The article presents an aerodynamic analysis of the aircraft model. The process of constructing the physical model began with the development of geometry. Preliminary design was made using SolidWorks program, giving the desired shape with as many details as the method allowed. It had to be made precisely, because later it was to be printed on a 3D printer. In this phase of the project a special hole was also prepared on the model side for mounting in the wind tunnel. Important conditions were measured and written down. The applied wind tunnel - Gunt HM 170 - enabled the measurement of the lifting forces and resistance at four different air speeds (15, 20, 25 and 28 m/s) and different angles of attack - 0˚, 2˚, 4˚, 6˚ ... 16˚ and then 0˚, -2˚, -4˚, -6˚ ... -12˚. On the basis of the results obtained, the load bearing force and resistance coefficients were calculated. In order to make a comparison, a simulation was prepared in the SolidWorks Flow Simulation, using the same conditions as in the wind tunnel test. This allowed for a relative comparison of the results from tests on physical models. The obtained results of uplift and resistance forces were tabulated.
