NACA-WR-L-704

Abstract

INTRODUCITON <br>At the request of the Material Command, Army air Forces, 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 crifices. the models were identified by station numbers of 85, 250, 430, and 620, respectively, of the wing of the XB-33 airplane. This wing is formed by fairing between an NACA 65,2-222 a = 1 root section and an NACA 65,2-415 a = 0.5 tip section. <br>Sections number 85 and 430 were represented by simple airfoil models without flaps.
