AIRCRAFT POWER SUPPLY METHOD AND DEVICE (VERSIONS) Russian patent published in 2015 - IPC B64F3/02 H02J3/26 H02J5/00 H02J17/00 

FIELD: electricity.

SUBSTANCE: group of inventions is related to above-ground structures for tethered aircraft. The first version of a power supply method for an aircraft with a tether line is characterised by the fact that power supply from the ground is carried out with high voltage of 0.1-10 kV by converting the voltage of the ground power supply source from 12-380 V to 0.1-10 kV and then transmitted through a transmission line with the further conversion of the voltage from 0.1-10 kV to 12-380 V. The second version is characterised by transmission of power from the ground in a resonant way at the high frequency of 1-25 kHz by the conversion of the ground surface in the voltage and frequency from 12-380 V to 0.1-10 kV, 1-25 kHz and transmission through transmission lines with the further conversion of the cable line voltage from 0.1-10 kV up to 12-380 V. Each version of the power supply device is characterised by the usage of the respective voltage converters.

EFFECT: group of inventions is oriented to the increase of the power supply range and altitude.
