  "textContent": "The disclosure relates to an electric aircraft propulsion assembly (300) for an electric vertical takeoff and landing, eVTOL, aircraft (100), the assembly (300) comprising: an electric storage unit (302); a first electric motor (303) connected to power a first propulsor (305); a first converter (307) configured as a DC:AC converter for driving the first electric motor (303) and a second electric motor (304) connected to power a second propulsor (306), a second converter (308). A controller (310) is connected to control operation of the first and second converters and is configured to operate in a first mode in which the first and second converters (307, 308) are operated as DC:AC converters to drive the first and second electric motors (303, 304) and a second mode in which the first converter (303) is operated to drive the first electric motor (303) to power the first propulsor (305) and the second converter (308) is operated to drive the second electric motor (304) to provide a braking torque on the second propulsor (306).",
