bareHULL.3D

An airfoil which has been designed for low Reynolds (≤500.000) number applications. There are many systematic experimental data available by various wind tunnels at low-Re regime.

The "e387-windTunnel.dat" file has the coordinates of the section which used in the NASA Langley LTPT (Low-Turbulence Pressure Tunnel) experiments. [1]

The .3dm and .igs files have also the E387 (E) section curve information. This section used in the wind tunnel test has modified version of the original and has a blunt trailing edge.
