- Course objectives
-
Course Objectives: It is the instructor's intention to...
-
teach students the fundamentals of potential flow.
-
teach students the fundamentals of wing theory in both 2D and 3D.
-
teach students some of the fundamentals of propeller theory.
-
convey to the students the notion that mathematics is the only language suitable to describe the physics of aerodynamics.
-
show students the direct application and physical significance of the formalism of calculus learned during the first years of their undergraduate education.
-
convey to the students a knowledge of the limits of analytical solutions and the necessity, usefulness and accuracy of computational methods.
-
provide an opportunity for the students to improve their team-work and report-writing skills.
-
Course Outcomes: Students must be able to...
-
use superposition of the solutions to Laplace's equation for some simple, fundamental flows to model more complicated ones.
-
explain the concept of circulation and its relationship to the lift on an airfoil.
-
use a vortex sheet and vortex filament to model a 2D airfoil and wings of finite span.
-
explain the concept of lift-induced drag.
-
write their own simple computer programs to model a symmetric wing.
-
learn to use data manipulation software packages to present their results in a professional and effective manner.
-
carry out a computational project and write a detailed report about procedure and results in teams of two students.

EMA 521 meets twice per week for 75-minute lectures
- Contribution of course to meeting the professional component
- This course contributes primarily to the students' knowledge of engineering topics, but does not provide design experience.
The following statement indicates which of the following considerations are included in this course: economic, environmental, ethical, political, societal, health and safety, manufacturability, sustainability.
-
-
EMA 521 focuses primarily on the theory of wings and the lift and drag associated with airflow over those structures. It is primarily a technical course and does not cover any of supplemental topics (economics, environmental, etc) listed by ABET.
- Relationship of course to undergraduate degree program objectives and outcomes
- This course primarily serves students in the department. The information below describes how the course contributes to the undergraduate program objectives.
-
-
EMA 521 is focused to satisfy the EMA educational objectives by providing an education in a subject (aerodynamics) which is fundamental for those interested in making a career in the aeronautical or astronautical industry via problem solving, design-oriented problems and communication; e.g., including a team computational project that requires submission of a written report. This allows for career-related discussions in the context of aerodynamics analyses.
- Assessment of student progress toward course objectives
-
Weekly homework
-
One computational team project
-
Two exams
-
One final exam
-
Instructor evaluation forms filled by the students after the first exam and at the end of the semester
