DRONE Russian patent published in 2013 - IPC B64D41/00 H02K47/14 

FIELD: transport.

SUBSTANCE: invention relates to systems exploiting drones for observation of earth surface and transmission of signals indicating location of ground structures. Invention aims at increasing output voltage required for drone onboard radar transmitter module power supply by isolating the drone onboard hardware power supply from drone onboard radar transmitter module power supply to decrease electric interferences in common power supply system. Note here that this design allows decreasing onboard radar operating range. Proposed device comprises generator with permanent magnets, controlled sync rectifier, electric power accumulator, voltage stabiliser and system control electronic unit. Permanent magnet coils number N in extra miniature sync generator is set by the ratio N≥0.005 lrB, where l is rotor length, Ir is inner radius (m), B is rotor magnetic induction.

EFFECT: simplified transmitter, higher system reliability and radar power potential.
