The selection and design of aerofoils is the most important step in the aircraft design process. An aerofoil is the cross- sectional geometry of a wing that generates aerodynamic forces. When several aerofoils are piled together, they form a wing. The wing generates lift force, which counteracts the downward weight force. A complete examination of the shock, boundary layer, and other flow parameters must be undertaken before selecting any aerofoil for supersonic aircraft. Aerodynamic analysis is used to determine the vehicle's lift and drag coefficients, as well as estimate high- and low-pressure zones and separation points that affect vehicle performance. This analysis was done with CFD- Fluent, which is a fluid mechanics programme. For analysing and processing problems involving fluid flow, data structure and numerical analysis are used. The results of the aerodynamic analysis provide information on the many parameters and properties of the NACA 64-008A aerofoil. The analysis of a NACA 64 series supersonic aerofoil is the subject of this paper. The coefficients of lift and drag for three distinct leading edge radius at Mach 1.5 with a variable angle of attack are investigated. Pressure, velocity, and velocity stream line have been examined over the top and bottom surfaces of the NACA 64-008A aerofoil using Computational Fluid Dynamics.
KEYWORDS
This paper has mainly focused on finding the lift and drag coefficients obtained for a NACA 64008 aerofoil at a supersonic speed of Mach 1.5 when the flow angle was at degree 5, 0 and -5 for the three different leading edge radius are 5, 5.2 and 4.8. Propagation of shock waves was studied. It is analysed that the flow velocity greatly influences the characteristics of the boundary layer formed. Parameters like lift and drag forces, coefficient of lift and drag after analysing are summarized in the table 3.as the free stream velocity increases along the surfaces of the aerofoil, critical M is reached at some point after which shock was formed along the trailing edge. It clearly shows that for the increase in leading edge radius as considerable effect in the increase of coefficient that is for 5.2 leading edge radius for AOA positive 5 degree it clearly shows that there is an increase in lift and decrease in drag. Thus from this it is clearly observed that increase in leading edge radius as considerable effect in the increase in coefficient of lift
