Estimation of Stability Parameters for Wide Body Aircraft Using Computational Techniques

In this paper, we present the procedure of estimating aerodynamic coefficients for a commercial aviation aircraft from geometric parameters at low-cruise-flight conditions using US DATCOM (United States Data Compendium) and XFLR software. The purpose research was to compare stability both pieces software determine efficacy solution wide-body stated flight conditions. During initial phase project, were acquired established literature. next phase, control estimated in parallel. Results obtained compared any differences validated with analytical correlations as presented plots various variations angle attack or surface deflection have also been presented. between solutions results can be associated approximations techniques used (the vortex lattice method is background theory XFLR). Additionally, results, it concluded that more reliable than longitudinal, directional, lateral stability/control coefficients. Analyses Boeing 747-200 (a airliner) complete analysis including all modes longitudinal directions already has sample previous version 737; however, much larger former, was, therefore, felt necessary study its aerodynamics characteristics. Furthermore, research, categories alike terms general coefficients, hence many dependably modeled analyzed
