Abstract
The paper presents the results of numerical tests of the aerodynamics of the Gyro-One unmanned autogyro model. The geometry of the research object was developed using reverse engineering and CAD software. The created solid model of the aircraft was entered into the Ansys Meshing to generate a mesh. The boundary conditions and turbulence model were defined with Ansys Fluent software. The calculated parameters include the aerodynamic forces and the pitching moment generated on individual elements calculated with the CFD method for the selected values of the angle of attack, the velocity and pressure distributions in the plane of symmetry, and the pressure distribution on the aircraft surface for the defined measurement points. The obtained results made it possible to analyse the flow around the research object and become an introduction to further research into a hybrid multi-rotor aircraft based on the autogyro design.
