UNMANNED AIRCRAFT COMPLEX Russian patent published in 2018 - IPC B64C29/02 B64C39/02 

FIELD: aviation.

SUBSTANCE: unmanned aircraft complex (UAC) comprises an unmanned ring wing synchro porter and a transport-launching container. The ring wing synchropter contains four nacelles outside the round wing, engines which drive by means of transmission propellers, quadricycle landing gear with non-retractable shock-absorbing struts and configured in the "tailless" aerodynamic design with said ring body-wing equipped with arrow-shaped cantilevers of cross-shaped outer wing at the ends of the nacelles, and the concept of tier arrangement of crossed propellers. The propellers are mounted on elongated V-shaped output shafts forming V-shaped reduction gears inclined by 15° from the vertical, respectively, both from and along the plane of symmetry. The main reduction gear is mounted inside the body-wing on profiled stiffening ribs and arrow-type sections of the inner wing.

EFFECT: increased weight yield, improved transverse and longitudinal controllability, increased altitude and range of flight.
