Prerequisite
Aircraft Design, Aircraft Science
Rationale
The aerodynamics of a rotary wing aircraft differs significantly from that of a fixed wing aircraft and it is important to study this variation to understand the working of a helicopter. The physics and underlying theories required to be studied before actually embarking upon the design of a helicopter are included within this content
Course Outcome
After learning the course the students should be able to:
1. Understand the significance of replacing existing metal structures with composite materials wherever beneficial
2. Highlight the appropriate use of composite structures in the industry
3. Comprehend the complexity of design of composite materials and structures
4. Mainly understand the mechanics of composite materials

Active Learning
Preparation of power-point slides, which include videos, animations, pictures, graphics for better understanding theory and practical work – The faculty will allocate chapters/ parts of chapters to groups of students so that the entire syllabus to be covered. The power-point slides should be put up on the web-site of the College/ Institute, along with the names of the students of the group, the name of the faculty, Department and College on the first slide. The best three works should be submitted to GTU.
1. Chronological development of helicopters
2. Chronological development of engine in helicopters
3. Axial flow states of helicopter
4. Blade element analysis in forward flight
5. Blade element analysis in hover and axial flight
6. Momentum analysis in hover and axial flight
7. Momentum analysis in forward flight
8. Conceptual design of main rotor
9. Making of a innovative hovering model
10. Performance of helicopters
11. Types of airfoils used in helicopter main rotor
12. Differences between main rotor and tail rotor
13. Autorotation and Ground Effect
14. Blade vortex interaction
15. Working and mechanism of Swashplate
