Analytical Study of Modifications to the Autopilot of a Fighter Airplane in Order to Reduce the Response to Side Gusts

Abstract

The response to side and rolling gusts of an airplane in combination with several types of autopilots was examined in a previous investigation (NACA TN 5603). The type of autopilot considered in the present investigation, in which heading commands are applied to the aileron channel, was found in the previous investigation to have an undesirably large roll and yaw response to side gusts; however, this type of autopilot was found to have certain salient features providing good turning response to lateral-steering commands. The present investigation is concerned with a study of the means for reducing the response to side gusts. The results indicate that, through fairly minor modifications to the rudder channel, the response to side gusts can be noticeably reduced. These modifications have no significant effect on the command response.
