摘要

The Boeing Company performed an extensive high speed test campaign at the European Transonic Windtunnel using a 4.5% scale 787 half span model to acquire force and pressure data at transonic conditions for a large range of Reynolds numbers including flight conditions. The test conditions were selected to provide a unique link between established wind tunnel databases and flight test data. The model incorporated a high speed wing equipped with extensive pressures instrumentation to enable the acquisition of high quality loads data up to and including the boundaries of the test envelope. The model included design features to enable configuration changes to be performed quickly resulting in high levels of productivity. This paper summarizes this test campaign and some of the results.
