This paper describes the development process of the low-speed configuration of the CRJ-700, with an emphasis on half-model high Reynolds number wind tunnel testing. The process included CFD design and analysis, wind tunnel tests and flight tests. The experimental development of the flaps and slats was performed using a 7% scale half-model, in the IAR 5ft x5ft High Reynolds Number wind tunnel. Results from these tests are in very good agreement with flight test data and decisions made in the wind tunnel lead to a short and successful flight test program.
