Lectures

Goal

This course is intended to advance the technical understanding and practical knowledge of students regarding aircraft structural design. From a structural standpoint, the course is defined to help students to achieve knowledge about structural integrity according to international regulations (specifications, criteria, etc.), for designing commercial or military transports, as well as general aviation aircraft. It covers the basics of structural maintenance and repair, too. Basics of the strength of materials and structural (i.e. stress) analysis are also studied.

Outcome

Students will gather knowledge that can be used for designing and airframe structure sizing, as well as for the right choice of optimum aircraft configuration with respect to defined requirements. Also, after completing the course students will be able to carry out some structural calculations in Matlab and Excel and will have a basic understanding of the use of modern numerical methods (like finite element analysis) in aircraft design.

Theoretical teaching

1. DESIGN FOR MANUFACTURING 2. AIRCRAFT LOADS AS DEFINED BY REGULATIONS 3. MATERIALS USED IN AIRCRAFT DESIGN 4. WEIGHT CONTROL AND BALANCE OF AIRCRAFT 5. FASTENERS AND STRUCTURAL JOINTS 6. WING BOX STRUCTURE 7. EMPENNAGE STRUCTURE 8. FUSELAGE STRUCTURE 9. LANDING GEAR 10. ENGINE MOUNTS 11. ADVANCED COMPOSITE STRUCTURES 12. MAINTENANCE AND REPAIR

Practical teaching

Practical work with the lecturer serves to illustrate concepts through examples and to help students to complete their projects. After project completion students present their work to professors and other students of the department. Final grades depend on the quality of the finished projects, students’ activity during the school year, and the quality of presentations. During practical work, students use object-oriented programming for statistical analysis of known aircraft, learn how to use mechanical computer-aided design software, learn how to use and develop instruments for experimental testing, learn to use programs for finite element analysis, and create a presentation of their project work.
