MODULAR UNMANNED AERIAL VEHICLE WITH TRACTION PROPELLERS PROTECTION SYSTEM Russian patent published in 2021 - IPC B64C39/02 B64C27/10 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aviation, in particular to the designs of unmanned aerial vehicles (UAVs). The UAV has a rigid supporting frame, two oppositely rotating engines with automatic skewing of fixed-size propellers are located and rigidly fixed on one central axis. Eight hollow sealed modules, rigidly fastened to the supporting frame and to each other through seals, form a rigid aerodynamic profile with a protective grid on top and bottom with engines and propellers inside. The power elements of the propellers, the control system with navigation, the device for collecting and processing information are located inside sealed hollow modules that allow landing on a solid and water surface with the possibility of subsequent takeoff. The supporting rigid frame and UAV modules are made of high-strength plastic, which provides rigidity, reliability and low weight of the structure.

EFFECT: creation of a modular design is provided, which makes it possible for the UAV to land and take off from solid and water surfaces.
