Mean Flow Refraction Corrections for the Kirchhoff Method

pitch rate of 210.5 deg/s, which is the value of q in Fig. 3 corresponding to p = 0 in the unconstrained case. Computed PSS solutions for the roll rate and sideslip in this case are also shown in Figs. 1 and 2. The Ž gures show that multiple attractors persist even with the additional pitch rate constraint. The aircraft shows a jump at da ’ 212 deg at the saddle-node bifurcation point that occurs for (a, b) ’ (24, 1) deg. It follows that even when the elevator is used to maintain constant pitch rate in a rapid VVR maneuver, the rudder does not suppress sideslip for large da.
