WingFlow vs Benchbuilt

WingFlow is a mini, interactive Computational Fluid Dynamics (CFD) app for iOS that lets you explore how wings and airfoils behave in flight. Selected as a winner of Apple’s 2026 Swift Student Challenge, WingFlow makes aerodynamic concepts visual, interactive, and easy to understand. Features: • Choose from popular airfoil designs including: Trainer (based on the Cessna 172) Glider Utility (inspired by STOL aircraft) • Design your own airfoils in the Custom Wing Builder: Adjust camber, chord, and thickness See changes update in real time • Fine-tune simulation settings with interactive sliders: Airspeed Angle of attack Particle density (simulation load) • Watch live lift and drag gauges respond instantly to your changes • Tap tooltips (?) throughout the app to learn aerospace concepts and terminology Experiment, learn, and see the physics of flight come to life.

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.
