Safran electric motors to power TCab Tech’s eVTOL aircraft

Chinese-based TCab Tech has announced that it will be using Safran Electrical & Power to supply six of its ENGINeUS electric motors to power the E20 eVTOL aircraft.

Safran is aiming to certify its electric motors in 2023, and said its ENGINeUS family of motors offer power outputs ranging from single digits to 500 kW. The company said the electric motors that will be used in the E20 eVTOL aircraft will deliver more than 100 kW of power and features a fully integrated motor controller within the machine. The thermal management is provided by an optimized air-cooling system.

Yinji Huang, chief engineer of TCab Tech, said electric motors are a critical design consideration for any eVTOL aircraft, driving the aircraft configuration and weight, rotor size and noise, battery pack voltage and power, propulsion system architecture, and thermal management.

“Collaboration with Safran increases the maturity level of our aircraft design, especially the electric propulsion system design,” Huang said.

TCab is developing a five-seat passenger-carrying eVTOL aircraft with six propellers — four tilt-propellers used for forward flight and transition, and two double-stacked fixed propellers for lift. It has a high gull-wing with a conventional tailplane design, and the aircraft is targeting a maximum range of 200 kilometers (125 miles) and cruising speed of 260 km/h (162 mph).

The company is aiming to receive type certification from the Civil Aviation Administration of China (CAAC) by 2025, making progress with its flight test program after achieving transition flights with a half-scale demonstrator earlier this year.  

Last year, the company secured US$10 million during two rounds of fundraising, and also became a member of the Vertical Flight Society.
