ABSTRACT:
A wind tunnel roll-moment and axial force balance which minimizes mechani and electrical interaction due to pitch and yaw loads on the roll moment and axial force measurement sections. The axial load section has four beams arranged in a cruciform connected via a plurality of deflection beams to a gage beam of thin-rectangular cross section located at the aft portion of the axial section. The roll section has a series of torsion webs circumferentially spaced at the lower and upper periphery of the section. A plurality of thin rectangular beams including the gage beam connect the forward and aft portions of the non-webbed area.
