Learning outcomes of the course unit

Students will gain basic information about aircraft structures and certified requirements they have to meet.
Students acquire the knowledge necessary for evaluation of technological influence and design from technology point of view on the aircraft structure final performance.

Prerequisites

Basic knowledge of physics, strength and elasticity of beams.
Basic knowledge of the structure, phase transformations and properties of metal structural materials. Basic technological principles and methods of materials processing – heat treatment, sheet forming, welding.

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. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

Course-unit credit requirements: participation in exercises (90% at the minimum).
Exam: written – tasks from aircraft strength.

Aims

The goal of lectures is to familiarize students with basic aircraft parts and strength and function requirements.
To inform of aircraft manufacture specific attributes and methods and procedures, which are necessary for operation specialists.

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

90% participation in exercises (80% at the minimum), elaborating a protocol, presentation of all tasks from exercises.
