Abstract:The capabilities of the European Transonic Windtunnel ETW to simulate flight conditions by testing at cryogenic temperatures are presented. The achieved flow quality and tunnel control form the basis for an excellent data repeatability and a high confidence level in the deliverables. Unique instrumentation has been developed to provide additional information about the test object and the surrounding flow field during tunnel entries. Typical samples of Reynolds number effects are shown. Productivity aspects are considered on the basis of recently performed test scenarios.
