Yakovlev patents hybrid UAV with retractable lift rotors

Bottom line

Russian designer Yakovlev has patented a hybrid UAV with retractable lift rotors to reduce drag and extend range.

Why it matters

Improved range and speed for hybrid UAVs could enhance Russian long-range strike or reconnaissance capabilities.

Russian UAV channel Bespilot reports that Yakovlev has patented a hybrid UAV design featuring retractable lift rotors. The front rotors hide in fuselage niches and rear ones fold into the airflow during cruise, reportedly reducing drag by 20-30%. This design aims to extend range and speed compared to conventional multirotor or fixed-wing configurations.
