Airfoils
A sheet of metal cannot fly. A carefully shaped sheet of metal can carry hundreds of passengers across continents. What makes the difference? The answer is the airfoil. The airfoil is one of the most…
- 028 min
Angle of Attack
Understanding the single most important variable controlling lift, drag, and aerodynamic stall.
- 036 min
Aspect Ratio
Understanding how wing proportions influence lift, drag, efficiency, maneuverability, and aircraft performance.
- 047 min
Compressibility Effects
Understanding how air changes at high speeds and why compressibility transformed the science of aerodynamics.
- 057 min
Drag
Understanding the aerodynamic force that opposes motion through the air and why reducing drag is one of the greatest challenges in aerospace engineering.
- 067 min
High-Lift Devices
Understanding how engineers temporarily increase wing performance during takeoff and landing.
- 078 min
Lift
One of humanity’s oldest dreams was to fly. For thousands of years, people watched birds soar effortlessly across the sky and wondered: Why don’t they fall? How can a machine weighing hundreds of…
- 087 min
Shock Waves
Understanding the sudden pressure waves that define supersonic flight and transform the design of modern aircraft and spacecraft.
- 098 min
Stalls
One of the greatest misconceptions in aviation is: “An aircraft stalls because it flies too slowly.” This statement is incomplete. Aircraft can…
- 107 min
Supersonic & Hypersonic Aerodynamics
For thousands of years, humans dreamed simply of flying. Today, aerospace engineers design vehicles that…
- 116 min
The Four Forces of Flight
Understanding the four fundamental forces that govern every aircraft, from paper airplanes and gliders to jet fighters, helicopters, and spacecraft during atmospheric flight.
- 126 min
Thrust
A wing can generate lift. But lift alone cannot keep an aircraft flying indefinitely. Without forward motion: Airflow over the wings decreases. Lift disappears. Eventually: The aircraft descends. So…
- 137 min
Weight
Why can’t an aircraft simply keep climbing forever? Why do airplanes have maximum takeoff weights? Why do airlines carefully calculate passenger, cargo, and fuel distribution before every flight? Why…
- 147 min
Wingtip Vortices
Understanding the invisible spirals of air created by every lifting wing, why they generate induced drag, and how engineers reduce their effects.
- 157 min
Bernoulli’s Principle
Why does an aircraft wing produce lift? Why does air move faster through a narrow Venturi tube? How does a perfume atomizer spray liquid into the air? How does a carburetor mix fuel with air? Why…
- 168 min
Boundary Layers
Understanding the thin region of fluid next to a surface that governs drag, lift, heat transfer, and the performance of nearly every aircraft, ship, and engineering machine.
- 177 min
Continuity Equation
Understanding the Law of Conservation of Mass and why fluids speed up, slow down, and change direction in engineering systems.
- 187 min
Flow Separation
Why does an aircraft suddenly lose lift and stall? Why do some cars experience enormous aerodynamic drag while others slice smoothly through the air? Why do golf balls have dimples? Why do jet…
- 197 min
Fluid Flow
Understanding how liquids and gases move, and the fundamental concepts engineers use to analyze every flowing fluid.
- 207 min
Introduction to Computational Fluid Dynamics (CFD)
Understanding how engineers use mathematics, physics, and supercomputers to simulate the motion of fluids before building real-world aircraft, ships, rockets, and engines.
- 217 min
Laminar and Turbulent Flow
Watch smoke rising from a candle. Sometimes it rises as a smooth, elegant column. A few centimetres higher, it suddenly begins twisting and swirling chaotically. Why? Why does water flowing gently…
- 227 min
Reynolds Number
Understanding the dimensionless quantity that predicts whether fluid flow will remain smooth or become turbulent.
- 237 min
Streamlines and Flow Visualization
Learning how engineers make invisible airflow and water flow visible to understand lift, drag, turbulence, and propulsion.

What Is Fluid Dynamics?
Why does an aircraft wing generate lift? How does a jet engine produce thrust? Why does water flow through rivers? How do hurricanes form? Why do ships leave wakes behind them? How does a rocket…
