Aerodynamics is a very broad quantitative science, with
applications in aerospace
(airplanes, helicopters, spacecraft, missiles, dirigibles, balloons), propulsion (jet
engines, propellers, rockets), ground systems (motor vehicles, wind turbines,
suspension bridges), flows in complex systems (exaust gases, radiators, engine
inlets) to name just a few. Its closest disciplines are fluid dynamics,
aeroelasticity and aircraft design.
In spite of this practical side, aerodynamics is a theoretical discipline, that
requires the support of mathematics (vector analysis, differential equations,
integration, differentiation, complex calculus, etc) and solid programming skills
(for those who actually solve aerodynamic problems).
Aerodynamics is one of those disciplines affected by a huge gap between what can be
covered in an course and the application of the theory to analysis and design. For
this reason the going may seem rough. Many students find the theory quite difficult
to follow. You are encouraged to develop your analytical knowledge and to seek help
whenever you find yourself in difficulty.
The experimental part of this course is an opportunity to solve engineering problems
and to show the results in a concise and explanatory manner through a technical report.

 Additional Literature (http://aerodyn.org/Frames/1biblio.html)
for the enthusiasts (including critical book reviews)
NB: Notes and laboratory handouts will be distributed during the course. For security reasons no documents will be posted through the Internet.
Assessment
 2 hour closedbooks exam at end of the year, 80 %
 Laboratory work, 10 %
 Mid term assignment, 10 %
NB: Date and place of the exam is set by the undergraduate during
the year.
Course Work Policy
 All laboratory work is to be submitted within
3 weeks from the date of the experiment
 Course work submitted after deadline will not be marked.
 Extension of the deadline can be granted, but only on a casebycase basis
 The report must be submitted directly to Dr. Filippone, before or after lectures
 Reports cannot be submitted via email or fax
How Much Should you Study ?
For every hour of lecture you are expected to
 have two hours of study, or
 one hour of tutorial and one hour of study
NB: You are encouraged to solve standard problems, for example past examination papers,
that are available from the undergraduate offices.
Seeking Help
 The instructor will be available to answer students questions after each lecture or tutorial.
 The instructor is available for questions in his office on Mondays and Thursdays at
17:0018:00, or via email at any time.
Rules of Conduct in the Class Room
 Mobile telephones are to be switched off at all times.
 Students are expected to be punctual and lectures to start on time.
 Silence is expected from the students.
 Background noise will not be tolerated.
 Horseplay and willful misconduct have no place in the class room.
 No Eating, No drinking

on the Students Chart.
Rules of Conduct in the Laboratory
 Laboratories are to start on time. Students arriving late disrupt the
experiment and miss the introductory lecture; They keep experimental officers
and expensive equipment on standby. Delay at the start may compromise the completion
of the work.
 The schedule must be respected. Students CANNOT show up at a different date
or at a different time, because this poses problems in the organization. If students
fail to show up at the experiment that is assigned to them, they will get
zero credit.
Ethical Standards
Ethical standards are needed to avoid cases of plagiarism and cheating. These include
(but are not limited to): attempts to submit laboratory reports and course work
without attending experiments/lectures; submitting the work done by another person;
failure to give credit for ideas; photocopying books and publications covered by
Copyright. Assisting other persons to cheat is also considered an offense, and may be
subject to disciplinary procedures. Acts of plagiarism are reported to the
undergraduate office and to the examiners. Please refer to the students handbook for
further details.
