 Synopsis:

The course provides overview of key findings from aircraft aerodynamics and flight mechanics. In the first part, students are familiar with models and equations for the flow of an incompressible fluid. In the second part there are derived equations describing force and rotating effects of flow on the surface of the airfoils and wings. The important relations for effects of compressibility are derived in the next part. These findings are applied on flow around the airfoils and wings at high subsonic and supersonic speeds in last part. In the subject there are discussed basic modes of flight mechanics and basic design methods of air propellers.
