Learning outcomes of the course unit
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.
Prerequisites
The basic knowledge of mechanics, structure and strength.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
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.
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.
Specification of controlled education, way of implementation and compensation for absences
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.
