AbstractStudents develop and build a product from A-Z! They work in teams and independently, learn to structure problems, to identify solutions, system analysis and simulations, as well as presentation and documentation techniques. They build the product with access to a machine shop and state of the art engineering tools (Matlab, Simulink, etc).
ObjectiveThe various objectives of the Focus Project are:
- Synthesizing and deepening the theoretical knowledge from the basic courses of the 1. - 4. semester
- Team organization, work in teams, increase of interpersonal skills
- Independence, initiative, independent learning of new topic contents
- Problem structuring, solution identification in indistinct problem definitions, searches of information
- System description and simulation
- Presentation methods, writing of a document
- Ability to make decisions, implementation skills
- Workshop and industrial contacts
- Learning and recess of special knowledge
- Control of most modern engineering tools (Matlab, Simulink, CAD, CAE, PDM)
- Convert and experience technical solutions
ContentAmong the solutions to promote the growth of renewable energy technologies and the development of Green Cities is the expanded use of small wind turbines. Technical innovations in the design of small wind turbines are required in order to reduce the cost of the wind-generated electricity, such the wind turbines are more widely used.

The goal of the UrbanFlow project, which will be undertaken by two teams, is to design and build efficient & cost-effective prototype wind turbines for two possible applications:
1. Urban settings, with wind turbines integrated into a building.
2. Developing countries, with optimised use of local materials.

The project shall involve highly interdisciplinary teams, which shall address issues including:
- Structural mechanics and fluid dynamics
- Noise control & visual impact
- Systems integration
- Analysis of cost, lifecycle & manufacturability

The project elements shall include:
- Evaluation of wind measurements or predictions for identified locations
- Mechanical & architectural design
- Aerodynamics, structures & noise
- Electrical systems & electronic controls
- Economics & manufacturability analysis

The teams, each comprised of 6-8 students, will be formed by the end of May 2013.
LiteratureOnly public learning materials are listed.

151-0204-00LAerospace Propulsion4 credits2V + 1UR. S. Abhari, N. Chokani
AbstractIn this course, an introduction of working principals of aero-engines and the related background in aero- and thermodynamics is presented. System as well as component engineering aspects of engine design are examined.
ObjectiveIntroduction of working principals of aero-engines and the related background in aero- and thermodynamics. Engineering aspects of engine design.
ContentThis course focuses on the fundamental concepts as well as the applied technologies for aerospace application, with a primary focus related to aviation. The systematic evolution of the aircraft propulsion engines, from turbojet to the modern high bypass ratio turbofan, including the operational limitations, are examined. Following the system analysis, the aerodynamic design of each component, including the inlet, fan, compressor, combustors, turbines and exhaust nozzles are presented. The mechanical and material limitations of the modern designed are also discussed. The environmental aspects of propulsion (noise and emissions) are also presented. In the last part of the course, a basic introduction to the fundamentals of space propulsion is also presented.
