Objectives of Programme's Learning Outcomes

• Mobilise a structured set of scientific knowledge and skills and specialised techniques in order to carry out mechanical engineering missions, using their expertise and adaptability.
• Master and appropriately mobilise knowledge, models, methods and techniques specific to mechanical engineering.
• Assess the validity of models and results in view of the state of science and characteristics of the problem.
• Communicate and exchange information in a structured way - orally, graphically and in writing, in French and in one or more other languages - scientifically, culturally, technically and interpersonally, by adapting to the intended purpose and the relevant public.
• Argue to and persuade clients, colleagues, teachers and boards, both orally and in writing.
• Select and use written communication methods and materials, graphically or orally, adapted to the intended purpose and the relevant public.

Learning Outcomes of UE

AA - Aerodynamics : After completion of this course, the student will able to :
- identify the fundation of subsonic aerodynamics, supersonic aerodynamics and physics of turbulent.
- Establish, by using complex functions and the application of rigorous developments, the basic rules of incompressible subsonic aerodynamics of lifting airfoils for low speed subsonic flows where compressibility effects are negligible ;
- Understand and determine, when examining gas and vapor flows, the fundamental differences due to compressibility effects between subsonic and supersonic regimes and the various phenomena of saturation and the links between speed, pressure, temperature and density of compressible flows.
 
AA - Trubulence : After completion of this course, the student will have developed abilities to reproduce physical and mathematical reasoning on basic turbulent flows important in engineering. Student will also be able to analyze and characterize turbulent flows using numerical simulation or experimental results.

Type of Assessment for UE in Q1

• Oral examination

Q1 UE Assessment Comments

The UE (Educational Unit) comprises two Apprenticeship Activity (AA) : -  The  « Aerodynamics » AA - The « Turbulence » AA 

The EU's overall score is distributed as follows: -  75% for the « Aerodynamics » AA -  25% for the « Turbulence  » AA

Terms of evaluation AA "Aerodynamics" : Summative evaluation consisiting of an oral examination is carried out without the help of class notes. However, a copy of the memorandum available on the Moodle site is distributed to each student for the entire examination duration. This examination takes place on a half-day during the exams session. To assess the degree of assimilation and of knowledge of the subject (not a pure memory reproduction of relationships and content learned by heart), the examination consists of two questions drawn lots: - A general question of theory (50% of the final mark) on the subsonic aerodynamics part of the course; - A question of the form of an exercise (50% of the final mark) on the compressible aerodynamics part of the course. These questions are successively drawn lots, the answer is prepared on the blackboard and presented orally by the student. The theoretical question is a question of synthesis that covers one of the fundamental chapters of subsonic aerodynamics. The main demand is the ability to summarize and describe the main principles related to the question asked, where should dominate by the use of aerodynamic laws, though process, logic, physical interpretation, common sense and justification of the relationships and physical behaviours presented. The exercise makes a direct appeal to the notions of the compressible aerodynamics part of the course and is presented in a form similar to those presented in the course and resolved during the exercise and practical work labs. Each year, the list of chapters and the content to be learned for the oral examination is provided to students on the intranet WEB site. Unless explicitly stated in this list, the content for the examination is all the elements seen during the course and included in the copy of the slides made available as class notes for the students. The time spent by the student for the preparation and the presentation is about two hours thirty (including approximately 90 minutes of preparation).

Terms of evaluation AA "Turbulence" : The evaluation will focus on the practical work (delivery/ presentation of a personal work).

Type of Assessment for UE in Q3
