STATIC LONGITUDINAL AND LATERAL STABILITY CHARACTERISTICS AT LOW SPEED OF UNSWEPT-MIDWING MODELS HAVING WINGS WITH AN ASPECT RATIO OF 2,4, OR 6
Year: 1956
Abstract: A systematic investigation was made in the Langley stability tunnel to determine the effects of the various components and combinations of components on the static longitudinal and lateral stability characteristics at low speed of unswept-midwing models having wings with an aspect ration of 2, 4, or 6 through an angle-of-attack range from -40º to 32º. Also included are the effects of large angles of sideslip at several angles of attack for some of the components and combinations of components.
The results of this investigation have indicated that, at low and moderate angles of attack, decreasing wing aspect ratio decreases the tail contribution to longitudinal stability. Near the angle of maximum lift for the wing-alone configuration, there is a pronounced increase in longitudinal stability for all configurations involving the wing for all wing aspect ratios.
The results of this investigation have indicated that, at low and moderate angles of attack, decreasing wing aspect ratio decreases the tail contribution to longitudinal stability. Near the angle of maximum lift for the wing-alone configuration, there is a pronounced increase in longitudinal stability for all configurations involving the wing for all wing aspect ratios.
