Note (General): In order to improve the weather cock stability derivative Cnβ of the NAL STOL research aircraft model, some surveys of the flow field around the empennage for the STOL landing configuration were carried out. The down wash angle, the side wash angle, and the dynamic pressure at the aerodynamic center of the empennage (25％ mean aerodynamic chord) were obtained by means of linear interpolation of the values measured at the two sections perpendicular to the free stream. Effects of the engine thrust coefficient and the two types of vortex generator on the flow field, and the directional stability in the case of an inner engine becoming inoperative, were studied with reference to the results of the force tests.
