Mastering Airfoil Selection for Drones - Part 1

In this video, we explore the theory behind how airfoils work — the foundation of flight. You’ll learn about the geometry of an airfoil, how lift and drag are generated, and how factors like angle of attack, camber, and thickness affect performance.

We explain Bernoulli’s principle, lift and drag coefficients, stall behavior, turbulence, and the effects of Reynolds number on aerodynamic efficiency. You’ll also see how pitching moments and trim drag arise from cambered airfoils.

All concepts are illustrated through interactive simulations using SIMNET, the cloud-based drone design and flight training platform.

In the next video, we’ll move from theory to practice and show how to select the most suitable airfoil designs.
