## What do you learn in Aerodynamics

Aerodynamics covers the study of how air interacts with solid objects in motion. You'll dive into fluid dynamics, lift and drag forces, boundary layers, and airfoil design. The course explores subsonic and supersonic flow, shock waves, and computational fluid dynamics. You'll learn to analyze aircraft performance, stability, and control using mathematical models and wind tunnel experiments.

## Is Aerodynamics hard?

Aerodynamics can be challenging, especially if you're not a math whiz. It involves a lot of complex equations and concepts from fluid mechanics. The math can get pretty intense, with partial differential equations and vector calculus. But don't let that scare you off. If you've got a solid foundation in physics and calculus, you'll be able to handle it. Plus, the real-world applications make it worth the effort.
