This research predominantly centers on the streamlined qualities of Kline-Fogleman modified (KFm) airfoil. KFm arrangement airfoil family shows improved strength and low stalling which has made it quite popular for low weight conveying flight. Some of the major streamlined attributes like lift coefficient, drag coefficient, etc. of KFm-1, KFm-2, and KFm-3 have been explored and a correlation is made with the NACA 4415 airfoil. Spalart-Allmaras disturbance model is applied to the ANSYS Fluent commercial software. The setup is analyzed at a different angle of attack (AOA) methodologies stretching out from 0? to 15? and for a variety of Mach numbers ranging from 0.3 to 0.6. The Reynolds number was 3.18 ×105 . The purpose of this division was to reduce computational costs while utilizing CFD software. Computational assessments were coordinated to explore the streamlined presentation of the airfoil. The results highlighted that a steady and gradual increase in lift is possible by introducing the backward step. The overall aim of this assessment was to numerically inspect whether the streamlined execution of an airfoil can be improved by introducing a backward facing step on the upper surface of the airfoil.
