Aerodynamic measurements

Limitations of magnetic balances The disadvantages of magnetic balances have so far limited the spread of their use to industrial…

Aerodynamic Drag Components

Drag is the force experienced by an object representing the resistance to its movement through a fluid. Sometimes called wind resistance or fluid…

Angle of Attack

The angle of attack of a turbine blade is the angle between the direction of the apparent or relative wind…

Wind Turbine Blades

Wind Turbines extract energy from the force of the wind on an aerofoil, in this case a turbine blade. The relative…

Aircraft Wings

Aircraft are kept in the air by the forward thrust of the wings or aerofoils, through the air. The thrust driving…

Newton’s Theory of Flight

Isaac Newton did not propose a theory of flight but he did provide Newton’s Laws of Motion the physical laws which can…

Dynamic Pressure

An important property of any gas is its pressure. Because understanding what pressure is and how it works is so fundamental to the…

Kutta Joukowski Theorem

Background and Historical Note: When asked how lift is generated by the wings, we usually hear arguments about velocity being…

Flow Around a Circular Cylinder

Flow around a circular cylinder can be approached from the previous example by bringing the source and the sink closer.…

Velocity Effects on Aerodynamic forces

Aerodynamic forces are generated whenever an object moves through a liquid or gas. From Newton’s second law of motion, the aerodynamic forces on…

Density effects on Aerodynamic forces

Aerodynamic forces are generated whenever an object moves through a liquid or gas. From Newton’s second law of motion, the aerodynamic forces on…
