An investigation was conducted to determine the multiaxis thrust-vectoring characteristics of the F-18 High Alpha Research Vehicle (HARV). A 0.10-scale model was modified with hardware to simulate the three-vane thrust vectoring system of the F-18/HARV. This investigation was conducted at Mach numbers ranging from 0.30 to 0.70, at angles of attack from 0 to 70 deg, and nozzle-pressure ratios from 2.0 to approximately 5.0. Results indicate that the thrust vectoring system of F-18/HARV can successfully generate multiaxis thrust vectoring. During vectoring, resultant thrust-vector angles were always less than the corresponding geometric vane deflection angle and were accompanied by large thrust losses.
