Learning outcomes of the course unit

Students acquire skills and knowledge of work at work-stations, they are made familiar with structure design systems using 3D modelling theory. They learn the basics of CATIA V5.

Prerequisites

Basic knowledge of computer geometry. Basic knowledge of any lower CAD system level (AutoCad, Inventory etc.).

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. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Graded course-unit requirements: a project must be submitted in a prescribed form and handed in by the deadline, The project assessment is done individually and in accordance with FME BUT rules.

Aims

The course objective is to make students familiar with design methods of aircraft structure using computer systems and with valid rules of the aircraft structure design.

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

Lectures and exercises are compulsory, and the attendance (80% at the minimum) is controlled and recorded. The absence (in justifiable cases) can be compensated by personal consultation with the lecturer.
