Abstract: In view of the difficulty of traditional air defense means to effectively deal with the problem of UAV swarm, the concept of anti-bee swarm of rotorcraft flight platform equipped with high-energy laser is proposed. Firstly, through the study of the combat characteristics of typical swarms, the possible application modes of UAV swarms are analyzed. Secondly, by analyzing the characteristics of the existing air defense interception system, the application method of the rotorcraft flight platform carrying high-energy laser weapons to combat the swarm is introduced. Finally, the possible application scenarios, killing modes and strike processes of rotorcraft airborne high-energy laser weapons are analyzed and studied. The characteristics of the light speed attack, point and surface killing, and all-weather strike of the high-energy laser weapon equipped on the rotor flight platform are extremely suitable for the application scenarios of the swarm attack, which can intercept the incoming swarm more efficiently and reliably ensure the safety of important facilities.
