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. Prerequisite: RSCH 202 Prerequisites

 MATH 112: College Mathematics for Aviation II

 PHYS 102: Explorations in Physics Strongly Recommended Knowledge Base by Topic

 Algebra

 Trigonometry

 Physics 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. Master Course Outline Learning Outcomes

Upon successful course completion, students will be able to:

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.

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.

Worldwide Learning Outcomes

Upon successful course completion, students will be able to:

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.

Grading Policy All evaluated activities and deliverables carry a maximum possible score of 100. The Grade Center in Canvas automatically calculates and weights the scores according to categories that make up the final course grade (see the table below). Consequently, your final grade is based on the weighted scores, not a total score. If you have questions about the grading policy, please contact your instructor privately.

Course Grade Scale Evaluation Items & Weights

90 – 100% A Discussion 20%

80 – 89% B Exercises 30%

70 – 79% C Midterm Exam 25%

60 – 69% D Final Exam 25%

0 – 59% F Total 100%

Discussions The Discussion Board is for interacting with your instructor and fellow learners to explore questions and comments related to aerodynamics. It is expected that each student engage in an open and constructive dialogue related to the questions and other discussions. Responses to the weekly discussion questions are required and must be completed within the module dates listed in their respective activities unless modified by your instructor. Your participation in each forum is evaluated on a 0 to 100-pt scale primarily for content indicating analytical thought with a slight emphasis on writing skills to assure interpretability of responses. Exercises Exercises relevant to weekly topics are to be completed at the end of each week and submitted for grading. To assist you in solving and understanding the exercises and their application, common errors and guidance are provided within the assignments. Each exercise assignment is worth 100. Exams The Midterm and Final Examinations consist of multiple choice, computational (formula application), and analysis of theory questions. Both examinations are delivered entirely online and are open books and open notes, but must be completed independently, without any help from anyone. Diagrams and tables from the Doyle and Lewis textbook are required and are supplied in a printable format for your convenience in Modules 5 and 9.

The Midterm Exam is administered in two parts. This exam covers the learning content in Modules 1 through 5.

 Part 1 - 10 Questions

 Part 2 - 20 Questions

The Comprehensive Final Exam is administered in two. This is a comprehensive exam covering the learning content in Modules 1 through 9.

 Part 1 - 20 Questions

 Part 2 - 20 Questions Lectures, Example Problems, and Aviation Videos and Articles Lectures, example problems, presentations, and aviation articles and videos are provided to supplement the information in the textbook.

End of Chapter Problems and Solutions

You are required to solve the problems at the end of the chapters in Flight Theory and Aerodynamics (Doyle & Lewis). The purpose is to for you to diagnose any misunderstanding and validate your understanding of the methods used in solving aeronautics problems by comparing your answers with those in the back of the chapters. Some Select Solutions are provided to demonstrate how to solve particular problems to facilitate the learning process. Online Sources

Several electronic systems are available and other methods may be used at the Instructor’s discretion. Online Learning This course is offered through Embry-Riddle Online (Canvas) and runs nine (9) weeks. The first week begins the first day of the term and ends at midnight EDT/EST (as applicable) seven days later. Success in this course requires in-depth study of each module as assigned, timely completion of assignments, and regular participation in forum discussions. Late work should be the exception and not the rule and may be downgraded at the discretion of the Instructor, if accepted at all. Unless all work is submitted, the student could receive a failing grade for the course. Extensions may be granted for extenuating circumstances at the discretion of the Instructor and only for the length of time the Instructor deems appropriate. The most important element of success in an online course is to communicate with your Instructor throughout the term. Conventions of “online etiquette,” which include courtesy to all users, will be observed. Students should use the Send Message function in Canvas for private messages to the Instructor and other students. The class Discussion Board is for public messages

It is highly recommended that students keep electronic copies of all materials submitted as assignments, discussion board posts and emails, until after the end of the term and a final grade is received. When posting responses in a discussion forum, please confirm that the responses have actually been posted after you submit them. [Course Schedule begins next page.]
