Aircraft (FSI-FLE)

Academic year 2019/2020
Supervisor: prof. Ing. Antonín Píštěk, CSc.  
Supervising institute: LÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
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.
Learning outcomes and competences:
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.
Course contents:
Introduction, problem of flying and its solving. Theoretical basis of Aerodynamics and Flight Mechanics. International Standard Atmosphere, wing profiles. Aerodynamic parameters of wings and aeroplanes, flight operation and flight characteristics. The main parts of aeroplanes. Airworthiness requirements. The effects of load on an aeroplane. The basics of stress analysis of typical aeroplane parts. Materials for aeroplane structures.
Teaching methods and criteria:
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.
Controlled participation in lessons:
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.
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Exercise  13 × 1 hrs. compulsory
