Airfoil Design vs Benchbuilt

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.

Benchbuilt turns vehicle engineering into a hands-on learning lab. Start with a production-inspired body, choose an engine, configure the drivetrain and chassis, then shape the body and test the result. Every choice feeds a physics-based estimate using real units and understandable explanations. Compare power, mass, frontal area, drag coefficient, traction, gearing, braking, and engine packaging without needing an engineering degree. BUILD YOUR VEHICLE • Choose from compact, fastback, roadster, sports sedan, and open-engine hot rod body packages • Install engines ranging from an efficient four-cylinder to high-output V8 packages • See whether the engine fits beneath the body or protrudes into the airflow • Configure transmission, tires, brakes, suspension, chassis weight, and fuel • Shape independent body control points to explore smooth profiles, wedges, and experimental designs TEST AND LEARN • Estimate top speed and 0–60 mph acceleration • Measure quarter-mile time and trap speed • Compare standing-mile speed, lateral grip, braking distance, and cruise range • Run road and wind-tunnel tests • Understand why drag, weight, power, traction, and gearing changed each result • Save builds for side-by-side engineering comparisons Designed for curious builders, students, classrooms, and anyone who has wondered why one car shape performs better than another. Benchbuilt works on iPhone and includes a spacious iPad workbench for classroom use. Benchbuilt provides educational physics estimates and is not intended for real-world vehicle certification or safety decisions.
