Abstract

Within the scope of the „WEAG THALES Joint Programme 12.15 project“ an investigation of the vortex behaviour over a delta wing model under one angle of incidence and different angles of roll has been performed using Particle Image Velocimetry (PIV) under transonic conditions at DLR Göttingen, Germany. The investigation used a dual-stereo PIV arrangement with four cameras in forward-scatter mode. It was necessary to observe the optical system by means of additional cameras, as the starting and stopping of the tunnel affected the light sheet position. For one Mach number and angle of incidence steady measurements were conducted as well as 3 free rolling measurements ($ = 30°/40°/60°). A total amount of 100 Gb of raw data were acquired.
