Abstract:

Tests were conducted in the VKFA and PWT4T wind tunnels at AEDC to obtain captive trajectory, aerodynamic loads, and flowfield data in order to assess the ability to reproduce trajectories from tunnel to tunnel. The data were obtained with a 0.05-scale generalized shape aircraft model, an ogive- cylinder store model, and conical flow survey probes at and near the centerline fuselage station pylon and the wing 13-semispan station pylon. The tests were conducted at a Mach number of 1.63 with aircraft model angle of attack set at zero. Generally, the trajectories obtained in the two wind tunnels compared well. There was very good agreement in the translational motion of the store trajectories, with only slight differences in the angular motion in selected cases.
