This module will introduce the student to aircraft and rotorcraft performances. Performance estimation is needed to design new aircraft, to operate efficiently existing aircraft, to buy a new aircraft, to modify and upgrade existing aicraft, to extend the flight envelope, etc. The complexity of current aicraft is highlighted, and it is shown how more that 60 independent parameters may be required to characterize the vehicle – not including performance charts.

Measurements of performances are essential to this process, therefore some time will be devoted the the basic flight measurements (air speed, Mach number, altitude, etc).

International regulations (ICAO, FAA, CAA, MIL, etc) are part of the engineering and certification process (Certificate of Airworthness). The role of regulations will be highlighted throughout the course.

• Additional Literature for the enthusiasts

Notice

Handouts will be distributed during the lectures. None of the lecture notes will be made available on the internet. Lecture notes contain sample questions. No tutorial sheets will be available. Students are required to attend the tutorials and work out the problems assigned.

Assessment

• 2 hour closed-books exam at end of semester, 80 %
• Course work, laboratory work and set problems, 20 %

Notice

• Date and place of the exam is set by the undergraduate office sometime in the middle of the semester.
• Attending lectures is strongly recommended and will be strictly monitored.
• Class attendance will reflect upon your final grade.

Course Work Policy

• All laboratory and course work is to be submitted within 2 weeks from the date of the experiment or assignement
• Course work submitted after deadline will not be marked.
• Extension of the deadline can be granted, but only on a case-by-case basis
• Reports cannot be submitted via email or fax

How Much Should you Study ?

• 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 17:00-18:00, or via e-mail 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.
• The instructor expects silence from the students. Background noise will not be tolerated.
• Horseplay and willful misconduct have no place in the class room.
• No Smoking, No Drinking, No Eating.
• Learn More on the Students Chart.

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; copying from books; 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.
