Language of instruction

Czech

Number of ECTS credits

4

Entry knowledge

The basic knowledge of mechanics, structure and strength.

Rules for evaluation and completion of the course

Conditions for obtaining the course-unit credit: participation in the course (80% at the minimum). The essential exam is written (theoretical part and practical exercises), the oral verification follows.

Lectures and seminars are compulsory, and the attendance (80% at the minimum) is recorded. The absence (in justifiable cases) may be compensated after personal consultation with the lecturer and elaboration of individually assigned topics and exercises. Individual assignments must be finished and handed in credit week course-unit credits are awarded at the latest.

Aims

The goal is to make students familiar with the basics of theoretical and practical aircraft aerodynamics. Students will acquire basic knowledge of airworthiness requirements and strength calculations of main aircraft parts. They will be able to make a proper choice as for the conception, structure and material for the aircraft design.
Students will learn how to determine the basic aerodynamic parameters, flight operation and flight characteristics of a typical aircraft. They will consider the structural design from the point of view of the strength and airworthiness requirements.
