Numerical calculation of stability derivatives of an aircraft

Tomasz Goetzendorf-Grabowski
Work presents application of methods based on the Prandtl-Glauert potential model of fluid to stability derivatives calculation of an aircraft in subsonic (Vortex Lattice Method) and supersonic (Characteristic Box Method) flow. Modeling of velocity field, next used in calculating the set of stability derivatives was shown. Results of calculation were compared with experimental data.
