Hanwha is speeding up development of its urban air mobility (UAM) business, aiming to launch it by 2025.
Hanwha Systems, in cooperation with U.S. aircraft manufacturer Overair, has been jointly developing the Butterfly, which has a maximum speed of 320 kilometers per hour, capable of traveling from Yongin to Gwanghwamun Square in just 15 minutes or from Gwanghwamun to Incheon in 20 minutes.
The Butterfly is equipped with Hanwha's radar, sensors and aviation electronics technology and four electric Overair tilt-rotors capable of vertical take-off and landing (eVTOL).
The Butterfly is 100 percent electric and does not emit pollutants. It's also relatively quiet, emitting less than 65dB of noise, compared to conventional helicopters which produce over 150dB of noise. The noise level of the UAM is similar to that of a luxury sedan that makes 70dB of noise.
