摘要

介绍了欧洲跨声速风洞ETW通过在低温下测试模拟飞行条件的能力。所实现的流量质量和隧道控制构成了良好的数据可重复性和可交付成果的高置信水平的基础。开发了独特的仪器,以在隧道进入期间提供有关测试对象和周围流场的额外信息。显示了雷诺数效应的典型样本。生产力方面是在最近执行的测试场景的基础上考虑的。

ETW: simulations of true flight behaviour

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.
