Learning outcomes of the course unit

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.

Prerequisites

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

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline.

Assesment methods and criteria linked to learning outcomes

A course unit credit is awarded on the basis of checked presence at lectures. Presence at 10 lectures is required at least.

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.

Specification of controlled education, way of implementation and compensation for absences

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.
