Objectives

Develop an understanding of the theory of vertical flight, design and analysis of helicopters, autogyros and other rotary wing aircraft and wind turbines, and gain an appreciation of the extra difficulties involved when the vehicle flow is cyclic in nature.

Learning outcomes
After successfully completing this course, student will be able to:
1. identify the different Rotorcraft configurations and layouts
2. estimate the performance of rotorcraft in:
a. Hover
b. Forward Flight
c. Vertcial descent
3. determine the equations of motion of the rotor blades
4. determine the loads on the rotor hub
5. estimate the performance of a wind turbine.
6. determining the stability characteristics of a helicopter.

Upon successful completion of this module the following UK-SPEC learning outcome descriptors are satisfied:

A comprehensive understanding of the relevant scientific principles of the specialisation (SM1m, SM7M)
Knowledge and understanding of mathematical and statistical methods necessary to underpin their education in their engineering discipline and to enable them to apply a range of mathematical and statistical methods, tools and notations proficiently and critically in the analysis and solution of engineering problems (SM2m)
A comprehensive knowledge and understanding of mathematical and computational models relevant to the engineering discipline, and an appreciation of their limitations (SM5m)
A critical awareness of current problems and/or new insights most of which is at, or informed by, the forefront of the specialisation (SM8M)
Understanding of engineering principles and the ability to apply them to undertake critical analysis of key engineering processes (EA1m)
Ability to identify, classify and describe the performance of systems and components through the use of analytical methods and modelling techniques (EA2)
Ability both to apply appropriate engineering analysis methods for solving complex problems in engineering and to assess their limitations (EA3m, EA6M)
Ability to use fundamental knowledge to investigate new and emerging technologies (EA5m)
Ability to extract and evaluate pertinent data and to apply engineering analysis techniques in the solution of unfamiliar problems (EA6m)
Ability to collect and analyse research data and to use appropriate engineering analysis tools in tackling unfamiliar problems, such as those with uncertain or incomplete data or specifications, by the appropriate innovation, use or adaptation of engineering analytical methods (EA7M)
Awareness that engineers need to take account of the commercial and social contexts in which they operate (EL9M)
Awareness that engineering activities should promote sustainable development and ability to apply quantitative techniques where appropriate (EL11M)
