Zusammenfassung:
An integral mathematical model describing the longitudinal motion of a flexible aircraft is presented.
Unsteady aerodynamic loads on the wing and horizontal tail with flap in compressible flow are
calculated using a linear, time domain model based on the indicial response method. Wing and
horizontal tail are treated as a flexible beam. Lagranges equation and the principle of virtual work are
applied to generate the structural equations of motion. Since this mathematical model is constructed in
state space form, it can be widely used in flexible aircraft simulation. A generic: elastic aircraft is
calculated as a numerical example through this paper. Three research topics for flight dynamics
analysis will be given in this work. The stability comparison of the Oexible aircraft and rigid aircraft,
the inßuence ofvarious parameter changes to a flexible aircrafts characteristics and design of stability
augmentation system for the example aircraft applying two optimal syntheses, namely, linear quadratic
regulator and genetic algorithm.
