Normal force by Lilienthal Calculator

In aerodynamics, the normal force (often denoted as N) is a fundamental force that acts perpendicular to the surface of an object in a fluid flow, such as air. It is one of the four aerodynamic forces, along with lift, weight (gravitational force), and drag, that play a crucial role in the behavior and motion of an aircraft or any other object moving through a fluid. 

 

  • N is the normal force 
  • 0.13 is the Smeaton’s coefficient 
  • η is the normal force coefficient 
  • F is the Planform Area 
  • V is the freestream velocity
