eVTOL (electric Vertical Take-Off and Landing) refers to a new generation of electrically powered aircraft capable of vertical takeoff and landing. As a key technology in Urban Air Mobility (UAM), eVTOL combines the vertical lift capability of a helicopter with the efficient forward flight of a fixed-wing aircraft. It is widely used in emerging fields such as urban air transportation, short-distance travel, emergency response, medical delivery, and high-value logistics. With advantages such as low noise, zero emissions, high safety, and efficient operation, eVTOL is becoming a transformative solution for the future of air mobility.
