Entry knowledge

Basic knowledge of mathematics, differential and integral calculus, ordinary differential equations.
Basic knowledge of physics, mechanics, statics and dynamics.

Rules for evaluation and completion of the course

A course unit credit is awarded on the basis of checked presence at lectures. Presence at 10 lectures is required at least.
A course unit credit is not awarded unless the presence at lectures is less then 10. In the case of a long term illness (or similar cases) small part of lectures (max. 2 lectures) may be compensated by consultation and home study.

Aims

Students will gain basic information on simple methods of aerodynamic design for aeroplane propellers, low pressure axial compressors, wind power propellers and information on helicopter rotors.
Students will gain the knowledge how to compute and design an aeroplane propeller, low pressure axial compressor and propeller for a wind power station from the aerodynamic point of view. Motion of rotor blades of helicopters will be described too.
