Induced Drag Explained: Why Flying Slower Can Increase Drag
Induced Drag Explained: Why Flying Slower Can Increase Drag Why can an aircraft experience more drag when it flies more slowly? We usually associate greater speed with greater air resistance, but a wing must also generate enough lift to support the aircraft. Induced drag is the drag associated with producing lift on a finite-span wing. […]
Laminar vs Turbulent Boundary Layers: Why Airflow Separates from Aircraft Wings
Laminar vs Turbulent Boundary Layers: Why Airflow Separates from Aircraft Wings Airflow around an aircraft wing is often shown as smooth streamlines passing neatly over the aerofoil. In reality, the thin layer of air immediately next to the wing surface behaves very differently from the undisturbed airflow further away. This region is called the boundary […]
Why There Is No Perfect Aerofoil: The Design Trade-Offs Behind Every Aircraft Wing
Why There Is No Perfect Aerofoil: The Design Trade-Offs Behind Every Aircraft Wing If a designer could create a perfect aerofoil, it would produce very high lift with almost no drag, remain stable at every angle of attack, fit a lightweight structure inside the wing and work equally well at low and high speed. No […]
