Requisites:
Description: Aims:
To provide knowledge and understanding of helicopter aerodynamics, systems, design and performance, and apply this to helicopter flight scenarios.

Learning Outcomes:
After successfully completing this unit the student will be able to:
* Describe the aerodynamic theory applicable to helicopter rotors; in particular momentum and blade element models as applied to helicopters in vertical and forward flight. Critically assess the limitations of these models.
* Describe the more advanced attributes of helicopter aerodynamics, e.g., tail rotor design, dynamic stall, high Mach flows etc.
* Critically review dynamic rotor systems.
* Discuss helicopter systems: power, stability, trim etc, and the justification for design choices.
* Estimate helicopter performance (efficiency, range etc.) and critically assess the limits of this estimate.

Skills:
Problem solving; IT; numeracy; working independently; written communication.

Content:
Background and History, Review of 2D Momentum Theory for axial and forward flight, Blade Element Theory, Tip Losses, Blade Structural Design, Blade Element Theory in Forward Flight, Optimal Tip Design, Tail Rotor Design, Dynamic Rotor Systems, Flight Control Systems, Rotor Induced Vibration, Aeroelastic Effects, Helicopter Performance and Range, Future Concepts and Â鶹´«Ã½, Inverse-Problem: the Wind Turbine. Critical review of research publications related to helicopters.
