20801818 - STRUCTURAL DESIGN OF AIRCRAFT

AIM OF THE COURSE IS TO PROVIDE THE FUNDAMENTAL METHODOLOGIES ADOPTED FOR THE CONCEPTUAL DESIGN OF COMMERCIAL AIRCRAFT STARTING FROM THE MISSION REQUIREMENTS AND TAKING INTO ACCOUNT ALL THE MAJOR TECHNICAL, REGULATION AND ENVIRONMENTAL CONSTRAINTS. THE DESIGN IS CONCEIVED IN AN INTEGRATED MULTIDISCIPLINARY FASHION, WITH A CAREFUL ANALYSIS OF THE MOST ADVANCED OPTIMIZATION TECHNIQUES. DURING THE COURSE, THE STUDENTS ARE INVOLVED IN THE COMPLETE DESIGN OF A REALISTIC CONFIGURATION.

Type of delivery of the course

Traditional

Attendance

Although not mandatory, attendance is strongly recommended in consideration of the strong link existing between the theoretical part of the subject matter and the applications.

Type of evaluation

The students propose a design exercise at the beginning of the course. The proposal is approved by the teacher. The final report is evaluated with marks in thirtieths. The exam is completed by a viva voce. The final mark is the weighted sum of the two marks, v=0.45 vp + 0.55 vv.
