Experimental design of a UCAV-based high-energy laser weapon

Abstract

The deployment of a High Energy Laser (HEL) weapon in an airborne platform is a challenging task due to size, weight, and power (SWaP) constraints. Recent technology innovations, however, promise that such HEL development may be a reality in the near future. This study models an Unmanned Combat Aerial Vehicle (UCAV) armed with a HEL weapon and simulates the laser beam's atmospheric propagation. The Design of Experiments (DOE) methodology is then applied to determine the significance of the UCAV-HEL design parameters and their effect on the lethality of the weapon. The weight and energy requirements of two design alternatives are estimated, and the HEL output power is tabulated in relation to the UCAV endurance. Additional simulation shows the effects that platform jitter and beam quality have on the weapon lethality.
