Longitudinal Dynamic Stability Analysis of a Lippisch Type WIG Craft

The longitudinal stability of a ۲۰-passenger Lippisch typeWing-In-Ground effect craft in cruise flight for differentcruise heights and conventional wing design parametershas been reported in this paper. The sensitivity ofconventional wing design parameters on dynamiccharacteristics of each WIG dynamic modes has beeninvestigated. The linear model is constructed in statespaceform using small perturbation theory and thevehicle’s aerodynamic derivatives are computed using asemi empirical method USAF Digital DATCOM.
