The testing used a semispan model with features simulating high-lift settings for takeoff and landing conditions. It was completed in December at a wind tunnel in Farnborough, England operated by QinetiQ. Researchers are still reviewing the full results, but according to officials the test has added valuable data to reduce fuel use in future aircraft designs.
Specific quantitative results from the testing have not yet been released. It remains unclear whether this design will lead to a full-scale flight demonstrator or when the full analysis will be published.
