Abstract
Near-field pressure signatures of several simple axisymmetrical models and a 69-degree delta wing body model are measured at JAXA’s 1- by 1-meter blow-down type supersonic wind tunnel in order to obtain validation data for sonic boom prediction tools. A static pressure rail which has 111 static pressure taps at 4mm interval is installed on the windtunnel wall. The height of the rail from the wind-tunnel wall can be changed in order to investigate the effects of the rail geometry and the shock/boundary layer interaction effects on the measured signatures.
