3. 강의목표

The overall objective is to introduce qualitative (physical) and quantitative
(mathematical) descriptions of incompressible inviscid fluid motions and the associated aerodynamic
forces on aerodynamic bodies such as aircraft wings, rotor blades, and wind turbine blades.
Students will be introduced to basic theoretical, experimental and computational techniques for
aerodynamic system design. Special sessions will be arranged to help students with course material,
computer programs, and design projects.

비고
There will be 5 homework sets (20%), a midterm exam (20%), a final exam (30%),
and a wind-turbine design project (30%). Homework sets will be collected in class on their due
dates. No late homework sets will be accepted. Students may work together to solve problems, but
must submit their “own work" for grading.

Grades: A: 90-100, B: 80-89, C: 70-79, D:60-69, R:< 60 (based on scaled scores)
Any grading disputes should be made to the instructor within one week after the graded work is
returned.
Honor Code: Cheating and plagiarism is unethical behavior and is not tolerated in this course
or at POSTECH. POSTECH p이icy on cheating and plagiarism will be strictly followed.

9. 수업운영

Wind-Turbine Design Project: At the beginning of the course, students are encouraged to
team up with four to five classmates and to start conducting a preliminary literature survey on
wind turbine aerodynamics. Once students learn the fundamental aerodynamics theories, they will
need to start the design of a miniature (∼30 cm span) wind turbine blade. Students will use a
prototyping toolset consisting of a CAD program and a plastic milling machine, to manufacture
plastic wind turbine blades. The performance of students' wind turbine blades will be assessed by
the amount of electric energy converted from wind provided by a blower and a report discussing
the design process and performance analysis.
