Definition of a Simplified, Low-Cost, Constant Cross-Section High-Lift Wing Configuration Based on the Common Research Model (CRM-HLS)

A simplified, constant cross-section high-lift wing configuration is outlined, building upon the High-Lift Common Research Model (CRM-HL) ecosystem definitions. Our objective is to create a more flexible and cost-effective experimental platform without sacrificing the fidelity of the underlying physical mechanisms of interest. To achieve this, we derive a constant-section, constant-sweep wing whose geometry is directly extracted from the outboard region of the CRM-HL. The scale of primary features is increased such that the Reynolds numbers achievable on this configuration in conventional low-speed wind tunnel facilities are similar to the CRM-HL at the chosen slat bracket location in pressurized tunnels. This paper outlines the features of this geometry and the thought processes that led to the final definitions and configurations of interest. Plans for use of this geometry as part of the high-lift prediction workshop (HLPW) series and for testing at the University of Washington Aeronautical Laboratory (UWAL) are outlined, alongside the results of initial simulations.
