Abstract

The linearized analytic model of general longitudinal movement of the sailplane is discussed. Linearized deviation equations of motion, derived in a stability co-ordinate system, are applied to the parametric analysis of the sailplane longitudinal dynamic stability for arbitrary symetric flight conditions. The analytic model is generated in the form of an interactive programming product PODYST. This is used to show the effect of some mass and geometric parameters on the short-period and phugoid motions following the disturbance from a selected reference flight condition.
