![]() In future, this airfoil database will be used to study novel concepts for aircraft engines. The benefit of using airfoils optimized for their specific purpose over having generic airfoil shapes is discussed as well. The database offers a wide variety of airfoils for different applications.Īirfoils for sub- and supersonic inflow are covered as well as airfoils suited for placement at hub or casing. VisualFoil Plus generates accurate aerodynamics data for experimental or existing airfoils where the information. It solves the 2D compressible Euler equations and computes the lift, drag and moment coefficients for airfoils in subsonic, transonic and supersonic flows. The optimized geometries of four of the airfoils under investigation are found in the appendix. VisualFoil Plus is a powerful CFD simulation software for airfoil analysis. ![]() To verify the optimization strategy, it is tested on a set of existing compressor airfoils. PDF On Jan 1, 2019, Wentao Yong published Study on Aerodynamic Characteristics of Supersonic Airfoil Find, read and cite all. The solver is well established among industry and research and it is validated to a high degree by experiments. Design and off-design performance is evaluated with the blade-to-blade flow solver MISES. The target is to find airfoil shapes that have low losses and ensure stable operation over wide incidence ranges. UIUC Airfoil Coordinate Database coordinates for nearly 1,600 airfoils John Dreeses NACA airfoil coordinate generation program Works on Windows XP, 7 and 8. To fill this seven-dimensional space, a large number of airfoils is generated by means of numerical optimization at discrete points in this space. The NACA airfoil series is a set of standardized airfoil shapes developed by this agency, which became widely used in the design of aircraft wings. These constraints include limitations for profile area depending on inlet Mach number and limits for axial Mach number. ![]() Additional constraints are imposed to ensure that feasible airfoils exist for each set of requirements. The database is structured in seven dimensions, denominated as 'design requirements': blade stagger angle, pitch-chord ratio, profile area and the following design point properties: inlet Mach number, Reynolds number, streamtube contraction and aerodynamic loading. This airfoil family is generated by filling a database with optimized airfoil shapes. This paper aims to generate a highly versatile compressor airfoil family that covers most applications in the core compression system of aircraft engines and stationary gas turbines. Ensuring a high degree of commonality among a range of products can dramatically decrease development costs.
