STABILITY AND CONTROL DERIVATIVE CHARACTERISTICS OF THE X-15 AIRPLANE

Abstract

Flight measurements of the stability and control derivative characteristics have been made up to Mach numbers approaching the design limit (6.0) of the X-15 airplane and to angles of attack as high as 17 degrees. These data are, with minor exceptions, in generally good agreement with the predictions from wind-tunnel tests and theory. No adverse longitudinal characteristics have been uncovered; however, an area of reduced lateral-directional stability and poor lateral-directional control has been observed at moderate angles of attack due to a positive trend in the dihedral derivative for Mach numbers above approximately 2.2.
