The present study of the automatic interception problem is primarily concerned with investigation of the proper means of coordinating the lift-acceleration commands and the roll-attitude commands to the autopilot in order to minimize transient tracking errors encountered during bomber evasion. The study was made by utilizing a Reeves Electronic Analogue Computer to simulate simplified versions of interceptor-bomber encounters. The bomber maneuvers used during the study were designed to require various amounts of rolling on the part of the interceptor in order for it to continue tracking. Several methods of acceleration-bank coordination were studied. With some, the acceleration command was applied immediately; whereas with others, the command was delayed until the interceptor had rolled.
