Keywords: low speed flight, performance testing

The European Transonic Windtunnel (ETW) provides the capability for achieving flight Reynolds numbers (Rn) by testing at varying pressures and cryogenic temperatures. This capability was recently exploited to assess the low speed flight performance characteristics for the Boeing 787 commercial transport. High productivity combined with high data quality in both tunnel operations and model design / manufacture has provided early access to a substantial flight Rn performance database. The final determination on how well the ETW data characterized flight performance will follow flight testing in 2007-2008.
