An investigation has been made to obtain the effects of a 20-percent-semispan all-movable wing-tip control (which was deflected -5 to -10 degrees) on the longitudinal stability characteristics of a twisted and cambered 60 degrees sweptback-wing-indented-body configuration equipped with fences at angles of attack which generally varied from 0 to 16 degrees and over the Mach number range of 0.80 to 1.13. The Reynolds number based on the mean aerodynamic chord varied from 2,010,000 to 2,220,000.

An investigation was made in the Langley 8-foot transonic tunnel of the pressure distribution on a wing-body combination having a 45 degree swept-back wing with aspect ratio 4, taper ratio 0.6, and NACA 65A006 airfoil sections parallel to the plane of symmetry. The body had an afterbody which was cylindrical from the region of the leading edge of the wing-body juncture rearward to the base. Data were obtained at Mach number from 0.60 to 1.13. The test Reynolds numbers ranged from 1,740,000 to 2,030,000. In order to determine the effects on loads of a change in body shape, the results of this investigation are compared with similar data previously obtained for the same wing in combination with a body that was curved from the nose to the base.
