Florida startup Undefined Technologies says it has taken a major step in developing a drone it believes could change the entire blossoming UAV service industry by using quieter, powerful ionic propulsions systems rather than rotors to drive UAVs.

Undefined Technologies says it passed a testing milestone this month with a 4.5-minute flight of its drone using ionic propulsion, emitting just 75 dB of noise in the process. That trial marked further advances in the company’s development of the approach, extending time aloft over previous outings while lowering the level of sound produced. 

If successful, the continued development of ionic propulsion is considered a potential boost for various kinds of drone service providers – particularly aerial delivery companies – by slashing attendant noise levels that consumers have continually pointed to as one of their major oppositions to UAV activities.
