In this module, you’ll learn the fundamental physics and engineering principles that govern how fixed-wing aircraft fly—and how to turn those principles into real design decisions.
We’ll begin by building an intuitive understanding of lift, drag, and wing aerodynamics, then break drag down into its individual components so you can see exactly where performance is gained or lost.
From there, you’ll learn how aircraft remain balanced in flight by understanding pitching moments, stability, trim, and center of gravity placement—critical concepts for designing drones that actually fly as expected.
Finally, we’ll move from theory to application by introducing thrust-to-weight ratio, wing loading, stall speed, and other key performance constraints.
