Airfoil Design is the ultimate tool for designing and analyzing aircraft wing sections. With advanced numeric methods, custom mesh generation, and real-time aerodynamic analysis, you can create and refine complex airfoil geometries with precision. Our CFD simulation engine accurately solves Euler's equations, providing insights into compressible, non-viscous flows, including shockwave formations. Key Features: - Design Flexibility: Generate and customize airfoil geometries with 4 types: NACA 4-digit, NACA 5-digit, Modified NACA 4-digit, and Modified NACA 5-digit airfoils. - Real-Time Analysis: Adjust airfoil shapes using intuitive sliders and instantly see the impact on aerodynamic coefficients. - Airfoil Import: Easily import existing airfoils from the airfoiltools.com database. - Custom Mesh Generation: Create o-type grid meshes with our built-in generator and export them for use in other applications. - Advanced CFD Simulation: Simulate airflow around your designs with our powerful CFD engine, now featuring touch pan/zoom, streamlines, CP vectors, and second-order solver. Visualize results with the new Coolwarm color map and export them as PDFs. Whether you’re a professional aerospace engineer or a student of aerodynamics, Airfoil Design offers the tools you need to innovate and explore. Download now to start your aerodynamic journey on your iPad or iPhone. Note: The app is continuously being improved, with new features and bug fixes on the way.
