1. Spring 2010AE172: Introduction to Aircraft Performance Asst. Prof. Dr. Ali Türker Kutay Middle East Technical UniversityDepartment of Aerospace Engineering

2. Introduction • Instructor • Asst. Prof. Dr. A. TürkerKutay • BSc, METU, Aeronautical Engineering, 1996 • MSc, METU, Aeronautical Engineering, 1999 • PhD, Georgia Tech, Aerospace Engineering, 2005 • Students • METU Aerospace Engineering Students • In top 10,000 among over more than 1 million people • Course • AE172: Introduction Aircraft Performance • We learn how the aircrafts fly!

3. Teaching Philosophy • I will present the materials in a way that is easiest to understand for MYSELF • Everybody has a different way of learning • Student participation is very important • Majority of learning takes place outside the classroom • Always look for ways to better understand the materials • Share your knowledge with the class • You cannot lose knowledge by sharing it. You can only gain more!

4. Flight Dynamics • } • Control motion of the vehicle in 3D space • Position (3 translational states) • Orientation (3 rotational states) • 6 Degrees of Freedom (6DOF) y Yaw Pitch x Roll z

5. Four Forces of Flight

6. Generation of Lift
