Aerodynamics is the study of gas molecules as they flow around objects. Its greatest benefit is its inducement of lateral motion in airfoils; either up (lift) in aircraft wings or down (force) in vehicle spoilers.
An airfoil achieves lateral movement by altering the air velocity over two opposite faces. The faster the air travels, the lower its pressure.
Up-lift is induced in an aircraft wing, due to the faster air travelling over its upper surface, lifting the aircraft off the ground.
Down-force is induced in a vehicle spoiler for the opposite reason; forcing the vehicle into the ground and therefore increasing frictional grip between its tyres and the road surface.
Whilst these calculations are relatively straightforward once they are understood, they can be a little confusing to the uninitiated.
Aerodynamics provides a user-friendly solution for those with a limited knowledge of the subject, but with a need.
The aerodynamics calculator determines the dimensional properties of both high-lift and low-drag airfoil sections including the expected 'angle of attack' that will result in zero-lift, and the expected lift-force when the angle of attack is zero.
Aerodynamics also calculates the performance characteristics of an airfoil at various non-zero angles of attack for both up-lift and down-force applications.
Whilst both airfoil performance calculation options are 'stand-alone', they allow for the automatic transfer of input data from the dimensional calculation options if preferred.
