio.
