The Zimmerman-Weissenburger approach presents an innovative tool to predict the onset of flutter during a flight test. This approach computes flutter margins as the distance from any test point to that onset point by noting a flutter function, which relates stability of the aeroelastic dynamics, has approximately a quadratic dependency on dynamic pressure. The approach has assisted envelope expansion for many flight tests; however, it is limited to consideration of 2-mode coupling for thedoi:10.2514/1.40328 fatcat:3lt22k7nkrfg3gbphpuwbt2zvq
