Stability Analysis of an F-4C Aircraft in Steady Level Turning Flight.

Abstract

A stability analysis of an F-4C aircraft (SAS off) in a coordinated, constant velocity, steady level turn is preformed. The linearized nondimensional equations of motion were used to solve for equilibrium positions about the steady turn and for the resulting aircraft motions. Five flight regions were investigated to determine the effects of altitude and speed variations for load factors ranging from 1.0 to 3.0 in 0.5 increments. Root locus plots and Argand diagrams are employed to isolate and identify three complex motions. Results indicate adverse dutch rolling motion present at moderate load factors for several flight regions.
