Verification of Selected Model Coefficients for a Small Unmanned Aircraft

This article presents design and analysis of mathematical model UAV with fixed wings. The mathematical model serves to understand the basic mathematical principle and physical laws, that are applied to the system, and is indispensable in UAV movement simulation and modelling of the control algorithms. The article also describes the methodology of individual modelled parts using the XFLR5, where effective numerical methods are used for mathematical modelling. The last part provides verified and reliable results obtained by simulations of a mathematical model, which will be used to simulate basic and critical situation states.
