Synopsis:

The course is focused on applications of numerical calculations of flow problems, strength and mechanisms in aerospace engineering. Part of the course is to familiarize with modern software packages for the numerical solution of flow and strength.

Requirements:

No requirements.

Syllabus of lectures:

1st Unit (week 1- 5): Numerical solution of fluid flow

Mathematical models of flow, the Euler and Navier-Stokes equation and their properties, numerical solution of the task for subsonic and supersonic potential flow, basic types of numerical solvers. Modeling of turbulence. Geometry modeling, creation of computational grid. Stability of the solution, convergence. Processing of the results, optimization methods.

2nd Unit (week 6-9): Finite element method in elasticity and strength

Beam elements, 1D, 3D geometry, kinematics. Generalized forces and displacements. The shell, shell elements, classification of shell elements. FEM calculations of laminates. The calculation of the modal properties. The use of FEA in the aeroelasticity.

3rd Unit (week 10-13): Numerical solution of mechanisms
