Sustainable Development Goals
Learning Goals
After concluding this course, the student should have had acquired technical skills in incompressible and compressible aerodynamics, being able to understand the different phenomena and to utilize several solution methods. He/she should be able to analyse problems that involve interior and exterior flows, in the laminar and turbulent regimes, airfoils and finite wings. The student should also dominate the terminology used in aerodynamics and be able to search and critically interpret relevant scientific information about the topics covered. He/she should be able to conduct simple experimental tests and combine the experimental data obtained with the theory learned. The student should be able to write, orally present and discuss studies performed according to universally accepted rules and with the resource of computer software.

Teaching Methods
Exposition of the syllabus in theoretical lectures, problem solving classes in theoretical-practical lectures, and laboratory experiments performed in practical-laboratory classes. Seminars by invited specialists.
Assessment
The grades are within the interval [0,20].
Continuous assessment or by final exam, in accordance with the Academic Regulations of the University of Évora.
The assessment method consists of the following components:
• [RL] Laboratory Report (30%).
• [T1] Test 1 (35%).
• [T2] Test 2 (35%).
• [E] Final Examination (70%)
The student can choose between 1 out of 2 possible assessment methods, where the Final Grade [NF] is calculated according to the following:
i) CONTINUOUS ASSESSMENT: NF = RL*0.30 +T1*0.35 +T2*0.35
if NF> 9.5 ^ RL> 9.5 ^ T1> 8.0 ^ T2> 8.0 then Student Approved
ii) FINAL ASSESSMENT: NF = RL*0.3 +Ex*0.70
if NF> 9.5 ^ RL> 9.5> 9.5 ^ E> 9.5 then Student Approved
