Drone With Infinite Flight Time Developed

Sci­en­tists have pre­sent­ed an unusu­al project that allows drones to stay in the sky almost indef­i­nite­ly. Recharg­ing is car­ried out direct­ly in flight, thanks to remote recharge by a laser. The devel­op­ment is use­ful for the agri­cul­tur­al indus­try, MSCh, as well as oth­er impor­tant areas of human activ­i­ty.

The idea of ​​the engi­neers is to trans­form the laser beam into a “charg­er” for the drone. A pho­tode­tec­tor was placed on the device, which con­verts the incom­ing laser light into elec­tric­i­ty. To bring the idea to life, it was nec­es­sary to cre­ate a spe­cial­ized sys­tem that tracks the move­ments of the drone. It is able to detect the device regard­less of weath­er con­di­tions or time of day.

The effi­cien­cy on the trans­mit­ting side is in the range of 50–85%. Much depends on the pow­er of the beam. But the device can accept “charg­ing” rather poor­ly, los­ing up to 50%. But this is not crit­i­cal, because tests are still being car­ried out, and the main goal, feed­ing the drone with a laser, has been suc­cess­ful­ly achieved.

If the sys­tem is worked out, gigan­tic prospects will open up. For exam­ple, it will be pos­si­ble to con­trol the move­ment of vehi­cles, use devices in res­cue oper­a­tions, etc.
