The report deals with some of the experimental test setups and recent results from the wind tunnel tests in the transonic wind tunnel of the DLR project called 'Aerodynamic Simulation of Unsteady Manoeuvres' (AeroSUM). AeroSUM is an interdisciplinary project involving the Institute of Aerodynamics and Flow Technology and the Institute of Flight Research as well as the Transonic Wind Tunnel in Gottingen. The main focus of the project is the numerical simulation of unsteady manoeuvres of fighter aircraft. It will be achieved by solving the time dependent Navier-Stokes equations simultaneously with the inertial equations of the motion of the aircraft. For the validation of these methods it is necessary to establish a dynamic data set investigating a wind tunnel model carrying out dynamic movements. States of critical flow, in which e.g. the topologies of flow change, must be investigated as well
