Aim of the Course:

Purpose of the course is to gain the general knowledge in aerodynamics of bodies of revolution, low and high aspect ratio wings and body-wing configurations. The lectures will cover mostly the linear theory. Numerical examples are run by professional dedicated programs using “practical data” to illustrate the capability of the theory.

Who should attend?

The course is intended for students, engineers - researchers in the research institutions and engineers in the productions factories. It is basic course in aerodynamics, but it is assumed that attendants have good knowledge in gas dynamics and mathematics. Deeper knowledge can be obtained from the courses Guided Weapon Aerodynamics and Aerodynamic Design of Tactical Weapons.


Duration is two weeks (twelve working days); 50 lectures (one lecture duration 45min), but other arrangement is possible.
