The research on the aerodynamic behavior of airfoils is based on the creation of aircraft modifications employing novel wing designs. The airplane will experience a lift force as a result of the action of aerodynamic forces. The current study compares the efficiency of airfoil NACA 0018 with NACA 64-208 as a baseline to determine the efficacy of airfoil shape based on different angles of attack. to denote the supersonic and subsonic instances, respectively. Simulating the specified airfoils based on angle of attack variations correlated with two Reynolds Numbers for each example was used to create the scenarios. The first consideration is low speed (Re 6,000,000), which serves as a baseline for all scenarios, and the second is supersonic speed (Re 60,000,000), which is defined by NACA 64-208. The air speed and pressure increase as the angle of attack increases until the angle of attack hits the stall angle, according to the CFD simulation results. It can be shown that wing shape design is an important component in determining aircraft speed based on lift force magnitude associated with aircraft mass, which constitute independent acceleration parameters
