The analyzed results demonstrate the aerodynamic performances in terms of drag and lift coefficients, pressure coefficients, static temperature for the various angle of attacks and mach numbers. Computational examinations were directed to upgrade the aerodynamic performance of the airfoil. For a variation of mach number extending from 0.3 to 0.6, the point of separation was resolved to employ CFD analysis. The numerical simulation was carried out with varying angle of attacks ranging from 0˚ to 15˚. Spalart-Allmaras turbulence model is employed on the ANSYS Fluent environment due to the transonic flow condition. Aerodynamic characteristics have been investigated for KFm-1, KFm-2, and KFm-3 followed by a comparison with NACA 4412 airfoil. ![]() KFm series airfoil family has better stability and low stalling effects which have made its use for low weight carrying flight. This article presents the aerodynamic characteristics of Kline-Fogleman modified (KFm) airfoil.
