Abstract

In the field of Appred Aerodynamics, the evaluation of aerodynamic derivatives is essential for analysis of stability and control of flying bodies. In the present work some of important stability and control derivatives are calculated theoretically for a rectangular wing in an incompressible flow The theoretical solution is realized on the basis of two different methods; the Multhopp's method and the Von& Lattice Method (VLM). An experimental evaluation of the calculated derivatives is also performed. The experimental study was carried out by the testing of a wing model in a general-purpose low speed wind tunnel. A good agreement was found between theoretical and experimental results.
