Due to its advantage of long endurance,high aspect ratio loitering munition has been increasingly used in local conflicts in recent years.Suspending and releasing loitering munition on fixed wing aircraft is an important combat method,and due to differences in speed,there may be separation safety concerns during the releasing pro-cess.This article analyzes the characteristics of the deceleration process during the release of high aspect ratio loi-tering munition on a fixed wing aircraft.Simulation analysis has been conducted on the conventional deceleration method based on the drag chute,the deceleration method based on the combination of the missile launcher/drag chute,and the variable configuration gliding deceleration method with the wing unfolding in stages so as to provide thoughts for the design on releasing methods of airborne loitering munition.
