Small fixed-wing unmanned aerial vehicles (UAVs) have proven
themselves as invaluable assets for reconnaissance and surveillance
missions. Their improvement and further development most often
focuses on improved endurance, datalink range, camera capabilities
etc. This paper presents a modular approach to “Vrabac” UAV
improvement by integrating wing payload extensions, enabling
precision aerial drop capabilities. This enables precise delivery of
lethal or non-lethal payloads from the UAV at pre-determined
coordinates or at a visually aquired target. Precision aerial drop
software module is presented, focusing on the automated payload drop
algorithm with continually calculated impact point prediction (CCIP)
and UAV guidance to the continually calculated release point (CCRP).
The chosen ballistics computation and control system implementation
evaluates UAV flight parameters, wind direction and velocity,
terrain profile etc. to achive a precise target strike. Simulated
results with a parameter sensitivity analysis, as well as field test
results are presented.
Key words: Unmanned Aerial Vehicle, Precision Drop, Control
Design, Modular Design.
