Ground-Based Simulation of Complex Maneuvers of a Delta-Wing Aircraft

Abstract

Ground-based simulations of complex maneuvers of a model of the X-31 aircraft have been performed in the lowspeed wind tunnel of the German–Dutch Wind Tunnels. In the wind-tunnel tests a novel test rig with 6 degrees of freedom was used for the first time for moving the model. Furthermore, the model was equipped with eight remotely controlled control surfaces. In this manner, maneuvers in which both the model and its control surfaces were moved simultaneously have been performed. Both the specific technical equipment of the model and the novel 6 degree of freedom test rig will be reviewed. Thereafter, experimental results obtained will be discussed.
