1 Aerodynamics ASCI 309 Face to face Course Syllabus Credit Hours: 3 Credits Academic Term: Term IV: Meetings: Fri Sat/Sun , 29, 30 Mar 2, 3, 4 Location: Instructor: Office Hours: Spangdahlem Air Base, Germany; Face to face Dr. Herb Hoffmann Before and after class or by appointment (Central European Time) hoffm7d5@erau.edu Course Description: Students are provided with an opportunity to explore incompressible flow airfoil theory and wing theory. Topics center on: calculation of stall speed, drag and basic performance criteria, configuration changes, high and low speed conditions, special flight conditions, and an introduction to compressible flow. Prerequisites: MATH 112 and PHYS 102. Course Goals: This course is designed to provide students with the technical background necessary to understand the operating limitations and procedures of modern airplanes and to optimize pilot technique by properly defining required tasks. Learning Outcomes: 1. Using SI and British Gravitational System of measurement, solve aeronautical flight mechanic problems involving laws of motion, forces and energy. 2. Identify standard atmospheric variables and their sea level values. Compute atmospheric conditions using the universal gas laws. 1

2 3. Identify and define the relationships between indicated, calibrated, equivalent and true airspeeds and how they change with altitude and temperature. 4. Describe the effects of velocity, density, area and lift coefficient on lift. Solve stall speed problems and learn airfoil nomenclature and designations. 5. Explain wing stall patterns and factors affecting the stall. As well as explain the aerodynamic characteristics of spins and spin recovery. 6. Explain and describe the effects of flaps, slats, vortex generators and boundary layer devices on lift, drag and pitching moment coefficients. 7. Demonstrate and understand the factors affecting maximum performance events such as best range, max endurance, best glide, max angle climb and max rate of climb. 8. Explain stability, controllability and the factors in high speed flight such as speed ranges, critical Mach number, the Force Divergent Mach number, Mach tuck, control buzz and shockwaves. 9. Demonstrate and discuss the origin and effects of induced drag and methods utilized to reduce induced drag. 10. Explain factors affecting the maneuvering envelope and solve problems involving the turn equations. 11. Discuss how wing planform characteristics (i.e. wing area, wing span, mean aerodynamic chord, taper ratio, aspect ratio) affect lift, drag and aircraft performance. 12. Determine maximum range, endurance speeds and rate of climb airspeeds from plots of power, thrust and drag versus airspeed and understand wind and fuel flow effects. 13. Describe the cause and effects of compressibility and the aerodynamic design features for high-speed transonic and supersonic flight. 14. Describe aircraft stability and control, including the aircraft features that improve or degrade stability and control and the flight conditions where stability and control are critical. 15. Determine the origins and effects of parasite drag and methods utilized to reduce it. 16. The student will demonstrate appropriate selection and application of a research method and statistical analysis (where required), specific to the course subject matter.

4 Assignments, Discussion Board Participation (If required for Blended Delivery), and/or special administrative: All assignments will be completed in a professional manner and on time, unless prior arrangements have been made with the professor. Blackboard assignments (if required) are graded with class participation. This course includes weekly activities, each of which may have grade points associated with them. Unless prior arrangements have been made with the instructor, students are expected to participate each week, according to the course schedule. This is especially important with regards to discussion activities. Weekly discussions typically include both an initial posting and one or more substantive replies. Note: Proper etiquette has to do with keeping it simple by using proper English and proper spelling spell check works well in Blackboard. Course Policies: Embry-Riddle is committed to maintaining and upholding intellectual integrity. All students, faculty, and staff have obligations to prevent violations of academic integrity and take corrective action when they occur. The adjudication process will include the sanction imposed on students who commit the following academic violations, which may include a failing grade on the assignment, a failing grade for the course, suspension, or dismissal from the University: 1. Plagiarism: Presenting as one s own the ideas, words, or products of another. Plagiarism includes use of any source to complete academic assignments without proper acknowledgement of the source. All papers submitted for grading in this course will be submitted to safeassign.com - where the text of the paper is compared against information contained in the safeassign.com database. Papers submitted will be included in the safeassign.com database and become source documents for the purpose of detecting plagiarism. 2. Cheating: A broad term that includes the following: a. Giving or receiving help from unauthorized persons or materials during examinations. b. The unauthorized communication of examination questions prior to, during, or following administration of the examination. c. Collaboration on examinations or assignments expected to be individual work. d. Fraud and deceit, that include knowingly furnishing false or misleading information or failing to furnish appropriate information when requested, such as when applying for admission to the University. 3. APA 6 th edition format is the ERAU Worldwide standard for all research projects. Disability and Special Needs: ERAU is committed to the success of all students. It is a University policy to provide reasonable accommodations to students with disabilities who qualify for services. If you would like to request accommodations due to a physical, mental, or learning disability, please contact the Worldwide Campus Disability Support Service Office at (888) or via wwdss@erau.edu or worldwide.disability.support.services@erau.edu. 4
