Course outcomes:

At the end of the course the student will be able to:

1. Apply fundamentals of structural analysis of airframe parts

2. Demonstrate knowledge of structural design process, and various failure theories

3. Model airframe life assessment and design against fatigue

 

Question paper pattern:

The SEE question paper will be set for 100 marks and the marks scored will be proportionately reduced to 60.

  • The question paper will have ten full questions carrying equal marks.
  • Each full question is for 20 marks.
  • There will be two full questions (with a maximum of four sub questions) from each module.
  • Each full question will have sub question covering all the topics under a module.
  • The students will have to answer five full questions, selecting one full question from each module.
