Tangential (Axial) force by Lilienthal Calculator

In aerodynamics, the tangential force (also known as axial force or drag force) is one of the fundamental aerodynamic forces acting on an object moving through a fluid, such as air. It is perpendicular to the lift force and acts parallel to the direction of the freestream flow. 

 

  • T is the tangential or axial force 
  • 0.13 is the Smeaton’s coefficient 
  • θ is the tangential force coefficient 
  • F is the Planform Area 
  • V is the freestream velocity
