30P-30N Main Element (MDA)
Wing Geometry Simulator
The 30P-30N Main Element (MDA) is a thin 3.2% chord-thickness airfoil with a symmetrical cross-section (camber -2.7%), commonly used in aerobatic aircraft, rotorcraft blades, and tail surfaces where inverted flight symmetry is required.
Thin airfoil theory predicts a stall angle near 13.8° and a peak lift-to-drag ratio around 27 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The slim profile minimises pressure drag at higher speeds but leaves limited spar depth for structural integration.
Designers evaluating the 30P-30N-MAIN typically compare it against profiles of similar thickness: GOE 445 AIRFOIL, HT 13, NACA-M1 AIRFOIL, GOE 10K AIRFOIL, BOEING-VERTOL VR-9 AIRFOIL. The EPPLER EA 6(-1)-012 AIRFOIL is another reference profile frequently considered alongside it.
