Analysis Tools

Kulfan CST Airfoil Generator
01

Interactively generate and manipulate airfoil surfaces using Kulfan's CST parameterization theory.

Airfoil Search Database
02

Explore a database of 1,600+ shapes, filtered by geometric properties and performance metrics.

Aerodynamic Airfoil Selector
03

Find the optimal airfoil for your specific flight conditions and wing geometry using aerodynamic weighting.

Compare Suite — Polar Overlay
04

Overlay Cl/Cd/Cm polars for up to 5 airfoils simultaneously. Export batch DXF or Selig .dat files.

Wing Generator — 3D Planform Designer
05

Design a 3D wing with a multi-station table — set span position, leading-edge sweep, chord, and airfoil section at each station.

Airfoil Profile Optimizer
06

Automatically tune CST parameters to maximize L/D or meet a Cl target at a given Reynolds number using gradient-free optimization.
