B29ROOT
B-29 ROOT AIRFOIL
Wing Geometry Simulator
The B-29 ROOT AIRFOIL is a 12.7% chord-thickness airfoil with a maximum camber of 6.4% at 30% chord, suited to high-lift UAV wings, RC sailplanes, and low-Reynolds-number slow-flyers. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -6.4°.
Thin airfoil theory predicts a stall angle near 11.3° and a peak lift-to-drag ratio around 70 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 13% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.
Designers evaluating the B29ROOT typically compare it against profiles of similar thickness: EPPLER 583 AIRFOIL, GOE 367 AIRFOIL, EPPLER 604 AIRFOIL, AH 94-145, GOE 433 AIRFOIL. The GOE 410 AIRFOIL is another reference profile frequently considered alongside it.
