Abstract

A wind tunnel model of an aircraft carrier was used to make air wake measurements. Particle image velocimetry measurements of turbulence intensity were made on a center plane intersecting the angled deck of the aircraft carrier. The factors of interest for the study were model pitch, yaw, island location, and island type. Two island types were used, a representative shape of current designs and an ideal streamlined airfoil shape. Each factor was studied at two levels in order to provide linear models using a Design of Experiments factorial design. From the data for each experimental combination, regression models for turbulence intensity were generated for five locations along the glide slope of an aircraft landing on the angled deck. Tests were also done to check the validity of the linear models. The models generated by the designed experiment were used to give recommendations on what factor settings result in the largest reduction of turbulence intensity along the glide slope. Also generated from the experiment were contour plots of velocity and turbulence intensity and line plots showing the turbulence and velocity trends along the glide slope.
