New quiet and safe electric ducted fans for small aircraft
The most common solution in the field of small aircraft and UAS are open-rotor systems, but these systems have significant problems limiting their use. A high noise level (more than 90 dB), a low level of safety (a high risk of foreign objects entering the flow part), as well as the location of open rotors at the level of human height, according to surveys, causes fear among respondents

The main competitive advantages of the proposed solution are: low noise, increased safety and efficiency. So, according to the calculations carried out, in comparison with German analogues with the same peripheral diameter, the engine under development has an efficiency 5% higher and a noise level 12% lower. Also, in comparison with the leading manufacturer of open-rotor systems, the developed solution is quieter by 37%, with comparable thrust indicators, the peripheral diameter is less than 6 times smaller, and the range of flight speeds is expanded to 150 m/s
