Prandtl-Glauert transformation Calculator

The Prandtl-Glauert transformation, also known as the compressibility correction, is used to correct the lift and drag coefficients calculated for an incompressible flow to account for the effects of compressibility at high speeds. It’s expressed as:

Where:

  • is the lift coefficient corrected for compressibility effects.
  • is the lift coefficient at a specific angle of attack in incompressible flow.
  • is the Mach number.
