Abstract : Wind-tunnel tests of a 1/144-scale model of the CVA 65 aircraft carrier were conducted to determine the local dynamic pressures in that portion of the air wake of the carrier normally traversed by an airplane approaching for a landing. The wake surveys were conducted with a pitot-static rake, for winds directly over the bow of the ship, and at yaw angles of 10 and 20 deg. Plots are presented showing the local dynamic pressure as a fraction of the free-stream dynamic pressure. One plot presents the dynamic pressure ratios encountered by an airplane flying a typical approach. The effect of the island of this carrier is somewhat larger and more pronounced than it is on a carrier with a conventional island. Sharp differences in the dynamic pressure patterns are seen between yaw angles of 10 and 20 deg. (Author)
