First Comparison of CFD Simulation and Wind Tunnel Test of the Forward-Swept Natural Laminar Flow Model NLF-ECOWING-FSW
摘要
The forward-swept NLF-ECOWING-FSW model is designed to facilitate extensive natural laminar flow (NLF) at a high Mach number of 0.78. A wing-fuselage half-model with a half-span of 1.25 m was tested in the European Transonic Windtunnel (ETW). A first comparison of the experimental data with CFD simulations is presented in this paper. The objective is to understand the steady aerodynamics of the NLF-ECOWING-FSW configuration. This work aims at building the foundation for future unsteady investigations of this model.
