Tests were made in the Langley two-dimensional tunnel of four models submitted by the Glenn L. Martin Company as intermediate sections of the wing of the XB-33 airplane. The models were of 24-inch chord and were constructed of wood with pressure-distribution orifices. The models were identified by station numbers of 85, 250, 430, and 620, formed by fairing between an NACA 65,2-222 a = 1 root section and an NACA 65,2-415 a = 0.5 tip section.
