![]() CFD software Ansys Fluent is used to analyze the aircraft wing at two different AOA and at two different transonic speeds. New data are presented that permit the rapid calculation of the approximate pressure distributions for the older NACA four-digit and five-digit airfoils by the same methods used for the NACA 6-series airfoils. The Mach number of flow over the wing and the pressure plot at the wing symmetric plane at different aircraft speed and at different turbulence intensity levels are discussed in this paper. The historical development of NACA airfoils is briefly reviewed. This subsonic wing is analyzed using K-ω SST Turbulence model and for two different AOA of 0 0 and 4 0. Supersonic channel airfoil design techniques have been shown to significantly reduce drag in high-speed flows over diamond shaped airfoils by Ruffin and colleagues. A overview of Transonic aerodynamics and the Turbulence model used is presented in this paper. Based on these methods, two subsonic stages of a 4.5-stage transonic research compressor are redesigned. The airfoil sections of such wings produce the desired lift and, more importantly, yield less drag compared with the conventional blunt airfoils commonly used with subsonic flying vehicles. Together with the airfoil geometry, the database stores automatically calibrated correlations which describe the cascade performance in throughflow calculation. ![]() During the late 1920s and into the 1930s, the NACA developed a series of thoroughly tested airfoils and devised a numerical designation for each airfoil a four digit number that represented the airfoil section’s critical geometric properties. The results obtained by this work on subsonic wing can be used to compare the performance of this subsonic wing with respect to performance of Transonic and supersonic wings. The lifting surfaces of supersonic flying vehicles generally have sharp leading edges. National Advisory Committee for Aeronautics airfoils. This paper provides an effective method for supersonic aircraft to reduce the sonic boom and drag coefficient. In this paper the lift and drag coefficient of a finite 3D wing of a subsonic Aircraft is presented at transonic speed conditions and at different turbulence intensity levels. The environment conditions at which civil and combat aircraft operates are unpredictable and will change from one location to other based on weather and climate conditions. Aircraft's both for combat and civil purpose work under different environment conditions, especially when it is a combat Aircraft or a jet trainer it will be more often subjected to high level of turbulence due to max manoeuvring and shorter runway takeoff operations.
