Abstract

Nowadays there is an increased interest in countering military drones/UAVs in flight. One countermeasure is based on using high power laser (HPL) to destroy them. We report part of the numerical simulations of optimizing the duty cycle of a drone/UAV destruction laser. The main task was to determine the temperature distribution over the area of the fuselage targeted by the laser in order to discover the laser parameters needed to melt the fuselage and make a hole through the fuselage. The simulations were performed for zero to infinite thicknesses and in motion and represented the input data..
