A comparative study on practical evasive maneuvers against proportional navigation missiles

In this paper, evasive maneuvers of a fighter against a missile employing proportional navigation are investigated. This work is a part of an ongoing project, Visual End-Game Simulation (VEGAS), on implementation, simulation, visualization, and evaluation of effectiveness of proportional navigation against an aircraft performing different evasive maneuvers in an air combat. Two maneuver combinations are examined; Immelmann followed by a barrel roll and split-s followed by a barrel roll. The terminal phase of the encounter is taken into consideration. An extended point-mass aircraft model including orientation kinematics is used to obtain realistic results. Sample encounter scenarios are conducted and flight time analyses are made.
