The critical pressure coefficient with respect to the critical Mach number () is a parameter used in aerodynamics to describe the pressure coefficient () at which the flow over an airfoil or aerodynamic surface reaches a critical condition associated with the critical Mach number (). It provides insights into the behavior of the flow as it approaches and passes the critical Mach number.
- Specific heat ratio (γ)
- Critical Mach number (Mcr)
- Critical pressure coefficient (Cp,cr)
