An experimental and theoretical investigation of the effects of planform on the supersonic aerodynamics of low-fineness-ratio multibody configurations has been conducted in the Langley Unitary Plan Wind Tunnel at Mach numbers of 1.60, 1.80, 2.00, and 2.16. Longitudinal and lateral-directional aerodynamic force and moment data and flow visualization photographs were obtained for three multibody configurations. In general, the data indicated that planform has a small effect on the zero-lift drag of a multibody configuration. In contrast, the longitudinal aerodynamic data obtained at lifting conditions indicated that planform has a significant effect on the lift, pitching-moment, and drag-due-to-life characteristics of a multibody configuration. Although planform significantly affected the lateral-directional stability of the multibody configurations, the data did not uncover any unusual stability traits associated with the multibody configurations.
