Abstract : Wind-tunnel test of a 1/144-scale model CVA 64 carrier were conducted to determine the distribution of dynamic pressure in the area traversed by landing aircraft. The local dynamic pressures in the air wake were surveyed at three carrier angles of yaw: 0, 10, and 20 deg. Results are presented as ratios of local dynamic pressure to free-stream dynamic pressure at various locations in the wake. In addition, a plot is presented showing the dynamic pressures encountered by an airplane approaching on a 4 deg glide path at one set of conditions of wind-over-deck and airplane airspeed. From a dynamic pressure distribution standpoint, a ship yaw angle of zero is the most desirable. (Author)
