Aircraft Structure (FSI-OSZ-A)

Academic year 2020/2021
Supervisor: doc. Ing. Ivo Jebáček, Ph.D.  
Supervising institute: LÚ all courses guaranted by this institute
Teaching language: English
Aims of the course unit:
The aim of the course is to acquaint students with basic structural units and their requirements in terms of their function and strength.
Learning outcomes and competences:
The course Aircraft Structure and Strength enables students to gain knowledge about aircraft design, load calculation and strength analysis. The student will learn to work with prescription requirements and on the basis of them design part.
Prerequisites:
Basic knowledge of general elasticity and strength. Basic knowledge of physics, kinematics and dynamics.
Course contents:
Structure and strength of aircraft acquaints students with the basic conceptual arrangements of aircraft in relation to other fields, especially aerodynamics, flight mechanics and aircraft materials. Furthermore, the course focuses on the description of individual airframe components with emphasis on the basic principles of load determination, design and strength analysis. An integral part of this knowledge is the introduction to the theory of thin-walled structures and their calculation.
Teaching methods and criteria:
The course is taught in the form of lectures that have the character of explanation of basic principles and theory of the given discipline. The exercise is focused on practical mastery of the subject matter covered in the lectures. Teaching is complemented by laboratory exercises.
Assesment methods and criteria linked to learning outcomes:
The course-unit credit requirements 90% attendance at seminars. It is also necessary to submit completed and elaborated computational exercises. The exam is written.
Controlled participation in lessons:
90% participation in exercises, elaborating a protocol, presentation of all tasks from exercises.
Type of course unit:
    Lecture  13 × 5 hrs. optionally                  
    Laboratory exercise  1 × 2 hrs. compulsory                  
    Exercise  12 × 2 hrs. compulsory
