Supervising institute: LÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
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.
Learning outcomes and competences:
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.
Course contents:
Lectures present aircraft design fundamentals. Airworthiness requests are defined Requirements on structure, detail of design of wing, fuselage, tail planes, landing gear and power mount. Examples and training stress analysis of different types of aircraft structures.
Next follow, basic aircraft materials. Technology of heat treatment. Forming techniques in aircraft manufacture. Riveting, welding and adhesive bonding of aircraft structures. Fundamentals of composites and sandwich structures manufacturing. Basic surface treatment procedures. Repair techniques.
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. 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.
