Recorded airfoil sections
Bendix Helicopters J
The UIUC airfoil-usage tables record the Bendix Helicopters J with 2 airfoil sections. Each is in the library with its geometry, a stored polar sweep, and DXF and .dat export. The source lists names only — it does not say which station carries which section — so they appear here thickest first.

wing designs
The sections above are what the source records, not a wing anyone drew. Wings that were drawn — planform, sections and the analysis behind them, all readable — are published under Full-scale aircraft wing designs.
Aircraft-to-section mapping from the UIUC airfoil-usage tables. Section geometry is computed from the library's CST fit; nothing here is a performance claim about the aircraft. All recorded aircraft
